Mount the CM-PVS.81P on a TH35 DIN rail (TH35-15 or TH35-7.5) in the control panel. Use the screwless push-in terminals for easy connections and wire 2x 0.5–1.5 mm² conductors with an 8 mm stripping length. Connect the two SPDT outputs to the control circuit or PLC inputs, and supply the device with 200–400 V AC as specified. Ensure proper clearance and verify insulation ratings before operation.
The CM-PVS.81P provides phase failure detection, phase sequence monitoring, and over-/undervoltage monitoring with adjustable thresholds and a selectable tripping delay of 0–30 seconds (and a 200 ms start-up delay). These features prevent motor misoperation, reduce downtime from power quality issues, and protect connected equipment from voltage anomalies.
Yes. The device operates from -25 °C to +60 °C and supports mounting on standard DIN rails. It features an IP50-rated housing with IP20 terminals, making it well-suited for factory environments. The unit is designed to meet multiple international standards, aiding integration in global automation projects.
The CM-PVS.81P carries CE conformity, UL 508 / cULus recognition, and CAN/CSA C22.2 No.14 certification, among others. These certifications confirm compliance with essential safety and performance requirements across Europe and North America, simplifying procurement for regulated industries and ensuring consistent protection in panel installations.
The relay features maintenance-free Easy Connect technology and is built for long life, with electrical durability rated for up to 100,000 AC-12 cycles and 30,000,000 mechanical operations. This translates to lower maintenance costs and fewer field interventions, particularly in high-cycle automation environments.
