The TK4W-R2RR delivers accurate temperature control using a fast sampling cycle of 50ms for quick system feedback. Designed to operate on a wide power input range of 24VAC~ 50/60Hz and 24–48VDC, it adapts well to low-voltage and control panel environments. This temperature controller supports ON/OFF, P, PI, PD, and PID control methods, giving users the flexibility to configure control loops based on application sensitivity. Input compatibility includes thermocouples, RTDs, and analog signals with exceptional accuracy (±0.3% F.S. ±1-digit at room temperature). The dual relay outputs (250VAC~ 3A) make it suitable for driving resistive loads or intermediate control circuits. A 4-digit 7-segment LED display ensures visibility even in low-light factory conditions. Built-in IP65-rated front protection and double insulation enhance both environmental and electrical safety.
Advanced tuning capabilities such as proportional band (0.1 to 999.9°C), integral time, and derivative time offer precise control adjustments. The unit features manual reset and adjustable hysteresis for sensitive process switching. Additional functionalities include CT input, digital input (DI1/DI2), and transmission output (DC4–20mA), enabling integration with PLCs, SCADA systems, or signal monitors. Operating conditions are optimized for -10°C to 50°C ambient temperature and 35–85% RH humidity, with a compact form factor of approx. 211g. Its internal design includes reinforced insulation to meet industrial-grade dielectric strength standards (2kV between input and power parts).
The Autonics TK4W-R2RR is widely used in furnaces, heat treatment equipment, plastic molding machines, thermal test chambers, and process lines where consistent temperature stability is critical. Maintenance professionals trust this model for its proven reliability in daily operation, while engineers appreciate its ease of setup and tuning flexibility. Even junior technicians or engineering students can handle it with confidence due to its intuitive display and structured menu.
