The DIN rail places the sensor 7 mm from the wall. This distance is very important for

the response time because the air inlets are situated at the back of the housing

facing the wall. The sensor should be mounted with the cable entry bushing upwards

and the draining holes downwards.

The sensor PCB is in an extra housing inside the outer housing.

If for some reason the PCB must be removed it must be handed carefully

and protected from electrostatic discharge! Normally, removing the PCB is

not required.

(permitting a ”3-wire” configuration). A single transformer may be used for the entire system. Note 2: aSENSE can deliver a voltage or a current loop for Out(1) / Out(2). To change between voltage and current output mode the hardware jumpers are used. There is one jumper for Out(1) and one for Out(2), so that one output can be a voltage output and the other a current output.
