The manufacturer offers the signal converter as a wall mount version only. Each device has a
passive control input that can signal an external "out of specification error" (e.g. that there is no
flow). Additionally the control input can help to set the analog outputs (current outputs and limit
switches) to "zero" or to "manual hold" (e.g. for maintenance). For further details about the
control input please refer to
Control input (passive) on page 26.
The type and design of the cable glands depend on the version of the converter. The following
types and designs are available (the drawings show the device from the bottom side):
Cable glands (1 channel)
1 Power (M20)
2 Current output or relay output (M20)
3 Current outputs or temperature sensor (M20)

5 Possibility to connect a functional earth (only relevant for version with 24 V, which is in preparation)
