10302/1/1 PLC Module Honeywell

10302/1/1 Watchdog Repeater: Essential Power Monitoring Module

Module Overview & Core Function

• Primary Function: The module monitors 5 Vdc and 24 Vdc power supplies to connected I/O modules.
• Watchdog Output: It provides a watchdog output signal to the watchdog inputs of monitored output modules.
• System Configuration: Essential in systems with multiple power supply units (PSUs) or mixed redundant/non-redundant I/O parts.
• International Approvals: The 10302/1/1 carries CE, TÜV, and UL certifications for global use.

Detailed Electrical Specifications

• Module Power Consumption: Requires 5 Vdc at 35 mA and 24 Vdc at 25 mA for operation.
• Watchdog Input: The WDG1 and WDG2 inputs each draw 0.1 mA monitoring current.
• Output Capacity: The WDR OUT provides maximum output current of 900 mA to drive watchdog circuits.
• Voltage Monitoring: Specifically designed to monitor standard 5V and 24V DC I/O power rails.

Physical Design & Key Coding

• Mounting Size: Compact design requires 4 TE, 3 HE (4 HP, 3U) of rack space.
• Module Key Code: Configured with holes at position A27 and pins at C11, C23, C27.
• Rack Key Code: Corresponding rack requires blind spots at C3, C19, C31 and large pins at A27.
• Bus Connection: Requires horizontal bus connection in standard I/O rack positions 1 through 18.

Frequently Asked Questions (FAQ)

• What does the 10302/1/1 module actually monitor?
  It continuously monitors the 5 Vdc and 24 Vdc power supplies that power your system's I/O modules.
• When is this watchdog repeater required?
  It's essential in systems with multiple PSUs, specific power supply types, or redundant I/O sections.
• What is the maximum output current capability?
  The watchdog output can supply up to 900 mA to connected modules' watchdog inputs.
• Can I replace the module while the system is running?
  Yes, it's hot-swappable, but may trigger a Central Part shutdown during exchange.
• What is your shipping and return policy?
  We ship within 5 days via major carriers and offer a 30-day return policy.
