ALTERNATING RELAY
UL listed CSA recognized
• Duplex Alternating Control
• SPDT or DPDT Control Relay
• 10 Amp Rated
• Externally Controlled
The electronic alternating relay is designed to replace mechanical
style devices used in control applications requiring a duplexing
or alternating action of the control circuits to operate pumps,
compressors, etc. This is achieved by activating a control switch
which is common to one side of the input control voltage. The output
contact of the relay(s) change state when this switch is opened
(on de-energization of the control circuit). When the control initiate
switch is actuated and released or opened, the relay will change
state. The next time the initiate switch is actuated and released it
will change back to its original state. Two red LED’s located on the
top of the dust resistant enclosure provide the status of the relay.
