Honeywell 05701-A-0325 DC Input Card

Product No.: 05701-A-0325
Manufacturer: Honeywell

The 05701-A-0325 is a DC Input Card designed to provide centralized and protected power input for a Honeywell control system rack. It plays a critical role in powering all other modules within the sub-rack, ensuring stable and reliable power delivery for essential process control and safety applications. This card is built to offer robust protection, power management, and redundancy features.

Key Features

• Centralized Power Input
  Serves as the main entry point for a nominal 24V DC power supply, distributing power to all modules in the rack via the backplane.

• Integrated Protection
  Equipped with a fuse to protect the sub-rack from excessive current, safeguarding the entire control system.

• Reverse Polarity Protection
  Prevents system damage if the power supply connections are incorrectly made, ensuring safe and reliable operation.

• RFI Filtering
  Provides Radio Frequency Interference (RFI) filtering to ensure clean power delivery and prevent external noise from affecting the performance of the system.

• Dual Power Inputs
  Supports both a main power supply (PSU) and an auxiliary backup battery supply (AUX), ensuring redundancy for continuous operation.

• Diode Isolation
  Isolates the PSU and AUX connections with diodes, preventing faults in one supply from affecting the other and enabling seamless backup power operation.

• Easy Maintenance
  Includes a two-part terminal block (TB1) that allows for easy removal of the card without needing to disconnect individual wires, simplifying maintenance and reducing downtime.

• Flexible Power Configuration
  Offers recommendations for alternative power configurations for large systems (e.g., those with more than eight 5704 Catalytic Cards) to prevent excessive current flow along the backplane.
