The Honeywell 10302/2/1 is a secure watchdog relay module designed specifically for FSC (Fail Safe Controller) systems. Its core function is to receive raw signals from the watchdog of the controller, enhance and distribute them to various output modules in the I/O rack.
- Watchdog repeater (WDR)
- The required watchdog current exceeds 900 mA
- The watchdog repeater requires a horizontal bus connection
At the hardware level, this module has extremely high electrical performance specifications and supports low-power operating modes of 5V DC (35mA) and 24V DC (25mA). It is designed specifically for complex power configurations, and when the FSC system contains multiple 24V to 5V power modules (such as PSU 2/3/4), 10302/2/1 is responsible for transmitting watchdog commands across power domains.

This module is required in the following specific FSC configurations:
Multi power system: When the system contains multiple 24V to 5V power modules (PSUs), this repeater is required.
Hybrid I/O architecture: When a system contains both redundant and non redundant I/O, it is responsible for generating necessary watchdog output signals for the non redundant parts.
High current load: When the required watchdog current exceeds the 900 mA threshold, this module needs to be installed to ensure driving capability.
