Description

Hardware & Electrical Specifications

• Model：IS200DTAOH1ABA
• Part Number：IS200DTAOH1ABA
• Module Type：Simplex Analog‑Output Terminal Board
• Mounting：Plastic bracket, DIN‑rail installation inside turbine control cabinet
• Power supply：Auxiliary 24 V DC from system rack
• Analog Output：8 channels, configurable 0‑10 V / 4‑20 mA via on‑board jumpers
• Connector：JR1 37‑pin locking connector (interconnect with analog‑output core board via ribbon cable)
• Terminal block：TB1 screw‑type field‑wiring terminals, dedicated SCOM signal common‑ground terminals
• Jumper resources：Multiple groups of jumper switches for each channel signal‑mode selection

• Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Receive analog‑output control signals from Mark VI I/O core board via 37‑pin ribbon‑cable interface.
2. Route and condition analog regulating signals, output 4‑20 mA / 0‑10 V signals to field actuators, valve positioners and I/P converters.
3. On‑board jumpers configure each output channel for voltage‑mode or current‑mode according to site field‑device requirement.
4. Provide dedicated SCOM common‑ground terminals for field cable shielding connection.
5. Built‑in filter and surge‑suppression circuit to improve anti‑interference performance for long‑distance field wiring.
6. Hardware channel diagnosis: detect output loop open‑circuit, short‑circuit fault, report fault status to controller.
7. LED status indication:
   • Green LED：Terminal‑board auxiliary power supply normal
   • Yellow LED：Output‑channel active status
   • Red LED：Field‑loop short‑circuit / open‑circuit fault alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Must perform anti‑static protection when handling PCB assembly.
2. Secure plastic DIN‑rail bracket firmly; ensure JR1 37‑pin connector fully locked without loose contact.
3. Restore on‑board jumper configuration strictly consistent with original settings before connecting field wiring.
4. Field wiring uses shielded twisted‑pair cables; separate analog signal cables from high‑power cables to reduce electromagnetic interference; connect shield to SCOM terminal with shortest wire length.
5. Complete protective grounding according to GE Mark VI Speedtronic system specification.
6. After replacement: double‑check jumper positions, verify each AO channel output value, confirm no short‑circuit fault before commissioning.
7. Replacement note: Jumper setting must be reproduced exactly as original; full‑channel output function test is mandatory after swap.
