Its high level of reliability and cost optimized design make the DN 240M the first choice in customer applications.
Unique in its price class, the DN 240M provides application flexibility thanks to the calibrated range.
The desired input and output range can be easily set by terminal pins and due to the calibrated range selection no further adjustment is necessary.
The flat module with 15.5 mm height for pcb assembling saves space in the customer application.
