The CM-TCS.21P integrates PT100 temperature sensing to deliver precise measurements across a wide operating window (-50 to +50 °C), enabling timely protective actions and reduced wear on critical equipment. This feature translates directly into longer service life for motors and drives and less unplanned downtime in manufacturing lines. The device supports two configurable thresholds for over- and undertemperature, plus window monitoring, allowing engineers to tailor protection to specific machines and process conditions, which improves process reliability and safety. With 2 x SPDT outputs or a single 2-c/o configuration, integration into existing control logic becomes straightforward, reducing wiring complexity and enabling flexible logic sequencing in automation panels. The 24 V AC/DC rated supply and Easy Connect push-in terminals offer maintenance-free assembly and faster commissioning, lowering total installation costs. The compact DIN-rail design (TH35-15/ TH35-7.5) and screwless terminals simplify retrofits and new installations, while the sealable transparent cover (available as accessory) enhances security against tampering. Compliance to IEC/EN standards and robust IP50 housing assure durability in harsh environments, supporting long-term asset protection and easier regulatory alignment.

FAQs
Yes. CM-TCS.21P is designed for DIN rail mounting (TH35-15 or TH35-7.5) and uses screwless terminals for a fast, vibration-resistant connection. It supports flexible wiring (2x 0.5 to 1.5 mm²) and offers push-in Easy Connect terminals for maintenance efficiency and reduced installation time.
CM-TCS.21P uses PT100 temperature sensing with a measurement range of -50 to +50 °C. This enables accurate monitoring of process and equipment temperatures, providing reliable protection for motors, transformers, and other critical components in automation panels.
Yes. With two configurable outputs (2 x SPDT or 1 x 2 c/o), adjustable thresholds for over/undertemperature, and compatibility with 24 V AC/DC control systems, CM-TCS.21P is well-suited to motor protection schemes and can be integrated into existing control logic to prevent overheating and extend motor life.
The CM-TCS.21P carries CE and UL/CSA listings, UKCA marking, and a range of relevant standards including IEC/EN 60255-26, IEC/EN 60255-27, and IEC/EN 61000-6 series. These certifications support safe operation in industrial environments and help ensure regulatory compliance across multiple regions.
Maintenance is simplified by Easy Connect push-in terminals and a compact DIN-rail footprint, reducing labor and downtime during installation. The device’s durable IP50 housing and long electrical/mechanical durability (AC-12 and high-cycle operation) translate into lower replacement costs and improved asset uptime, delivering a favorable return on investment in steady-state industrial environments.
