Contact type:
2 normally open contacts with
common connection
Maximum contact rating:
500 VA, max. 250 V, max. 2A at
48...62 Hz, resistive load
Minimum contact rating:

Note:
If the relays OUT1 and OUT2 operate external contactors, these
must be fitted with RC snubber circuits to manufacturer
specifications to prevent excessive voltage peaks at switch-off.
OUT3 AS UNIVERSAL OUTPUT
Galvanically isolated from the inputs. Parallel current/voltage
output with common ‘minus’ terminal (combined use only in
galvanically isolated circuits).
