GE DS200RTBAG3AFB

Technical Specifications: Relay coil rated voltage: 115 V AC; onboard relay quantity: 10; terminal connector quantity: 52 screw‑locking connectors; adapt to Mark V system rack installation; operating temperature: 0 °C ~ +60 °C; PCB material: industrial high‑temperature resistant circuit board; conform to gas‑turbine control industrial standards.

Functional Features: On‑board relay output control; field‑site signal wiring terminal integration; signal filtering and surge suppression; electrical isolation between field circuit and control system internal circuit; screw‑locking reliable wiring; fault status feedback transmission; plug‑in compatible with Mark V system rack; support remote drive of ground‑relay equipment.

Application Scenarios: Gas turbine and steam turbine control cabinet; power‑generation unit Mark V control system; oil‑and‑gas heavy‑duty turbine equipment; power‑plant turbine protection and auxiliary control circuit; industrial large‑size prime‑mover control system retrofitting and maintenance.

Performance Parameters: Each relay supports 115 V AC coil drive; terminal screw‑locking structure ensures anti‑loose connection under vibration environment; signal isolation capability meets turbine‑control EMC requirements; long‑term stable operation under cabinet vibration and temperature‑cycling conditions; each connector supports multi‑strand industrial control wire connection.

Material Composition: Circuit substrate: high‑Tg industrial‑grade FR‑4 PCB; onboard relays: industrial‑grade AC electromagnetic relays; connectors: metal screw terminals with flame‑retardant plastic base; gold‑plated back‑plane contact pins; metal positioning hardware; surface‑mount surge‑suppression components.

Structural Characteristics: Rectangular standard rack plug‑in board structure; back‑end gold‑finger for system back‑plane connection; front‑end dense‑arranged screw‑type terminal connectors; onboard multiple relay components distributed on PCB surface; metal positioning screws for fixing inside cabinet; silk‑screen mark for each signal terminal on board surface.

Working Principle: Receive control logic signal transmitted by Mark V system mainboard through back‑plane gold‑finger; drive corresponding onboard relay to pull‑in or release; relay contacts switch external field‑site circuit; field‑site input signal is connected via screw terminals, filtered and isolated on board and transmitted back to system mainboard, completing signal bidirectional conversion between control system and field‑site equipment.

Installation Requirements: Power‑off state before installation and disassembly; insert the board into the designated slot of Mark V control rack, fasten fixing screws; mark each external wire before disassembly; strictly correspond wiring to silk‑screen signal definition; ensure cabinet ground‑wire connection is reliable; keep board surface away from metal debris; maintain cabinet ventilation and heat‑dissipation condition.

Usage Notes: All wiring operations must be completed under power‑off condition; strictly distinguish AC relay‑coil circuit and low‑voltage control signal circuit; prevent metal screw and washer from dropping into cabinet inner cavity; regularly check terminal screw tightness under vibration environment; prohibit operation beyond working‑temperature range; avoid corrosive gas and heavy dust accumulation; static‑protection wrist‑strap shall be worn during maintenance and replacement.
