FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the typical response time when an input signal turns on or off?

A: The typical response time for both the on-state and off-state transition is 1 millisecond.

Wiring & Installation:

Q: How is the 16-point input channel group wired to field power?

A: All 16 inputs share a single common power input terminal for simplified wiring.

Troubleshooting & Compatibility:

Q: What is the isolation voltage rating that protects the logic side from field faults?

A: The module provides 1500 volts of isolation between the field side and the logic side.

Replacement & Upgrades:

Q: What is the minimum current required for the module to register an input as being ON?

A: A minimum on-state current of 3.2 mA is required to register a logic 1 in the input status table.
