The GE IS200TBCIH2B IS200TBCIH2BBC terminates discrete contact signals from field devices. This board accepts dry contact inputs from switches and relays. It fits directly into GE Mark VIe and EX2100 control systems. You will use this unit for status monitoring and limit detection.
Technical Specifications Overview
This contact input terminal board provides 32 isolated channels for dry contacts. Each channel senses open or closed states with a 24 V DC wetting voltage. The GE IS200TBCIH2B IS200TBCIH2BBC scans all inputs every 2 milliseconds. A built-in debounce filter eliminates false triggers from contact chatter. Consequently, you receive clean and reliable status data for your logic solver.

Internal Components and Energy Storage
The GE IS200TBCIH2B IS200TBCIH2BBC contains one main PCBA with 148 discrete components. Key parts include 32 optocouplers and 32 current-limiting resistors. The board also holds two electrolytic capacitors storing 330 µF of energy. This storage maintains input sensing during 5 ms power interruptions. Moreover, a shift register IC serializes all channel data for the backplane interface. Each input includes a transient suppression diode for surge protection.
Physical Interfaces and Connectors
You will find one rear-facing 40-pin connector on this board. This connector links to the Mark VIe backplane for data transfer. Thirty-two front-facing screw terminals accept field wiring from switches. A separate 2-pin header provides optional external wetting voltage input. Four green LEDs indicate power status and backplane communication. One red LED lights for any internal board fault. Six mounting holes secure the GE IS200TBCIH2B IS200TBCIH2BBC firmly to its chassis.
Installation and Operational Reliability
Install this contact input board inside a clean and dry cabinet. Maintain 30 mm of space above for wire access and bending. The board requires no user calibration or field adjustment. Therefore, you save commissioning time on every installation. This unit supports continuous operation in power generation and industrial facilities.
