The Autonics TK4S-14SN combines compact design with high-speed thermal response to deliver advanced performance in industrial control systems. With a sampling cycle of 50ms, it enables accurate and responsive temperature adjustments, critical in fast-moving production lines. The controller supports multiple control modes—ON/OFF, P, PI, PD, and PID—and accepts a broad range of inputs including thermocouples, RTD sensors like Pt100, and analog signals (0–10V, 4–20mA), ensuring integration across various machine types.
Powered by a 100–240VAC universal input, the TK4S-14SN ensures stability and global compatibility. Its single-channel SSR drive output (11VDC) supports ON/OFF, phase, and cycle control—perfect for heaters, blowers, and process equipment. The controller’s 4-digit 7-segment LED display allows real-time visibility of process variables, while adjustable parameters like proportional band (0.1–999.9%), integral time, derivative time, and hysteresis enable precise loop tuning. Display accuracy remains high at ±0.3% of full scale across typical operating ranges.
Engineered for rugged industrial conditions, the TK4S-14SN offers IP65-rated front panel protection, reinforced double insulation, and 2kV dielectric strength between input and power sections. It functions reliably in ambient temperatures from -10°C to 50°C, with humidity support up to 85% RH. Optional inputs like CT and digital (DI-1) extend its flexibility for alarm triggers or advanced cycle feedback. At just 150g, it fits neatly into panel-mounted systems without sacrificing features. Its robust specifications make it one of the most versatile High Performance PID Temp Controllers available in its class.
This controller is also popular in training institutions, helping engineering students learn practical PID concepts. It combines advanced features like manual reset, proportional tuning, and phase control with a user-friendly design. Whether you're upgrading legacy systems or designing new process equipment, the TK4S-14SN delivers long-term reliability, safety, and control.
