Relay Contact Rating
8 A @ 240 VAC resistive load or 30 VDC resistive load
5 A @ 240 VAC inductive load (cos f = 0.4)
3.5 A @ 30 VDC inductive load (L/R = 7ms)
See graph on other side for relay load ratings
Caution: Do not exceed socket voltage rating
Use an RC snubber for inductive loads
Output Test/Reset Button
