The Field Interface Module (FIM) for Analog Output (AO) signals is useful for interfacing 0- +/-10V or 0/4-20mA Analog Output Signals from PLC AO modules with the field devices.

The FIM consists of multiple (4 nos. or 8 nos.) AO type Analog Signal conditioning & Isolation modules mounted on a board. Different module types are available to interface PLC AO signals such as 0-+/-10V, 0-20mA & 4-20mA.

These modules perform the function of Isolation and duplication of the AO Signal so as to generate a calibrated and linearly proportional 0-+/-10V, 0-20mA, or 4-20mA output signal for field devices.

The use of CAN-AO FIM provides the advantage of Channel to Channel Isolation between Analog Output signals on the field side without loss of key performance parameters such as accuracy and response time.

The connection with Field Signals is provided with Phoenix type screw connectors. PLC side connections are also provided with Phoenix type screw connectors. Customized designs using D-sub connector on PLC side can be available to allow ease of connections using Prefab cables. The FIM is housed in a profile suitable for mounting on 35 mm std. DIN rail.
