6.7.2 22R08A Output Relay Connections
WARNING
Verify that the main input power is OFF before attempting to make connections.
All relay outputs are capable of operating up to 8 A, 240 VAC, or 12 VDC circuits. Connecting to equipment or
contactors with higher voltage or current ratings requires an intermediate relay.
Total sustained current must not exceed 10 A for relays K5 through K8.
Note:
When connecting to inductive loads such as relay coils and motors, Cattron recommends that snubbers
be placed across the load in order to ensure reliability and long life of the output relay contacts.
shows the relay output connections for the 22R08A Receivers. Note that Relays K1 through K4 provide
form C (SPDT) outputs. Relays K5 through K8 provide form A (SPST) outputs and share a common bus.
COM refers to the input voltage placed across all relays.
6.7.3 22R08A Installation Testing
Before putting the system into service, perform the following testing procedure:
1. Apply the appropriate power to the receiver (12-24 VDC or 120 VAC).
2.
Verify that the POWER (DS3) LED turns ‘ON’. Refer to
3. Turn the transmitter
to ‘ON’.
4. Verify that the Signal (DS1) LED flashes.
5. Verify that pressing any function switch on the transmitter lights the corresponding relay on the receiver
and the Relay (DS2) LED.
Review all of the steps above to ensure the accuracy of the wiring.
