Frequently Asked Questions

Can I mix current and voltage signals on the inputs?

Yes. The four input channels accept either 4-20mA or 0-10V signals depending on wiring.

What type of cable must I use for wiring?

You must use shielded twisted-pair cabling to protect analog signals from noise.

How does the removable terminal block benefit maintenance?

It allows module replacement without disconnecting individual field wires, saving valuable time.

What happens if the external 24V DC supply drops below 20.4V?

The module enters a fault state and stops processing analog signal conversions.
