Enables the construction of a circuit for remote on/off switching (max. distance 10 m) and for remote monitoring (fault/operating message implemented as a potential-free contact, max. distance 100 m). With this set, consisting of the remote query box and the appropriate cables and plug contacts, external on and off signals (e.g. timer operation or EMERGENCY STOP) can be received. In addition, you can query an operating and fault message in order to have it displayed centrally, e.g. on a control panel.
