Q: What is an Application Interface and why should I use it?

A: An Application Interface is essentially an I/O module used to connect hardwired sensors to a Wireless I/O Portal or CloudGate. During setup, you'll determine whether your application requires hardwired sensing. If it does, you'll select the appropriate interface module.

We offer dedicated modules for specific input types, such as the AB1 module for six 2-wire 4–20mA sensors, or combination modules like the AA1, which supports four 0–10V sensor inputs and two resistance-based inputs like thermistors.

If no hardwired inputs are needed, an "XX" code can be used in the Application Interface section of the part number to indicate that.
