Prop. press. regulator EB 80, fieldbus, port 1 unreg., no display - Riegler 153151

Proportional pressure regulator for valve island EB 80, fieldbus, port 1 unregulated (locally regulated output), without display The EB 80 proportional pressure regulator delivers precise, dynamic pressure control based on electrical input. Its closed-loop system uses a precision sensor and mini-solenoid valves to continuously adjust pressure in real time. The proportional pressure regulator fits any EB 80 island and supports up to 16 regulators per island, compatible with all EB 80 communication protocols. For multi-pole islands, it is available with external M12 electrical connection, accepting commands in Volts, mA and via RS232 protocol. The fieldbus versions feature integrated control, offering flexible connectivity and intuitive operation. Islands without valves can also be constructed, consisting exclusively of several regulators connected in series. Versions without display are configured remotely, while versions with screen and keypad allow direct configuration on the device and display of information and diagnostic values. Two pneumatic configurations are available: In variants with local regulation only, regulated air can be taken from a quick-fit coupling on the front while the island's air supply in port 1 passes through unregulated. On the other hand, versions with in series regulation set pressure at port 1 to supply all downstream modules (while the front outlet is present and operational as well, but closed off with a plug). For the fieldbus versions, please refer to the operating instructions for the electrical fieldbus connection module used.

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
