Ruland Bellows, 25mm Outside Diameter, 8 mm, 9 mm Bore, 38.7mm Length Bellows Coupling

The DELTAplus Meter is an electronic electricity meter for DIN rail mounting in distribution boards or small enclosures. The meter is designed according to ABB’s ProM standard.

The DELTAplus Meter is easy to read with its LCD (Liquid Crystal Display) with 7 mm high digits and several symbols.
The meter has a polarity independent, solid state (semiconductor) relay that generates pulses proportionally to the measured energy.
A red LED (Light Emitting Diode) flashes proportionally to the energy measured. The DELTAplus Meter can be equipped with inputs or outputs for control and alarm handling as well as pulse counting. The meter is equipped with unique instrumentation functions enabling it to read the essential electrical units.

DELTAplus Meters with integrated EIB, M-bus or LON-bus communication, are easy to read remotely in a cost-effective way without conversions via traditional pulsed output. The DELTAplus meter is also equiped with an IR output that can be connected to the ABB Serial Communication Adapter.

Selection of the information in the LCD-display and programming of the DELTAplus Meter is performed via two programming buttons. These buttons can be sealed.

The Ruland D-Bore bellows coupling has fewer convolutions than comparably sized high misalignment styles allowing for increased torsional stiffness making it the ideal choice for precision positioning applications. The D-Bore allows for positive drive in applications where the coupling can not slip. It is comprised of two anodized aluminium hubs and a stainless steel bellows for lightweight and low inertia. It is also engineered with a balanced design for reduced vibration at high speeds up to 10,000 RPM.

RoHS3 and REACH compliant
Hardware is metric and tests beyond DIN 912 12.9 standards
Thin walls of the bellows are able to flex while remaining rigid under torsional load
