FAQ

This module uses AS-i Profile S-7.A.C, which is standard for a device with 4 digital inputs and 3 digital outputs.

Each of the three digital outputs is rated for a maximum load of 0.5 Amperes (500mA).

The module requires two separate power sources: one from the AS-i bus (via the yellow flat cable) for the bus communication and inputs, and a separate external 24V DC auxiliary power supply (AUX) for the outputs.
