ABB SDCS-CON4-COAT DCS spare parts control processor module

Description

SDCS-CON4-COAT 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 SDCS-CON4-COAT components from field outputs. Power from the external power

supply is used to power the loads connected to the contacts.

SDCS-CON4-COAT 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
