An Inhibit input function is provided which disables all
the inputs on the annunciator, for example during plant
startup or shutdown periods.

all alarm functions to be accessed from your PLC or
SCADA using the popular Modbus protocol.

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.
