Description
The 10302/2/1 is a watchdog relay module in Honeywell's safety management system. It monitors, isolates, and amplifies watchdog signals within the system, ensuring that the communication link between safety system logic decisions and actuators remains under control.
Applications
Chemical plant: Extend watchdog signal transmission between cabinets, maintaining safe interlock communication across systems.
Refinery: Amplify watchdog signals from main controllers, driving remote reset switches in cracking unit cabinets.
Power plant: Isolate watchdog lines between control racks, preventing electrical interference in turbine protection systems.
Steel plant: Relay blast furnace explosion-proof watchdog pulses, preventing signal loss over long-distance cables.
Practical use
A watchdog repeater is required in the following cases:
in multiple-PSU configurations, for each subsequent 24 Vdc to 5 Vdc power supply unit, e.g. PSU 2, 3, 4.
if the 24 Vdc is supplied via an M24-20 HE or M24-12 HE power supply.
if the 24 Vdc is supplied via a power supply which can provide supply voltages that exceed 31.0 Vdc. (The maximum output
voltage of the 24 Vdc supply must be less than 37 Vdc under any single or double fault condition of the 24 Vdc power supply unit.)
