Product Overview
This terminal circuit board accepts dry contact inputs from field switches and sensors. You can connect GE IS200TBCIH1B IS200TBCIH1BCE directly to GE Mark VIe digital input cards. The unit monitors sixteen independent contact channels without requiring external wetting power. Each channel detects open or closed states with high noise immunity.

Board Layout and Components
The PCB arranges sixteen input channels in two rows of eight. Each channel includes a dedicated optoisolator for complete galvanic isolation. Additionally, 98 discrete components provide signal conditioning and contact debouncing. An internal 12V supply delivers wetting voltage to each dry contact pair. Consequently, you avoid using external power sources for simple switch monitoring.
Installation Process
You can mount GE IS200TBCIH1B IS200TBCIH1BCE on a standard 35 mm DIN rail. The 50-pin ribbon cable connects directly to the Mark VIe digital input card. Furthermore, each screw terminal accepts 16–24 AWG solid or stranded copper wire. Clearly numbered channel labels simplify wiring verification during initial setup.
Performance Advantages
The board applies a fixed 3 ms hardware debounce filter to every input. Therefore, mechanical contact bounce cannot generate false state changes. Each optoisolator provides 1500V RMS of isolation protection for safety. The passive design also draws minimal current from the system backplane.
Safety and Compliance
GE IS200TBCIH1B IS200TBCIH1BCE meets CE and RoHS industrial standards. The unit stores no significant electrical energy after power removal. Hence, technicians face no capacitor discharge hazards during regular maintenance or board replacement.
