|
|
Common per channel
|
1 for every 2 channels (channels 0 to 7)
1 per channel (channels 8 to 11)
|
|
Type of contact
|
normally open (channels 0 to 7)
normally open/normally closed (channels 8 to 11)
|
|
Key:
|
|
|
(1)
|
Limited to 7 A per terminal (NC) in the case of 2 outputs with common terminal.
|
|
(2)
|
Maximum value of current which can cross the contact without damaging it.
This value, which is associated with the relay, should not be confused with the permissible current, relating to the module. The permissible current takes into account the breaking capacity of the relay (maximum switching current) and the characteristics of the other components which constitute the output.
|
|
(3)
|
With an inductive load on an AC supply, an RC or GMOV peak limiter circuit must be wired across the load.
For DC, wire a reverse mounted diode in parallel to the load.
