I/O modules

The GE DS200TCEAG1A DS200TCEAG1AFB performs turbine overspeed detection and emergency shutdown functions. You can install this board into the main turbine control cabinet. It monitors speed signals from magnetic pickup sensors. This board suits gas and steam turbine critical overspeed protection systems.

Technical Specifications and Hardware Layout

The GE DS200TCEAG1A DS200TCEAG1AFB measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCEAG1A DS200TCEAG1AFB weighs approximately 0.40 kilograms. A single multilayer PCB holds all speed monitoring and logic circuits. The board contains no energy storage capacitors or batteries. Two 50-pin ribbon connectors provide system interface connections. Two speed sensor inputs accept magnetic pickup signals. Four test points allow signal monitoring with an oscilloscope.

Overspeed Monitoring Specifications

The GE DS200TCEAG1A DS200TCEAG1AFB accepts speed signals from two independent magnetic pickups. It triggers an emergency shutdown at 110 percent of rated turbine speed. Response time from overspeed detection to output activation stays below 20 milliseconds. Consequently, this board provides critical overspeed protection for turbine applications. The board includes programmable overspeed setpoints via onboard jumpers. Two relay outputs activate the emergency trip solenoid in a redundant configuration. A built-in self-test circuit verifies board functionality during operation.

Installation and Diagnostic Features

You must insert the GE DS200TCEAG1A DS200TCEAG1AFB firmly into a dedicated Mark V rack slot. Transitioning to wiring, use shielded twisted-pair cables for speed sensor connections. Four front LEDs show power, speed status, and trip condition clearly. For testing, use a signal generator at the test points. Always power off the system before removing or inserting the board. The operating temperature range spans from -20°C to +55°C reliably.
