I/O modules

The GE DS200TCEBG1A DS200TCEBG1ABC provides expanded termination capacity for Mark V turbine protective circuits. You can install this board into the main turbine control cabinet. It adds connection points for safety-related field devices. This board suits gas and steam turbine protection systems.

Technical Specifications and Hardware Layout

The GE DS200TCEBG1A DS200TCEBG1ABC measures 280 mm in height. Its width reaches 185 mm, and the depth equals 30 mm. The GE DS200TCEBG1A DS200TCEBG1ABC weighs approximately 0.41 kilograms. A single multilayer PCB holds all termination and isolation circuits. The board contains no energy storage capacitors or batteries. Two 50-pin ribbon connectors provide interface to the main control system. Three terminal blocks handle field wiring terminations. Six test points allow signal monitoring with a multimeter.

Termination Specifications and Protection

The GE DS200TCEBG1A DS200TCEBG1ABC provides 24 additional termination points for protective circuits. It accepts field wiring from emergency stop devices and safety interlocks. Each input includes a surge suppression diode for transient protection. Consequently, this board shields sensitive control circuits from voltage spikes. The board provides optical isolation between field wiring and the backplane. Individual LED indicators show the status of each termination point. The expander includes a ground terminal for shield connections.

Installation and Diagnostic Features

You must insert the GE DS200TCEBG1A DS200TCEBG1ABC firmly into a dedicated Mark V rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. Four front LEDs show power and termination status clearly. For troubleshooting, use the six test points with a multimeter. Always power off the system before removing or inserting the board. The operating temperature range spans from -20°C to +55°C reliably.
