Valve module for compressed air-operated sensor cleaning

Design according to the minimum requirements for measuring instruments used at waste water treatment plants defined by ATV (waste water association) in bulletin M256

Valve module for compressed air-operated sensor cleaning:
- The valve module is time-controlled direct from:
* IQ SENSOR NET Bus or
* A relay of the Transmitte series 170/296 or IQ SENSOR NET or
* Directly by the MIQ/VIS connection module for UV/VIS sensors

The cleaning is done by means of external compressed air
- The compressed air stream is effective via a separate cleaning head that is screwed on the sensor or directly at the UV/VIS sensors

The valve module has the following features:
- With 2 free SENSOR NET connections, usable for IQ sensors or for the SENSOR NET
- Stack mounting (and at the same time electrical connection) to any IQ SENSOR NET module possible
- High EMC interference immunity
- Integrated lightning protection
