2 x SPDT outputs, configurable as 2 x 1 c/o or 1 x 2 c/o contacts, provide flexible alarm, interlock, and signaling options. This translates to faster fault isolation and reduced downtime in packaging lines, CNC machines, and other automated equipment. The unit runs from 24 V AC/DC and accepts a PT100 sensor across a -50 to 50 °C range, enabling consistent protection across varied industrial environments and simplifying inventory with a single device for multiple lines. A sealable transparent cover option helps secure critical configurations, supporting governance in regulated sectors like food processing and pharmaceuticals while maintaining easy access for authorized maintenance. Screw-terminals with double-chamber cage connections offer robust, vibration-resistant wiring, with a tightening torque of 0.6–0.8 N·m for reliable field connections. DIN rail mounting (TH35-15/TH35-7.5) and a compact 22.5 mm width support dense panel layouts. High IP40/50 protection, extended electrical durability (AC-12 100,000 cycles) and mechanical durability (30,000,000 cycles) contribute to low maintenance and longer device life, helping minimize total cost of ownership. Compliance with IEC/EN 60255-26, IEC/EN 61000-6-2/3 and CAN/CSA 60947-5-1 reduces certification time for global deployments, while UL/CSA, CE, and UKCA certifications streamline cross-border acceptance.

FAQs
Install on a standard TH35 DIN rail (TH35-15 or TH35-7.5). The module is 22.5 mm wide and uses screw-terminal connections. Tighten terminals to 0.6–0.8 N·m and strip wires to 8 mm. Mounting clips securely snap onto the rail to ensure vibration resistance in industrial environments.
CM-TCS.21S supports two configurable SPDT outputs: either two separate 1 c/o contacts or one 2 c/o contact arrangement. This enables flexible signaling for alarms, interlocks, or control signals, minimizing additional relays and wiring while preserving wiring clarity in control cabinets.
The relay uses a PT100 input to monitor temperatures from -50 to +50 °C. It performs overtemperature and undertemperature monitoring with adjustable thresholds, facilitating window monitoring and precise protection aligned with process requirements.
CM-TCS.21S carries CE, UKCA, and UL/CSA certifications, along with RoHS/REACH declarations. It also aligns with IEC/EN 60255-26 and CAN/CSA 60947-5-1 standards. These certifications simplify global deployment, ensure compatibility with safety and electromagnetic standards, and support regulatory compliance across key markets.
A tamper-resistant sealable cover reduces unauthorized adjustments, while IP50 housing and robust contact ratings provide durable field service life. Electrical durability (AC-12 up to 100,000 cycles) and mechanical durability (up to 30,000,000 cycles) minimize maintenance downtime, lower replacement costs, and improve long-term return on investment in high-availability systems.
