NOTICE
PRM-230 (230 V AC)
The digital inputs are divided into two groups, each of four inputs. All inputs must be oper-
ated on the same phase. Different phases are not allowed.
Fig. 4.4 Connection of 3-wire sensors to PNP transistor inputs (PRM-230 only)
For PRM-24, it is allowed to connect sensors with switch contacts and transistor outputs within the
same input group. One voltage source can be used for two input groups.

necting the existing wiring (Fig. 4.6).
To replace the device:
− power off all connected lines including power sup-
ply
− remove all detachable parts of the terminal blocks
− replace PRM
− connect detachable parts with existing wiring to the
