Description Product Introduction The UCN is the backbone of a TDC 3000 system—and it needs clean, reliable power. The 51404223-001 slides into a UCN power supply chassis and delivers 24 VDC to the network nodes and I/O. Run two in parallel for redundancy; if one fails, the other keeps the system alive without a glitch. What makes this power supply different from a standard industrial supply? It’s designed for hot-swapping in a live UCN. In my experience, that’s a huge advantage during maintenance—you can pull a failed supply and replace it while the process runs. The module has built-in diagnostics and reports its status back to the system. When the red Fault LED lights up, you know it’s time for a swap. Key Technical Specifications Parameter Value Model 51404223-001 Brand Honeywell Series TDC 3000 / UCN Product Type Redundant Power Supply Module Input Voltage 115/230 VAC selectable (or 24 VDC variant—verify) Input Frequency 47–63 Hz Output Voltage 24 VDC nominal Output Current 10 A (typical—check specific system requirements) Redundancy Supports 1 1 redundant operation Hot-Swappable Yes (in UCN chassis) Protection Overcurrent, overvoltage, short circuit Indicators Power OK (green), Fault (red), Current Share (if redundant) Diagnostics Status reporting to UCN node Cooling Convection (internal fan on some variants) Temperature Rating 0 °C to 55 °C operating Mounting UCN power supply chassis Certifications CE, UL, CSA Firmware / Software Versions & Upgrade Notes Here’s the straightforward part: the 51404223-001 is a power supply. No firmware. No software. No Firmware: The module uses analog control circuits. There’s nothing to flash or upgrade. Hardware Revision: Look for Rev 3 or later on the label. Earlier revisions had a known issue with the input filter capacitors—they would age faster in high-ambient environments. Rev 3 upgraded the capacitors and added improved transient protection. LED Behavior: Green OK LED = module working, output within spec Red Fault LED = input out of range, output overcurrent, or internal failure No LEDs = dead module or no input power Redundancy Operation: Two supplies run in parallel Current-sharing circuit balances load If one fails, the other takes full load immediately Replace failed unit without disturbing the system Compatibility: Works with all UCN nodes and I/O modules requiring 24 VDC power. Check your system voltage requirements before installing. Compatibility & Replacement Matrix Use this when maintaining TDC 3000 UCN power systems. Original Model Replacement Model Compatibility Level Key Notes 51404223-001 51404223-001 Drop-in Identical part. Direct replacement. 51404223-001 51404223-002 Needs Adaptation The -002 suffix may indicate a different input voltage (e.g., 125 VDC instead of AC). Verify system power before swapping. 51404223-001 51404222-001 Incompatible Different power supply series. Check your chassis compatibility. 51404223-001 Rev 2 51404223-001 Rev 3 Drop-in Later revision supersedes earlier. Improved capacitors and transient protection. Direct replacement. 51404223-001 Third-party 24 VDC supply Incompatible UCN chassis requires specific form factor and hot-swap capability. Generic supplies won’t fit or report status.
