Description
Module Operation
After checking the Board ID and verifying that the module is receiving appropriate logic power
from the Bus Interface Unit (as reflected by the state of the module’s Power LED), the Bus
Interface Unit then sends output data to the module in serial format. During transmission, the
module automatically loops this data back to the Bus Interface Unit for verification.
Serial to parallel converters convert this data into the parallel format needed by the module.
Opto-isolators isolate the module’s logic components from field outputs. Power from the
external power supply is used to power the loads connected to the contacts.
Field
Maximum Load Rating
The resistive rating of the module is 2 amps per point at 120/240 VAC or 24 VDC and 0.2
amps per point for 125 VDC. Power to energize the relay coils is supplied by the module.
An RC snubber is used across the contacts.
Suppression
Each output is suppressed with an RC snubber to reduce high frequency noise transients.
Proper suppression of the switched load is still recommended and will contribute to
improved system reliability. Suppression at the load will not only lengthen contact life, but will also
reduce noise transients in the control wiring
