The GE IS200ECTBG1A IS200ECTBG1ACB exciter terminal card connects field wiring to Mark VI excitation systems. This card provides a secure interface between exciter field devices and control modules. You will find this terminal card in GE Mark VI exciter control cabinets. Its rugged design ensures reliable operation in demanding excitation applications.
Termination Architecture
This exciter terminal card provides forty screw terminal connections for field wiring. Consequently, you can connect many exciter sensors and contactors without additional hardware. The GE IS200ECTBG1A IS200ECTBG1ACB includes built-in surge suppression on each channel. Moreover, clearly marked terminals simplify wiring and troubleshooting. You can terminate wires quickly using standard slotted screwdrivers.

Surge Protection and Field Wiring
The unit includes metal-oxide varistors across each terminal channel. Therefore, it clamps voltage spikes and protects downstream electronics. This card replaces the IS200ECTBG1ACB version without any wiring changes. Simply remove the old card and install this one. GE designed this terminal card for single-slot installation. Hence, it fits directly into existing Mark VI rack positions.
Four PCB layers separate field wiring traces from backplane signals. Two connectors handle all signal and ground connections. The GE IS200ECTBG1A IS200ECTBG1ACB includes a dedicated ground bar for surge current return. Accordingly, it safely diverts transient energy away from sensitive circuits. This feature proves essential for protecting exciter controls in harsh environments.
Installation and Wiring Guide
You can terminate both stranded and solid copper wires securely. The screw clamps accept wires without special ferrules or lugs. The GE IS200ECTBG1A IS200ECTBG1ACB works with all GE Mark VI exciter I/O modules. Always strip 6-8 mm of insulation before inserting wires. Proper torque on terminal screws prevents loose connections over time.
Each MOV provides bi-directional surge protection for AC and DC circuits. The card includes two configuration jumpers for signal type selection. The GE IS200ECTBG1A IS200ECTBG1ACB simplifies exciter field wiring for turbine systems. Installation requires only a flathead screwdriver for terminal connections. This card operates reliably in non-condensing environments with adequate clearance.
