Frequently Asked Questions

Q: How do I know if I need the IS200VTCCH1C or the VTCCH2?
A: The IS200VTCCH1C supports E, J, K, S, and T types. For B, N, or R types, you must use the VTCCH2 board.

Q: Is manual calibration required upon installation?
A: No, the board performs continuous automatic self-calibration during operation.

Q: What does the "FAIL" LED indicate?
A: It typically signifies a loss of communication with the VME backplane or an internal hardware diagnostic error.

Q: What is the benefit of the conformal coating?
A: The coating provides essential protection against humidity, dust, and corrosive elements in industrial environments.
