The Autonics TC4S-12R is engineered for precision thermal control in compact automation setups, operating on both 24VAC 50/60Hz and 24–48VDC power supplies for flexible integration. It offers a rapid 100ms sampling cycle and supports multiple control modes including ON/OFF, P, PI, PD, and PID, ensuring smooth adaptation to varying load dynamics. With selectable outputs—Relay (250VAC 3A) or SSR drive (12VDC)—the controller suits diverse heating and cooling scenarios. The clear 4-digit 7-segment LED display enables real-time visibility of temperature readings and settings. Inputs are compatible with standard K, J, L thermocouples and Pt100Ω/Cu50Ω RTDs, making it an easy drop-in replacement for legacy systems. Its control flexibility is enhanced by an adjustable proportional band (0.1–999.9°C), integral and derivative time (0–9999 sec), and customizable hysteresis, ensuring fine-tuned response across applications.
Compactly housed in a DIN W48×H48mm case and weighing just 141g, the TC4S-12R fits seamlessly into crowded panels. The unit features double/reinforced insulation with up to 2kV dielectric protection between power and measurement circuits, and operates reliably from -10°C to 50°C at 35–85% RH. An alarm output comes standard to alert for temperature anomalies. These robust features make it a trusted component for industries like pharmaceuticals, food & beverage, plastics, packaging, and textiles, where stable thermal regulation is critical to process consistency and product quality. It’s ideal for drying ovens, sealing machines, laboratory incubators, heat tunnels, and other compact control applications.
Whether you're a junior maintenance engineer looking for a user-friendly controller, or an experienced automation professional upgrading a legacy system, the Autonics TC4S-12R delivers reliability, configurability, and compact design. Its ease of use combined with advanced functionality makes it suitable for both training labs and full-scale industrial setups.
