Document Overview

The purpose of t his Quick St art Guide (QSG) is t o acquaint t he user wit h t he F4T/ D4T High Density (HD) Flex Modules and associated wiring.

Product Overview

Flex modules serve as t he interface bet ween real-world devices and t he F4T/ D4T system. The flex modules described in t his document offer various input and out put opt ions and greater density (more than 1) than the standard flex modules. With the except ion of t he Dual SSR module, all of these modules can be placed in any available slot.

Installation and Wiring

To install the flex module:

1. Note the part number to determine the number and type of inputs or outputs available to be connected in step 7.
2. Turn off device power.
3. Select a compatible base slot for the module. See the Flex Module-Slot Dependencies table below. If replacing a module, remove the old module.
4. Affix corresponding slot number labels (provided) to the module and to the removable screw terminal block.
5. With the component side of the module facing right (viewing the F4T/D4T from the rear) insert the module into the slot until it latches.
6. Remove the screw terminal block from the module.
7. Wire field devices to the appropriate terminals. Wiring details for each input and output are provided in the following sections.
8. Reconnect the wired screw terminal block to the module. Be sure to reconnect the terminal block to the correct module.
9. Restore power to the F4T/D4T.

Note:
If the flex module is a replacement with the same part number and slot position, the F4T/D4T uses it immediately when powered up. Otherwise, use Composer software to configure the F4T/D4T to expect and use the module.

Module Characteristics

Description and Identification

Many of the modules appear to look alike at first glance, therefore, it is always recommended that the module part number be verified prior to plugging it into any of the available slots in a base. Each module is identified with a part number located on the back side of the assembly next to the screw terminal block, as displayed in the graphic to the right.

Wiring
Prior to wiring any of the I/O modules described in this document, it is recommended that the warnings and notes listed below be reviewed.

CAUTION:
To prevent damage to the F4T/D4T, do not connect wires to unused terminals.

Note:
Maintain electrical isolation between the analog input, digital input-outputs, switched dc/open collector outputs and process outputs to prevent ground loops.

Note:
Modules IP10 when properly installed in base enclosure with slot caps in empty slots.

CAUTION:

Switching pilot duty inductive loads (relay coils, solenoids, etc.) with the mechanical relay, solid-state relay or open collector output options requires use of an R.C. suppressor for AC load or a diode for a DC load.

Note:
Wire size and torque for screw terminations:

• 0.0507 to 3.30 mm² (30 to 12 AWG) single-wire termination or two 1.31 mm² (16 AWG)

• 0.57 Nm (5.0 lb.-in.) torque
