Voltage monitoring relies on four measuring ranges (3-30 V, 6-60 V, 30-300 V, 60-600 V) to cover diverse supply conditions. This flexibility translates to fewer misdetections and more stable protection across different installations, from simple machines to multi‑voltage panels. The open‑circuit measuring principle ensures the output reacts only to true voltage deviations, reducing false trips and protecting sensitive loads. A 1 c/o SPDT contact rated at 250 V / 4 A provides a straightforward interface to PLCs or safety relays, simplifying wiring and panel space. The device features screw terminals and DIN rail mounting (TH35-15 or TH35-7.5), enabling quick retrofits and robust, maintenance-friendly connections. Housing IP50 with operation from -20 to +60 C supports harsh factory environments, while CE and UL/CSA certifications streamline global compliance. Durable AC‑12 operation (100000 cycles) and strong mechanical endurance translate to lower lifecycle costs and higher uptime.

Yes. The device is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails and uses screw terminals suitable for wires ferruled 0.5–2.5 mm², plus flexible/ferrule variants, enabling fast, reliable panel installs.
It monitors four ranges: 3-30 V, 6-60 V, 30-300 V, 60-600 V, and requires a control supply of 110-130 V AC. The RMS measuring principle supports accurate sensing for both AC and DC components in single‑phase circuits.
Yes. With 1 c/o SPDT contact rated at 250 V / 4 A, it interfaces directly with PLCs or contactors for signaling and interlocking, making it suitable for motor protection and drive control in conveyors and packaging lines.
The CM-ESS.1S carries CE and UL/CSA certifications, plus CCC and other declarations. This broad certification footprint supports compliance in European, North American, and other international markets.
With AC-12 durability rated at 100000 cycles and robust mechanical durability, the device minimizes replacement frequency. Easy diagnostics, documented manuals, and standard wiring reduce maintenance time and support faster ROI in new builds and retrofits.
