Description
Product Overview
The IS400TBCIS2C Contact Input Terminal Board from GE is designed for high-integrity signal acquisition in Mark VIe control systems. It accepts 24 dry contact inputs through two barrier-style terminal blocks and includes group isolation for enhanced safety.
This board supports simplex, dual, and TMR configurations. It connects to I/O packs via JR1, JS1, and JT1 connectors depending on system redundancy. The board features noise suppression circuitry to protect against surge and high-frequency interference.
Installation is straightforward with removable terminal blocks and side-mounted brackets for I/O packs. The board uses JE1 and JE2 plugs to connect to the excitation voltage source.
