Figure 4-13. KHL8924 Relay Output Wiring
NOTES:
•
The indicator power must be clean and isolated from the control power used to run relays, solenoids, and
motors. Also the indicator ground must be separate from the control power ground.
•
Solid state relays typically leak some current during their off state (4ma to 10ma). When used with certain
relays or neon indicator lights, a resistor wired in parallel to the load may be required to shunt this current
and allow the device to turn off.
•
When using these outputs to drive other relays, suppressors are required on the external relay’s coil.
•
Insure that the load cell wiring is routed separately from all control wiring.
