4DO or 8DO Expansion module
Connection of DOs
One 12V / 24V AC/DC ’very low voltage’ voltage-relay type digital outputs: the DOs are compatible with 24 V relays and electrical
cabinet indicator lights.
By default, and following a total power cut (24 V and Battery), DOs are in their 'open' state (idle state = 0).
However, the state of each DO is retained during product reinitialisation.
The user defines the ‘bistable’ or ‘impulse’ control type when configuring each DO data point.
The DO do not allow direct control of power units.
Example of control of 2 DC relays by 2 DO:
