System Monitor Module

The System Monitor Module is designed to distribute and monitor the 24VDC supply to each module within a 19" rack, and marshal the four common alarm signals - common fire, common fault, card removed, and card isolated.

In the unlikely event of a short circuit within the system or in the field circuit, the System Monitor module isolates either the module supply or the field 24V supply, whilst simultaneously raising the common fault audible & visual alarms. Each System Monitor Module monitoring each rack in this way allows the other racks in the system to continue operating independently, thus increasing the integrity of the system.
