Relay Outputs
The Receiver has 2 Relays and 2 Transistor (Open
Collector) Outputs to control up to 4 devices.
Higher Amperage (10 amp) applications that are
directly controlled, should use Relay Channels 1
and 2.

Lower Amperage (500 ma or lower) applications that
are indirectly controlled, should use Transistor Output
Channels 3 and 4.
Channel 3:
Terminal 5
Channel 4:
Terminal 4
NOTE: To verify, apply a resistance load of 200 ohms
between positive power (1) and terminal 6 or 4.
Measure voltage between negative power (3) and
terminal 6 or 4. When transmitter signal is received,
the transistor should clamp the voltage down.
Dipswitch Settings
NOTE: The Dipswitches on the
Receiver can be accessed by
removing the screw on the
bottom of the Receiver.
