Pre-assembled relay and DIN mount socket.

Universal screw terminals (flat and Phillips). Relays are used as interface modules. They perform different tasks depending on the version and are used to switch circuits on, off, and over.

Switching devices that are susceptible to faults compromise the availability of machines and systems. Thanks to the wide range of products from. Phoenix Contact, cost- effective . BAswitches the command to the interposing relay.

The process voltage for the interposing relay is switched by the command output supervision module. Two output relays are required for each command in case of 2. The relays on these interposing terminals are intended to be controlled with standard 24VDC 0. Symbols and designations, based on the IEC 617-series,. Block symbols and qualifying symbols.

The asterisk must be replaced by one or more letters or qualifying symbols indicating the parameters of the device. Protection relay with enabling input. The interposing relay is used as an interface between the drive control unit and switchgear located in the motor control centre.

It possesses two relays which are driven via the inputs E Eand E5. The connected switchgear is operated by the relay contacts via the outputs K2 Kor K3 K3 K33. When the signal (S) is closed the time delay (t) begins, after the time delay is complete the relay contacts.

Opening the signal starts the time delay, after the time delay is complete the contacts return to their shelf state. If the signal is closed or opened before the time delay is . The reliability of industrial automation equipment is becoming more and more important with the increasing use of electronic modules.
