The Autonics TK4M-24RN operates on a 100β240VAC~ 50/60Hz power supply and offers a 50ms sampling cycle to ensure rapid response to temperature changes. It supports ON/OFF, P, PI, PD, and PID control methods, making it suitable for both basic and advanced thermal systems. Input options include thermocouples (K, J, T, etc.), RTDs (Pt100Ξ©, Cu100Ξ©), and analog signals like 0β10V and 4β20mA, providing broad compatibility for industrial applications. Its relay output (250VAC~ 3A) enables direct load control, while the 4-digit 7-segment LED display ensures visibility and monitoring on the shop floor.
The controller includes key tuning parameters such as proportional band (0.1 to 999.9β/β), integral time, derivative time, and manual reset, enabling precise loop control. Its rugged build supports operation in ambient temperatures between -10Β°C and 50Β°C, and humidity levels up to 85% RH. The IP65-rated front panel protects against dust and moisture, and 2kV reinforced insulation between circuits ensures electrical safety in high-voltage environments. The controller weighs just 210g and is built for compact panel installations. With Β±0.3% F.S. display accuracy and optional features like dual alarm outputs and digital input (DI-1), the TK4M-24RN meets the demands of process-critical automation setups where both performance and protection are essential.
The Autonics TK4M-24RN balances high-end control features with robust industrial protection, making it ideal for both new installations and system upgrades. It helps teams maintain temperature accuracy, improve efficiency, and extend equipment life through better control.
