Frequently Asked Questions

Q: What is the IS200TDBTH2ACD?
A: It is a terminal board developed by GE under the Mark VIe series.

Q: What is the operating temperature of the IS200TDBTH2ACD?
A: -30 to 65°C.

Q: What are the dimensions of the IS200TDBTH2ACD?
A: 17.8 cm wide and 33.02 cm high.

Q: Are the current draws of the 24 input channels of the IS200TDBTH2ACD completely consistent?
A: Not fully. Channels 1–21 are limited to 2.5 mA, while 22–24 support 10 mA.

Q: What is the voltage fluctuation tolerance of the IS200TDBTH2ACD for different wet contact voltages?
A: It supports 32–64 Vdc in 48V mode and 100–145 Vdc in 125V mode.

Features
The board supports 24 isolated contact inputs with 24/48/125 VDC wetting voltage. Inputs include noise and surge suppression for stable operation.

It provides 12 Form-C relay outputs and supports an optional relay expansion card for added flexibility.

In Mark VIe systems, it integrates with PDIO I/O packs via Ethernet through three D-type connectors on the TDBT board.

PDIO connections: JR1 links to the R controller, JS1 to the S controller, and JT1 to both. In TMR systems, each PDIO connects independently to its controller.
