PLC receiver Nero II 8422 DIN

PLC receiver Nero II 8422 DIN
The Nero II 8422 DIN PLC receiver is designed to switch on/off different electrical appliances (light, heaters, ventilators, electric motors, pumps etc.), as well as to set up controllable sockets.

The centralized control over Nero II 8422 DIN PLC receivers is carried out without additional wiring with Nero ll central and/or scenario remote controls by transmitting control commands through 230V~ power line. The device is an effective solution when it is necessary to operate an electrical load located at a relevantely big distance from the control point and it is difficult or impossible to lay additional electric wiring.


Installation and connection

• high level of differentiation: control over a wide range of electric appliances;
• DIN-bus installation to mount the device into a distribution switchboard;
• easy to connect and use;
• possibility to connect different electrical and automation appliances through a potential free contact (commutation of alternating voltage up to 250V or constant voltage up to 24V with current up to 16А).


There are 4 operating modes to select from when it is necessary to control electronic devices of another producer:
• inverse mode without memory;
• inverse mode with memory;
• direct mode without memory;
• direct more with memory.
