Great for level control in hazardous environments! Intrinsically safe
inputs protect against possibility of explosion in areas of volatile liquids or
gases. Relay is designed to perform multiple functions, including lift
station monitoring and pump activation. Read instructions carefully if you
are unfamiliar with the hookup and operation of this type of
relay.
Intrinsically safe input relays are used in environments where
there is a danger of ignition or explosion. This product is UL listed in the US
and Canada and rated for Class I, Division 1, Groups A,B,C &
D.
