Description

It has 8 inputs to which it is possible to connect normally open buttons or switches to send DALI commands to the system. Inputs 1 - 4 can be configured as 0 - 10 VDC analog inputs allowing, for example, to connect light sensors. Through these inputs it is possible to recall scenes or interact with the Scheduler function of the Imagine system (conditions).

Main features

Status LED providing information on the operating mode

current: normal operation, initialization, selection or closing

contact.

Select button.

Can be used with normally open buttons or switches.

Can be used with analogue inputs from 0 - 10 VDC.

Programmable via IMAGINE Workshop software.

Can be used with timers.

Installation notes

The SC terminal of this module must be connected to ground to ensure correct operation.

The maximum length of the wires connecting the input unit inputs to the buttons (or switches) is 50 meters.

The analog inputs must be powered by an external source (0 - 10 VDC).

If the device is used in environments subject to a lot of electrical interference, the DALI cable must be shielded and grounded.
