GE DS200ADGIH1AAA Auxiliary Interface Board

Description

Hardware & Electrical Specifications

‑ Model: DS200ADGIH1AAA ‑ Part Number: DS200ADGIH1AAA ‑ Module Type: Mark V Auxiliary Interface PCB Board ‑ Mounting: Screw‑fastened installation inside Mark V control cabinet ‑ Connectors:  • 1 × 40‑pin field‑wiring connector  • 1 × 6‑pin system back‑plane connector ‑ Configuration hardware: 60 on‑board jumpers for channel mode configuration ‑ Diagnostics resources: Multiple on‑board test points for circuit measurement and troubleshooting ‑ Signal functions: Analog & discrete signal buffering, level translation, galvanic isolation ‑ Power supply: Powered from Mark V system rack back‑plane ‑ Isolation: Channel‑to‑channel and field‑to‑logic circuit isolation ‑ PCB treatment: Standard industrial conformal‑coated circuit board ‑ Compatibility note: Strictly for GE Speedtronic Mark V platform, not directly drop‑in compatible with Mark VI / Mark VIe. After replacement, verify all jumper positions match original unit, check connector tightness, perform signal‑loop testing via board test‑points, validate field‑device feedback and controller I/O status.

Mechanical Data

‑ Board dimension: 203.2 mm (8 in) width × 152.4 mm (6 in) length ‑ Mounting: Four‑screw fixed mounting onto cabinet card rack ‑ Weight: approx 0.48 kg

Main Functions

1. Acts as auxiliary signal‑conditioning interface between Mark V main control logic and field‑installed sensors, limit‑switches, solenoids and transducers. Performs signal buffering, level shifting and electrical isolation to suppress plant‑site electromagnetic interference.
2. 60 hardware jumpers allow on‑site hardware‑mode configuration for different signal‑types without modifying other system boards. Multiple test‑points support on‑site maintenance measurement and fault‑isolation.
3. No on‑board LED indicators; status observation must be completed via controller diagnostic displays and board test‑point measurements.

Installation & Wiring Requirements

1. Cut off complete rack power supply before installation or replacement. Non‑hot‑swappable. Strict ESD protection (wrist‑strap required) during board handling.
2. Secure DS200ADGIH1AAA onto cabinet rack with four mounting screws. Verify jumper‑setting positions are exactly consistent with original board configuration. Secure 40‑pin field‑wiring connector and 6‑pin system‑bus connector.
3. Field wiring must follow Mark V system‑wiring drawings. Reliable protective earth connection for control cabinet is mandatory.
4. After replacement: Restore rack power supply. Verify controller I/O status readings. Use on‑board test‑points to cross‑check field‑signal levels. Confirm interlock, protection and control‑loop function.
5. Replacement note: Jumper mis‑configuration will cause signal‑malfunction or false turbine trips. Full‑system commissioning and protection‑logic verification test is mandatory before putting turbine control into service.
