Product Details：

Honeywell 51196653200 (51196653-200) is the upgraded version of 51196653100 switching power supply for Honeywell TDC3000 five-slot I/O chassis,its main purpose is stable multi-channel low-ripple DC power distribution for the backplane bus loaded with hybrid IOP boards and paddle interface boards. This power unit accepts 85-264VAC wide-range universal industrial AC input,adopts high-efficiency switching topology and optimized EMC filtering circuit design,greatly improving immunity against high-frequency interference from heavy industrial cabinet environment,reducing analog signal drift,trend jitter and random communication error caused by power noise. It outputs matched multi-rail DC voltage groups required by TDC3000 I/O backplane,including +5V,+12V,-12V and auxiliary supply rails,to power PLCI hybrid I/O boards,signal termination boards and backplane logic circuits. It has comprehensive protection logic including overvoltage,undervoltage,overcurrent,short-circuit and overtemperature lockout protection. When the backplane load short circuit or internal power component overheating occurs,it will cut off output rapidly and avoid fault cascading to other expensive I/O cards. It supports hot swap operation under lockout-tagout maintenance rules,minimizing downtime of critical continuous production control loops. It continuously monitors output voltage,load current and internal temperature,records timestamped fault events and uploads alarm messages to LCN operator stations for maintenance troubleshooting and replacement. It is a scarce original spare power part for legacy TDC3000 remote I/O subrack projects,perfectly matched with 51195499100 five-slot chassis and various TDC3000 IOP modules.

Key specifications：Rack plug-in power supply for TDC3000 five-slot I/O chassis,85-264Vac universal wide input,multi-channel regulated DC output,improved noise suppression performance. Operating temperature range is 0°C to +60°C. It supports overload,overheat,short circuit and input voltage anomaly fault diagnosis. The PCB is conformal coated for dust and moisture resistance. Front panel LED indicators display power ready status,load operating condition and fault warning for quick on-site inspection.

This five-slot chassis power supply module is widely deployed in petrochemical,chemical,power generation and water treatment plants for legacy TDC3000 DCS remote I/O subrack upgrade and maintenance projects. It cooperates with Honeywell PLCI I/O board,paddle board and LCN adapter board to build distributed Data Hiway I/O subrack. As a core unit for five-slot chassis power supply and rack backplane feeding,it is the upgraded stable power carrier for TDC3000 five-slot I/O subrack. Clearly marked power and backplane connectors simplify mains wiring,load testing and periodic power ripple verification work for control engineers.
