GE IS200ECTBG2A IS200ECTBG2ADE | Exciter Contact Board

Dedicated Contact Termination for GE EX2100 Systems

The GE IS200ECTBG2A IS200ECTBG2ADE terminates all exciter contact inputs and outputs. This terminal board belongs to the Mark VI series from General Electric. It handles dry contact signals from field devices exclusively. Therefore, it provides a clean interface for status monitoring and command outputs.

Physical Dimensions and Mounting Specifications

This terminal board measures 20 cm in width, 15 cm in height, and 3.5 cm in depth. The GE IS200ECTBG2A IS200ECTBG2ADE weighs approximately 0.47 kg, which supports stable panel mounting. Its compact footprint saves valuable cabinet space. Consequently, you can install it alongside other termination boards without crowding.

Connector Layout and Component Configuration

The GE IS200ECTBG2A IS200ECTBG2ADE features two 34-pin ribbon cable headers for rack interface. It also provides twenty 2-pin screw terminal blocks for contact wiring. This board contains twenty opto-isolator circuits for input protection. Additionally, it includes four energy storage capacitors for output relay holding.

Energy Storage and Signal Isolation Performance

The GE IS200ECTBG2A IS200ECTBG2ADE stores energy for output relay stability. Its four capacitors provide 1,880 µF of total capacitance. This storage prevents contact chatter during power fluctuations. Furthermore, the opto-isolators provide 2.5 kV isolation between field contacts and rack logic.

Role Within the EX2100 Excitation System

You will typically find the GE IS200ECTBG2A IS200ECTBG2ADE mounted near the customer connection panel. It connects to the main rack via two shielded ribbon cables. Moreover, this board handles both input and output contact signals. Its twenty terminal blocks accept wiring from pushbuttons, limit switches, and relay coils.

Installation and Contact Wiring Guidelines

Use the GE IS200ECTBG2A IS200ECTBG2ADE as a direct replacement for older ECTB revisions. Always verify the contact voltage rating before connecting any wires. This terminal board requires an external 24 VDC supply for wetting inputs. It needs no configuration jumpers or special tools. Simply secure the board with four mounting screws and connect your contact wires to the appropriate blocks.
