1. System description
The contactor monitors industrial processes for safe operation.
The unit analyses current (0/4 ... 20 mA) and voltage signals
(0/2 ... 10 V) and switches two independent output relays if the
values either exceed or undercut the preset alarm set points.
Applications include pump control in the waste water industry,
level measurement in silos can be economically achieved.
Transmitters connected can be supplied using the optional built-
in loop power supply.
