Electrical fieldbus connection EB 80, POWERLINK - Riegler 150962

Electrical fieldbus connection for valve island EB 80, POWERLINK The Electrical Connection - E subsystem powers EB 80 systems, transmits control signals to solenoid valves, manages I/O communication, and handles diagnostics. Available in multi-pole or fieldbus versions, the valve island operates identically with both (patented), supporting parallel and serial controls. Smart electronics across all modules enable advanced diagnostics. The system supports 12 VDC and 24 VDC operation (patented), tolerates overvoltages up to 31.2 VDC, and functions with a minimum pilot voltage of 10.8 VDC. Multi-pole versions retain full modularity and diagnostics and feature a single-piece metal housing. Fieldbus versions consist of a metal lower body, independent of protocol, and a technopolymer upper section tailored to specific bus protocols (except the IO-Link 64 OUT module, which comes with one-piece metal housing).

About Valve terminals

A valve terminal combines several directional valves, their electrical control and the shared air supply in one assembly. Instead of wiring and tubing every valve separately, one bus cable and one supply line run to the terminal. The valves handle flow rates of 200 to 800 Nl/min at operating pressures up to 10 bar.

What matters when choosing

• Define the function first. Options include 5/2-way monostable, 5/2-way bistable as an impulse valve, 5/3-way with closed centre, and combinations of 3/2-way NC and 3/2-way NO on one slice.
• The connection decides how much wiring is involved. Multipole suits manageable terminals with existing parallel wiring, the version with integrated Profibus DP connects to a fieldbus controller.
• Protection class follows the mounting location. IP 65 for direct mounting on the machine, IP 40 for a protected control cabinet.
• Flow rate from 200 to 800 Nl/min has to match the volume of the connected actuators and the required cycle time.
• Where pressure is controlled rather than only switched, the proportional modules cover a control range of 0.05 to 10 bar at a maximum inlet pressure of 10.5 bar.

Typical applications

• Central valve station for handling and assembly lines with many short cylinder strokes
• Decentralised control mounted on the machine module in IP 65 to shorten tubing runs and switching times
• Packaging and filling lines where grippers, slides and suction cups are coordinated over a fieldbus
• Applications with controlled pressure, for example contact forces set by the proportional modules between 0.05 and 10 bar
• Systems running vacuum and pressure on one terminal using versions with external pilot air

Housings are made from technopolymer, from painted aluminium or from a combination of both, sealed with NBR. The specified medium is filtered, unlubricated compressed air.
