2-1 Features
This device is the controller for safety liquid leak sensor with the following features:
● This device and safety liquid leak sensor SQ4-A series are combined for operation.
● Maximum of 4 safety liquid leak sensors can be connected to this device.
● With the output polarity selection switch of the controller, the control output 1 / 2 (OSSD 1 / 2)
can be switched to the PNP / NPN output. SQ4-A□-P PNP output type and SQ4-A□-N NPN
output type cannot be used together.
● Replacement of the relay is not required with the semi-conductor output.
