The C-RQ-0600S module is a basis for several versions of modules designed to connect temperature and humidity sensors, CO2 sensors, infrared motion sensors and universal analogue or binary signals.
The universal AI/DI inputs can be set to binary or analogue with a possibility to measure the temperature sensors: The resistance sensors PT1000, Ni1000, or the sensor with the thermistor NTC12k or KTY81-121 against the common GND wire. Other types of resistance sensors can use the resistance measurement range from 0 up to 160 kΩ, but the conversion into temperature and the linearization must be carried out by the user programme.
Binary signals are connected to the inputs only as potential free contacts against the common GND wire. The binary input can also operate in the mode of a balanced input.

Notes:
-
The inputs and outputs of the module are terminated in a miniature terminal block.
-
The terminal block allows the release of the wire using a narrow screwdriver (see the figure), or even a common pin: insert it into the hole above the space for the wire and then pull the wire.
-
The LED is next to the CIB terminal block and it is partly hidden under the housing of the module.

The modules are marked with number suffixes, according to their function: *.01 PIR sensor, *.02 RH+T sensor, ( *.03 sensor CO2). The module is supplied in the dummy plate housing in a wall-mounted switch, in optional designs.
