      Features:

      • Watchdog Repeater (WDR) Module
      • Monitors the 5 Vdc and 24 Vdc supplied to the I/O modules
      • Watchdog repeater is required if the required watchdog current exceeds 900 mA
      The watchdog repeater is used to monitor the 5V and 24V DC power supply for I/O modules. The watchdog output of the watchdog repeater connects to the watchdog input of the monitored power supply (5V and/or 24V DC) output module.The watchdog repeater requires a horizontal bus connection. This means that space must be reserved in the I/O rack (positions 1, 2, 11-18).

      The watchdog repeater must always be placed in the I/O section containing the output module it monitors. This means that in configurations with multiple (redundant) I/O sections, the watchdog repeater must not be installed in a way that allows it to control “other” I/O sections.

      The 10302/2/1 Honeywell Watchdog Repeater (WDR) Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      Honeywell 10302/2/1 Watchdog Repeater (WDR) Module Manuals(Datasheets), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      The watchdog repeater can be replaced while powered on, but the central unit will be turned off; if used in a configuration with redundant central units and non-redundant I/O, both central units will be turned off.
      Safety-Critical Monitoring: As a safety mechanism, it monitors system failures and restarts the system upon detection.
      Multi-Power Supply Unit Configuration: In setups with multiple power supply units (e.g., power supply units 2, 3, or 4), this configuration is required for each subsequent 24Vdc to 5Vdc unit.
      Redundant I/O System: Crucial in configurations using a mix of redundant and non-redundant I/O to create watchdog outputs for non-redundant modules.
      Voltage Failure Protection: This protection is required when the 24Vdc supply voltage may exceed 31.0Vdc or the watchdog current exceeds 900mA.
