The SU 502 is a single channel controller for level detection of KROHNE limit switches with 8/16 mA output. The controller powers connected sensors and simultaneously processes their measuring signals. Via the integrated relay, simple control tasks can be solved. Typical applications are monitoring functions such as overfill or dry run protection. The SU 502 can also be used in hazardous areas and Safety Instrumented Systems (SIS). Optionally, an additional second relay can be ordered. Via a DIL switch the function of the second relay can be determined. It can be configured as fail safe relay or as second level relay.
