Designed for precise and stable thermal automation, the Autonics TK4S-14RN integrates a 50ms sampling cycle to ensure ultra-fast sensor response across thermocouple, RTD, and analog inputs. It supports versatile control methods including ON/OFF, P, PI, PD, and PID modes, giving engineers full flexibility for tuning temperature behavior to suit both rapid and slow heat processes. The relay output system (rated 250VAC~ 3A) offers robust switching in heating and cooling control loops.
A standout feature is its wide input compatibility — from thermocouples like K, J, R, and S to analog inputs such as 4–20 mA, 0–10V — all with ±0.3% full-scale display accuracy. The power supply range of 100–240VAC allows direct deployment across global panel standards. With IP65 front panel protection, this controller can operate reliably in dusty or semi-moist environments like food packaging lines, plastics manufacturing, and industrial ovens. Its compact construction and intuitive 4-digit 7-segment LED display make real-time diagnostics easy, even for junior technicians.
Additional trust factors include 2kV dielectric insulation for safety, support for optional digital inputs (DI-1) and CT input, and adjustable parameters like hysteresis and manual reset. With just 150g of weight, the TK4S-14RN fits perfectly into space-constrained cabinets. For professionals seeking performance without complexity, this controller delivers.
Whether you're building new systems or upgrading old ones, the TK4S-14RN gives you accuracy, reliability, and ease of use — all in one compact, rugged unit. To explore more temperature controller models or check compatibility, visit the Autonics Temperature Controller page on IndMALL.
