CM-IWN.1S can be paired with the CM-IVN coupling unit to extend the measuring range from 1–200 kΩ up to 690 V AC and 1000 V DC. This makes it suitable for larger unearthed IT networks while preserving its 24–240 V AC/DC control supply and 2 x changeover outputs.
CM-IWN.1S is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails. It features screw terminals for secure connections and a recommended tightening torque of 0.6–0.8 N·m. This simplifies installation in standard automation panels and minimizes space impact.
Key specs include measuring range 1–200 kΩ, control supply 24–240 V AC/DC, two changeover contacts (2 x 1 c/o or 1 x 2 c/o), and rated currents of up to 4 A (AC-12) and 4 A (DC-12) at 24 V. It supports IP50 housing and UL/CSA, CE approvals for reliable industrial use.
Yes. For UL/CSA circuits, the device provides a 300 V AC maximum operating voltage on the Output Circuit, B300 contact rating, and flexible conductor accessories for UL/CSA wiring. It is designed to fit safety and performance expectations in North American electrical installations.
CM-IWN.1S carries IEC/EN 61557-8 and related IEC standards, CE, UKCA, UL/CSA, CB, CCC, and CQC certifications. It is designed for compliance in older and new installations, with documentation including DoC/Declaration of Conformity, RoHS compliance, and environmental resilience.
