Structural Characteristics
Single-width 200 Series FBM form factor. Interfaces with the backplane via precision pins and connects to field transmitters through a specific Terminal Assembly.
Operating Principle
Receives analog current signals from field transmitters, conditions the signal, converts it to a digital value using high-precision A/D converters, and transmits the data to the controller over the redundant Module Fieldbus.
Installation Requirements
Mount on a compatible 200 Series baseplate. Ensure the control cabinet is well-ventilated and properly grounded. Use shielded twisted-pair cables for analog wiring to prevent noise interference.
Usage Precautions
Ensure the field transmitter output matches the module’s specified 0-20 mA input range. Avoid routing analog cables parallel to high-voltage power lines. Always observe standard ESD precautions during handling.
