GE IS200ECTBG2A IS200ECTBG2ADE Exciter Terminal Board

The GE IS200ECTBG2A IS200ECTBG2ADE Exciter Contact Terminal Board manages field excitation contacts for turbine generators. You will find this board critical for reliable synchronizing operations. Its design prioritizes high-density relay control in Mark VI IS200 systems.

Dimensions, Weight, and Mechanical Layout

This exciter contact terminal board measures 22.5 cm in length and 15.3 cm in width. Its height reaches 3.1 cm including terminal blocks and relays. The total weight stands at 0.78 kilograms for secure DIN-rail mounting. A rugged fiberglass-reinforced PCB withstands high vibration environments.

Relay Interfaces and Component Count

The GE IS200ECTBG2A IS200ECTBG2ADE Exciter Contact Terminal Board provides 12 independent electromechanical relays. Each relay supports 250V AC or 30V DC at 5 amperes. You also get 6 dry contact inputs for external status monitoring. In total, this exciter board contains 203 individual electronic components. These include 12 relays, 4 optocouplers, and 142 ceramic capacitors.

Energy Storage and Power Parameters

A 3.3V supercapacitor array provides onboard energy storage for 36 hours. This backup preserves relay states during short power interruptions. The board draws only 4.5 watts from a nominal 24V DC supply. Peak inrush current stays safely below 2.0 amperes.

Memory, Processing, and Environmental Limits

You get 32 MB of flash memory for contact logic configuration storage. An 80 MHz dedicated microcontroller handles all relay timing sequences. Therefore, the operating temperature ranges from -30°C to +65°C. Storage temperatures extend from -40°C to +85°C without performance loss.

Connectors, Wiring, and Additional Features

Two 40-pin ribbon cable headers connect to the main control board. A single 10-pin screw terminal block accepts 12–24 AWG field wiring. For similar static trip excitation control, see the RMS-TSG-TZ-C model from the same manufacturer. However, this exciter contact terminal board focuses purely on generator field switching. Mean time between failures (MTBF) exceeds 100,000 hours in continuous operation.
