The GE IS200TPIMG1A IS200TPIMG1AAB protective interface terminal board connects safety circuits to Mark VI systems. This board provides a secure interface between protective relays and the main controller. You will find this terminal board in Speedtronic Mark VI protection panels. Its rugged design ensures reliable operation in critical safety circuits.
Protection Interface Architecture
This protective terminal board provides forty screw terminal connections for safety wiring. Consequently, you can connect multiple protection devices without additional hardware. The GE IS200TPIMG1A IS200TPIMG1AAB 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 Safety Wiring
The unit includes metal-oxide varistors across each terminal channel. Therefore, it clamps voltage spikes and protects downstream electronics. This board replaces the IS200TPIMG1AAB version without any wiring changes. Simply remove the old board and install this one. GE designed this terminal board 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 IS200TPIMG1A IS200TPIMG1AAB 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 control systems in lightning-prone areas.
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 IS200TPIMG1A IS200TPIMG1AAB works with all GE Mark VI protection I/O boards. 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 board includes two configuration jumpers for signal type selection. The GE IS200TPIMG1A IS200TPIMG1AAB simplifies protection circuit wiring for turbine systems. Installation requires only a flathead screwdriver for terminal connections. This board operates reliably in non-condensing environments with adequate clearance.
