AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a phase loss, phase reversal, phase unbalance, undervoltage, or overvoltage condition. These relays are designed to provide protection for most generator systems and applications that use non-sinusoidal waveforms. With non-sinusoidal waveforms, the true RMS voltage measurement ensures accurate sensing, eliminating nuisance tripping.
Also added are voltage monitor relays for AC single-phase (50 to 60 Hz) or DC circuits to protect equipment from voltage faults. Over/under voltage relays, with fixed or adjustable time-delay drop-out, offer protection from over-or under-voltage conditions. Voltage band relays protect equipment required to operate within an upper and lower voltage limit. The relay is energized if the monitored voltage remains within the adjustable range.
The new ProSense PMRU-2C Phase Monitoring Relays start at $79.00, and the ProSense Voltage Monitoring Relays start at $65.00. All new relays have a one-year warranty.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
