Single Relay Output 1-3 Performance
Positions
Optional in Plug-in Modules 1, 2 & 3.
Contact Type:
Single pole double throw (SPDT).
Contact Rating:
2A resistive at 120/240V AC
Lifetime:
>500,000 operations at full rated AC voltage/current. De-rate if
switching DC loads.
Isolation:
Reinforced safety isolation from inputs and other outputs.
CAUTION:
Plastic pegs prevent fitting of older non-reinforced single relay
modules
– Remove the peg to fit dual relays (all dual relay modules have
reinforced isolation).
