Frequently Asked Questions

What differentiates the IS200DTCIH1ABB from the TBCI board?

The IS200DTCIH1ABB is exclusively for simplex applications and features a more compact physical footprint. It is specifically optimized for 24 VDC scaling.

Do all 24 circuits maintain the same current rating?

No. The first 21 circuits operate at 2.5 mA, while circuits 22 through 24 operate at 10 mA.

What is the recommended processor board for this unit?

We highly recommend pairing this unit with the VCRC processor board for optimal signal integrity.

Selection Guide

For new installations, verify that your rack space supports DIN-rail mounting. If your project requires more than 24 inputs, ensure you order two IS200DTCIH1ABB modules to utilize the VCRC dual-board expansion capability. Always confirm your control system is running the GEH-6421C firmware version for full compatibility.
