Product Brief - Model C1423A Omni8/16C Annun Serial Interface Board

Omni8/16C Annun Serial Interface Board

picarrow Modbus Protocol - Slave
arrow Optional RTU or ASCII Modes
arrow Selectable Baud Rate
arrow Default Mode for easy access
arrow RS485 Address set on "DIP" switch
arrow Serial Interface (RS232/485) for Omni8/16C Annunciators

Omni8/16C Serial Interface RS232/485 using Modbus protocol for full Integral Annunciator variants ONLY. C1423A is used for full Integral Annunciators and C1423B used for Remote Logic Units.

The Modbus serial Interface options board allows the annunciator to become a Modbus slave device on RS232 or RS485 communications network.

This enables Omni8/16Cs to receive inputs serially instead of hardwired or for other serial devices to access the hardwired input status via the serial port. 

Up to 15 Omni8/16Cs be multi-dropped on an RS485 port and all data transmitted or acquired serially.

The serial Interface allows the annunciator to be used in a complimentary role with PLCs or SCADA. Using Modbus communication critical alarms can be routed from the SCADA to Annunciator forcing operator intervention as well as external audible and visual indication of alarms. In a similar way a PLC can be offloaded from the task of processing alarms by routing this function to the annunciator.
