Frequently Asked Questions (FAQ)

Q: What systems is the T8403 module compatible with?

• A: It is designed for use in the ICS Triplex T8100 and T8300 I/O chassis backplanes.

Q: Can this module handle analog current signals like 4-20mA?

• A: No. The T8403 is designed for monitoring DC voltage levels (e.g., 24VDC on/off signals), not analog current loops.

Q: What does "configurable thresholds" mean?

• A: You can set the voltage level at which the input is recognized as a logical ON (1) or OFF (0), allowing flexibility for different field device signal levels.
