Omni8C - Remote Logic Unit, 8 Potential Free Contact Input annunciator no display. Display connected via ribbon cable.


The Omni8C RLU is a full function alarm annunciator logic module for 8 alarm points. Interconnect up to 16 modules together to produce an alarm annunciator up to 128 points. Connect to remote alarm displays such as the Omniflex Model C1670 or C1496 series Displays for a complete window alarm annunciator system, or wire to individual mimic lights to provide full critical alarm functionality to your mimic display. 

The 8 inputs accept potential free inputs and are individually “DIP” switch configured for N.O. or N.C. operation. 

Alarm Sequences 
The alarm sequence for the 8 inputs can be configured by DIP switch with a choice of 27 standard sequences. More individualised or advanced settings are done through the programming port accessible on the unit using the free Omniset Configuration Utility. 

Control Pushbuttons 
Test, Silence, Acknowledge and Reset Pushbutton input terminals are provided for a wide variety of control options. 

Group Alarm Functions 
The four common output relays can be configured as group alarm, horn output and watchdog. Functions such as Relay follows input or alarm, Multiple Re-flash, or Ring-back horn are easily settable on these relays. An Inhibit input function is provided which disables all 
the inputs on the annunciator, for example during plant startup or shutdown periods.
Optional Communications Serial Port 
An optional RS232/485 serial port can be fitted to allow all alarm functions to be accessed from your PLC or SCADA using the popular Modbus protocol. 

Optional High Power Lamp Driver Outputs 
A version of this product is available equipped with high power lamp drivers. These drivers can source 24Vdc up to 250 mA, with short circuit protection, to drive higher power mimic lights, or large alarm displays.
