ORP control cable output

Control cable provides a dry contact to control the device. Depending on the
setpoint configured it can generate a proportional PWM duty cycle or an ON/OFF
signal.

If the device controls a saltwater chlorinator, setpoint must be configured
as an ON/OFF signal.

Connect the cable to the external control input of the chlorinator or use it to activa-
te a relay or other device.

If you use the cable to switch a voltage, do not exceed the following values :

Maximum voltage

230 VAC

Maximum current

1 A
