Notes:

• Use with copper conductor.
• Use in Pollution Degree 2 Environment .
• Power Supply must be Class 2.
• When supplied by an Isolated Limited Voltage/Limited Current power supply a fuse rated max 2.5 Ashall be installed in the field.

1. No linearization function connected
2. Linearization functions operate only in the 0..100% rated range, whereas for the under-range and the over-range, the input signal is transferred without any alteration (G=1). Continuity and monotonic quality of transfer guaranteed throughout the entire range of measurement
3. In the 0..1% section, the curve is linear with gain G=10 in order to avoid over-amplification of the noise in the initial section of the measurement range.

Installation rules

• This module has been designed for assembly on a DIN 46277 rail. Assembly in vertical position is recommended in order to increase the module’s ventilation, and no raceways or other objects that compromise aeration must be positioned in the vicinity.
• Do not position the module above equipment that generates heat; we recommend positioning the module in the lower part of the control panel or container compartment. We recommend rail-type assembly using the corresponding bus connector (Code K-BUS) that eliminates the need to connect the power supply to each module.

Inserting the module in the rail

1. Attach the module in the upper part of the rail.
2. Press the module downwards.

Removing the module from the rail

1. Apply leverage using a screwdriver (as shown in the figure).
2. Rotate the module upwards.

Using the K-BUS connector

1. Compose the K-BUS connectors as required in order to obtain the number of positions necessary (each K-BUS permits the insertion of no. 2 modules).
2. Insert the K-BUS connectors in the rail by positioning them on the upper side of the rail and then rotating them downwards.

IMPORTANT: Pay particular attention to the position of the protrudent terminals of the K- BUS. The K-bus must be inserted in the guide with the protrudent terminals on the left (as shown in the figure) otherwise the modules are turned upside downs.

• Never connect the power supply directly to the bus connector on the DIN rail.
• Never tap power supply from the bus connector either directly or by using the module’s terminals.

SETTING OF THE DIP-SWITCHES

Factory setting
All the module DIP switches are at pos. 0 as defaut configuration. This set correspond to the following configuration :

• Input signal: 0 – 20 mA
• 50-60 Hz mains frequency rejection: 50 Hz
• Input filter: Present
• Inversion: No
• Linearisation: None
• Output signal: 0 – 20 mA
• Input Out-of-range: ± 5% limit

It is understood that this configuration is valid only with all the DIP switches at position 0. If also one Dip is moved, it is necessary to set all the other parameter as indicated on the following tables.
Note: for all following tables

• The indication indicates that the DIP-switch is set in Position 1 (ON).
• No indication is provided when the DIP-switch is set in Position 0 (OFF).

Input Out-of-Range Limits
The Out-of-Range Limits provided in the following table are applied to the input signal, whereas the fixed limits are applied to the output signal: 0 – 21 mA, 0 – 5,25 Vdc, 0 -10,5 Vdc.

Electrical Connections

The module has been designed for spring-type terminal electrical connections.

Proceed as follows to make the connections:

1. Strip the cables by 0.8 mm
2. Insert a screwdriver in the square hole and press it until the cable lock spring opens.
3. Insert the cable in the round hole.
4. Remove the screwdriver and make sure that the cable is tightly fastened in the terminal.

Power supply
There are various ways to provide the K Series modules with power.

1. Direct power supply to the modules by connecting 24 Vdc power supply directly to Terminals 7 ( + ) and 8 ( – ) of each module.
2. Using the K-BUS connector accessory for the distribution of the power supply to the modules via bus connector, in this way eliminating the need to connect power supply to each module. The bus can be supplied from any of the modules; the total absorption of the bus must be less than 400 mA. Higher absorption values can damage the module. An appropriately sized fuse must be connected in series to the power supply.
3. Using the K-BUS connector accessory for the distribution of the power supply to the modules via bus connector and the K-SUPPLY accessory for the connection of the power supply. The K-SUPPLY accessory is a 6.2 mm wide module that contains a set of protections designed to protect the modules connected via bus against over-voltage loads.
   The bus connector can be provided with power using the K-SUPPLY module if the total absorption of the bus is less than 1.5 A. Higher absorption values can damage both the module and the bus. An appropriately sized fuse must be connected in series to the power supply.
