The choice of index can trigger outputs with either one of the modes 0-10V or PWM for each outputs. Power is supplied via the 12V output of a controller UVR16x2 or RSM610. This puts the module at very low DL bus load. In connection with auxiliary relay modules (e.g. HIREL22), the module AO4-DL can also be used to supply additional switching outputs.

The AO4-DL is also the next device in our universal casing for small devices, which is suitable for top-hat rail mounting.
