FAQs
The CM-ENS.23S mounts on standard DIN rails (TH35-15 or TH35-7.5) and uses screw terminals for secure wiring. It supports both 110–130 V AC and 220–240 V AC supplies with 50/60 Hz, and offers front-face potentiometers for sensitivity adjustments. With a tamper-resistant cover, ensure a clean, accessible panel layout to simplify commissioning and future servicing.
Key specs include a 0–1000 kΩ measuring range across 3 electrodes, and a 1 c/o SPDT output rated at up to 250 V / 4 A. It provides AC-12 durability up to 100,000 cycles and mechanical durability of 1,000,000 cycles. The device is IP50 protected, with screw-terminal connections and DIN-rail mounting for reliable, scalable installations.
Yes. It is designed to monitor conductive liquids and protect pumps from dry running and tanks from overflow, common in water treatment and chemical processing. With CE, UKCA, UL/CSA, CCC, RoHS compliance, and a robust IP50 housing, it supports regulated environments while enabling straightforward integration into existing control schemes.
The CM-ENS.23S carries CE and UKCA marks, UL/CSA listings, CCC declaration, and DNV GL certification, along with RoHS compliance and SCIP considerations. These certifications facilitate global approvals, reduce supplier risk, and streamline audits for regulated industries such as utilities, manufacturing, and chemical processing.
The relay’s long electrical durability (AC-12 100,000 cycles) and high mechanical durability (1,000,000 cycles) reduce replacement frequency and maintenance labor. Combined with tamper resistance, adjustable sensitivity, and easy installation, this minimizes downtime, improves process uptime, and lowers total cost of ownership in continuous operation environments.
