Description

Hardware & Electrical Specifications

• Model：IS200DTAIH1ACC
• Part Number：IS200DTAIH1ACC
• Module Type：Simplex Analog‑Input‑Output Terminal Board
• Mounting：Plastic bracket, DIN‑rail installation inside turbine control cabinet
• Power supply：Auxiliary 24 V DC supplied by system rack
• Analog Input：10 channels, configurable 0‑10 V / 4‑20 mA via jumper setting
• Analog Output：2‑channel 0‑20 mA standard output; one channel supports jumper‑modification to 0‑200 mA
• Connector：JR1 37‑pin locking connector (interconnect with I/O core board via ribbon cable)
• Terminal block：TB1 48‑position screw terminals; terminal 43‑44 assigned for SCOM signal common ground
• Jumper resources：Total 21 groups jumper switches for channel signal‑mode configuration
• PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance
• On‑board protection：ESD protection, surge suppression, RC filter circuit for field signal loop
• Compatibility note：Cannot run standalone; must pair with corresponding Mark VI analog I/O core board; pin‑to‑pin compatible with IS200DTAIH1ABB, but jumper configuration must be fully restored after replacement to avoid signal fault or hardware damage。

Mechanical Data

• Weight：approx 1.20 kg
• Dimension：200 mm × 145 mm × 55 mm
• Handling note：ESD‑sensitive printed circuit board, anti‑static wrist‑strap operation mandatory
• Recommended wire cross‑section：0.75‑2.5 mm² shielded twisted‑pair copper cable for field‑side signal wiring
• Terminal tightening torque：0.6‑1.0 N·m

Main Functions

1. Terminate field analog signals from pressure, flow and other process transmitters via screw terminals.
2. Route field analog‑input signals to matched I/O core board through 37‑pin ribbon‑cable connection.
3. Convert analog output signals from controller board into field‑side current‑type control signals for actuators.
4. On‑board jumpers configure each channel for voltage‑mode or current‑mode according to site field‑device type.
5. Provide dedicated SCOM common‑ground terminals for field‑cable shielding connection.
6. Built‑in filter and surge‑suppression circuit to improve anti‑interference performance for long‑distance field wiring.
7. On‑board hardware channel diagnosis for over‑range, short‑circuit fault detection.
8. LED status indication:
   • Green LED：Terminal‑board auxiliary power supply normal
   • Yellow LED：Signal‑channel active status
   • Red LED：Field‑channel short‑circuit / over‑range 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 AI/AO channel value, confirm no short‑circuit fault before commissioning.
7. Replacement note: Hardware pin‑to‑pin compatible with IS200DTAIH1ABB, but jumper setting must be reproduced; full‑channel function test is mandatory after swap.
