Description

1. Basic Info

Part No: 3A59347G01
Manufacturer: Westinghouse (later acquired by Emerson Automation)
Type: Q-Line FO Remote I/O Node Complete Cage Assembly, integrated backplane + built-in rack power supply, equipped with factory pre-mounted backplane 4256A99G02 & interface board 1D54557G10
System Match: Classic WDPF DCS Q-Line distributed remote I/O system, widely used for thermal power plant boiler/turbine field remote IO cabinet
Availability: Original OEM production discontinued; available goods: refurbished tested unit / used original spare; professional repair service available (2~4 weeks standard turnaround)

2. Electrical Parameter

  • Input: AC 85~264V wide-range mains input

  • DC Output: +5V, +12V, -12V multi-channel regulated DC for backplane I/O cards total rated 40W

  • Protection: Full OVP overvoltage, OCP overcurrent, short-circuit lockout, overheat auto shutdown, built-in EMI filter

  • Working Temp: 0℃ ~ +55℃ operational; -40℃ ~ +85℃ storage, comply with CE & UL industrial certification

3. Core Function

  1. Complete Q-Line remote IO rack base unit: holds multiple discrete/analog I/O modules, backplane realizes internal bus signal routing & power distribution for all slot cards

  2. FO fiber-optic bus interface via onboard 1D54557G10 circuit: fiber communication between local remote I/O node and central DPU controller, long-distance anti-interference field transmission

  3. Collect all slot module fault signals, upload alarm information to DCS main control via fiber bus, trigger system HMI fault alert

  4. Modular hot-swap design: single I/O card replacement without shutting down entire remote rack power supply

4. Application Field

Coal-fired power plant, combined-cycle power station, petrochemical plant WDPF Q-Line field remote IO cabinet retrofit & maintenance spare parts

5. Version Remark

G01 is the first official release revision of this Q-cage assembly, compatible pin-to-pin with later G02/G03 updated variants for field replacement.
