Hardware Features

The IWT-128 Transmitter module allows almost any number of analog or digital input values to be wirelessly transmitted to a remote receiver with either analog 4-20 mA, 0-10 V, Ethernet, RS-485, or RS-232 outputs.
It can produce 2 types of analog output: voltage and mA source. It provides local control over analog and digital output Isoslice units.
A built-in display allows local monitoring of the individual inputs and outputs and displays menu options when the unit is configured.
The unit can be powered by a DC voltage between 16 and 36 V dc or 16 and
32 V ac.
The instrument is packaged in a compact 22.5 mm wide enclosure which can be mounted on a standard TS35 DIN-rail.
The system can be expanded through the use of optional Isoslice I/O modules. These modules connect automatically via the DIN rail-mounted bus connector, allowing the easy addition and removal of extra I/O.

Isolation Details

The IWT-128 has full 3 port isolation of 1000 V between the Output Stage and Power Supply for functional reasons.

UNPACKING

The instrument should be carefully inspected for signs of damage that may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.

QUICK START GUIDE

There are several different ways the IWT-128 can be used, here we show a QUICK START example.

Example 1

A standard IWT-128 gathers data from 3 Isoslice-2 units and sends this data every two seconds to the remote receiver,

The standard IWT-128 has no inputs or outputs, so it does not have or need its channel number.
Refer to the Isoslice-2 installation instructions to allocate channel numbers using the internal dip switches.
Fit the IWT-128 and the Isoslice-2 units onto the din rail.
Connect up the inputs to the Isoslice-2 units.
Connect up the power to the IWT-128 and switch it on (see section 4).
The IWT-128 will scan the bus, identify the Isoslice-2 units and commence reading them, and sending data to the remote receiver every two seconds.

CONNECTIONS

The IWT-128 is housed in a compact DIN rail mounting enclosure, with terminals, arranged in 4 rows. The Communications ports are on the top and the power supply and analog output are on the bottom rows.
The diagram below shows how to connect to an IWT-128 with an analog output .

If the radio stops receiving acknowledgments, it will reset after 10 attempts.

CALIBRATING THE IWT-128

When the unit is shipped the IWT-128 will be calibrated for the output type and range noted on the side label if it is fitted. If this label is blank then the unit will be calibrated for 4-20 mA output.

The display is used to show scaled values of the inputs and outputs in the system, or ON and OFF for digital inputs and outputs. The left button scrolls through the available channels, and the right button scrolls through the available parameters. Whilst the button is held down, the channel number is shown on the left of the screen, and the parameter is shown on the right. The led on the display will flash every 3 seconds to indicate to the user that the unit is operating. The display can be configured to remain on all the time or switch off after 15 minutes.

Data is sent to the remote receiver for each channel at the TRANSMIT time rate.

To exit from the main menu and return to run mode, press and hold both buttons for 2 seconds until OK is displayed on the screen.

After two minutes of inactivity from the front buttons when the main menu (or a sub-menu) had been accessed, a timeout will occur and the unit will automatically return to run mode.

Select IWT-128 Channel (1. CHANNEL)

If the IWT-128 has an output it must be allocated a channel number on the system, so that its data values can be identified correctly by the remote receiver.
The channel number chosen must not be a duplicate of any other device within the system.

Channel numbers can be selected between 1 and 128. By default, the channel number is 12. (The IWR-Port will automatically add channels as it receives data from remote units. If the IWT-

128 channel is changed when the remote receiver is operating, power cycle the remote receiver to remove data from the now unused channel).

Output Span and Output Zero (2. OUT SPAN and 3. OUT ZERO)

The output span and output zero values are learned if there is an output fitted to the IWT-128.

Press and release both buttons together to go to the main menu

2.OUT SPAN| Push the raise button once to change the menu item
3.OUT ZERO| Press and release both buttons together

4.DSV Cc Pp is used to select the channel and parameter that need display values changing, where c represents the channel and p indicates the parameter.
To select a different channel or parameter enter the submenu. The display will show the channel on the left and the parameter on the right. The lower button increases the channel (1 to 32) and the raise button increases the parameter (1 to 8).
For the channel and parameter chosen in menu 3:
5. DS span indicates what the display span value is (span is –999 to 9999) To change the display span value enter the sub-menu and adjust it.
6. DZ zero indicates what the display zero value is (zero is –999 to 9999) To change the display zero value enter the sub-menu and adjust it.

View Display Scaling Values (7.VIEW DSV)

To view all eight parameter scaling values of a particular channel, enter this sub-menu. The first channel shown will be the one selected in 4.DSV Cc Pp. The scaling values will be shown in a scrolling message in this format:
e.g. for channel 3:

C3.P1 100,0 P2 20,4 P3 100,0 P4 100,0 P5 100,0 P6 100,0 P7 100,0 P8 100,0

The channel being viewed can be changed using the lower or raise buttons, each press will cause the scrolling message to begin again, this time for a different channel.

Display Timer (8.DISPLAY display)

Choose if the display remains on all the time or switches off 15 minutes after a button was last pressed.

ON Select this to make the display stay on all the time
15 Select this to make the display switch off after 15 minute

Age Select (9.AGE age)

The age of a parameter can be counted in seconds or minutes, which will depend on the update of the wireless sensors concerned. Use this menu to select between

SEC select this to count in seconds
MIN select this to count in minutes

Transmit Time Period (10.TRANSMIT time)

The update rate for the IWT-128 to transmit data to the IWR-Port can be varied in 0.5-second increments from every 2 seconds to every 127.5 seconds.
The default is every 2 seconds.

ISOSLICE BUS

If the IWT-128 has an output fitted, it will need to have its own channel number in the range 1 to 128 (see section 6.2). This channel number must not exist elsewhere in the system.

Isoslice units connected to the IWT-128 must-have channel numbers that exist nowhere else within the system.

The Isoslice units are powered by the Din rail mounted bus connectors.

The IWT-128 will scan the bus when it powers up to find Isoslice units that are attached.

Each Isoslice is read twice a second.

If an Isoslice unit needs to be added to the bus, first switch the power off, add the new Isoslice unit and switch the power on again.

Channels are allocated to wireless devices and Isoslice units within the system, the channels must not be duplicated.

If scaling data is entered on an IWT-128 that has an Isoslice bus, it will be local to the display of the IWT-128. The same information would need to be entered on the IWR-Port as well.

INSTALLATION

The IWT-128’s output circuit is classed as Separated Extra Low Voltage (SELV). This means that they must not be externally connected to voltages exceeding 30 V ac or 60 V dc, nor do they generate voltages above these limits internally. Where a higher voltage input is required a specially designed DIVIDER unit can be used to condition the input signal before connection to the process input terminals.

The IWT-128 unit clips directly onto the ‘Top Hat’ (TS35) symmetrical DIN rail. Ideally, the mounting orientation should be vertical. Good airflow around the unit will maximize the reliability of the instrument.

The use of ferrules is recommended for wiring terminations.

Do not exceed terminal torque rating of 0.4 Nm – use an appropriate screwdriver. The unit can be removed from the DIN rail by sliding a small screwdriver into the slot at the rear of the enclosure on the lower face and gently levering the metal clip, whilst lifting the unit from the rail.

TROUBLESHOOTING

The IWT-128 has some built-in self-diagnostic functions. Errors encountered will be displayed on the screen.
