Product:Honeywell 10005/1/1 Watchdog module (WD) Tested before shipping

The watchdog module monitors system parameters including: • the application loop maximum execution time in order to detect if the process is executing its program correctly and is not looping (hang-up). • the application loop minimum execution time in order to detect if the processor is executing its program correctly and is not skipping program parts. • 5 Vdc voltage monitoring for overvoltage and undervoltage (5 Vdc ± 5 %). • memory error logic from CPU, COM and MEM modules. In case of a memory error, the watchdog output is de-energized. • ESD input to de-energize the watchdog output independently from the processor. This ESD input is 24 Vdc and galvanically isolated from the internal 5 Vdc.
