Honeywell 900P02-0001 Power Supply Module

Honeywell 900P02-0001 Power Supply Module

The Honeywell 900P02-0001, also cataloged as the 900P02 switching power supply, serves as a dedicated hardware component for regulated DC distribution within ControlEdge HC900 systems.

Hardware Specifications

4–20 mA HART Loop Protocol & Channel Isolation

Although primarily a supply module, the 900P02‑0001 applies Honeywell’s isolation principles used in 4–20 mA HART loop environments. Independent regulation of 5 VDC and 24 VDC outputs ensures channel‑to‑channel isolation between CPU and I/O modules. This architecture stabilizes HC900 controller operation under varying load conditions and prevents interference across distributed process control loops.

Frequently Asked Questions

Q: Can the 900P02‑0001 be hot‑swapped? A: No, the module requires full de‑energization before insertion or removal to prevent undefined states.

Q: What is the maximum combined output power? A: The module provides up to 28 W total across 5 VDC and 24 VDC outputs.

Q: Is the module compatible with redundant HC900 configurations? A: Yes, it can be deployed in redundant rack architectures with dual supply modules for failover protection.

Field Installation Guidelines

• Mount the module in the designated HC900 rack slot with secure fasteners.
• Route AC input wiring separately from DC output cabling to minimize EMI.
• Verify polarity and insulation of 5 VDC and 24 VDC outputs before energizing.
• Ensure grounding of chassis and shield connections to maintain isolation integrity.
• Inspect connectors and terminals for contamination prior to installation.
