RailQUAD 8. Input module with 8 analog-digital inputs for DIN rail

Product code: ZIO-RQUAD8
QUAD is an analog/digital sensor that offers a large variety of functionality. It has 8 analog/digital inputs can be configured as binary inputs for sensors and potential-free push buttons, as temperature probe inputs or as motion sensor inputs. Eight room thermostats for heating/cooling control systems included. Can be used with third party NTC probes as long as the resistances are known at three temperatures points.
