The Omni16C Serial Display Product Range provides an easy-to-use alternative to providing Alarm Window facilities from your PLC, DCS or SCADA system. Each of these products has a fully isolated RS232/RS485 serial interface that provides full control of up to 16 alarm and status windows.

Up to 32 of these displays may be multi-dropped on a single RS485 twisted pair, providing up to 512 Window Status and Alarm display points from a single serial port acting as a Modbus Master. Each Display serial port acts as a Modbus slave, and can be set to either ASCII or RTU mode at baud rates from 300 to 9600 baud. Display options include incandescent lamps, backlit LED and Sidebar LED indicator windows to provide the user with the best combination of power consumption, reliability, maintenance and cost for the application. 27 integrated alarm flashing sequences included in the display remove the need for programming of alarm sequences in the PLC/DCS reducing engineering charges and program space, while increasing reliability.

Optional integral Test, Silence, Acknowledge, Reset Pushbuttons allow Operator alarm acknowledgment without any additional programming. Four optional output relays can be configured as group alarm, horn output and watchdog outputs.
