The Autonics TK4S-24CR is a versatile High Performance PID Temp Controller offering a 50ms sampling cycle and multiple control algorithms including ON/OFF, P, PI, PD, and PID, giving engineers full control over dynamic temperature processes. It supports an extensive range of sensor inputs—such as thermocouples (K, J, R, T, etc.), RTDs like Pt100 and Cu50, and analog inputs (4–20mA, 0–10V)—making it compatible with diverse applications and legacy systems.
This model operates on a broad 100–240VAC power supply, removing the need for external converters. The display is a bright 4-digit 7-segment LED that ensures clear visibility in factory settings. Engineers can fine-tune parameters like proportional band (0.1–999.9%), integral and derivative time (up to 9999 sec), and hysteresis. Output options include a relay output (250VAC~ 3A) and SSR drive (11VDC), enabling smooth integration with both electromechanical and solid-state devices. The IP65-rated front panel ensures dust and water resistance, while double insulation and a dielectric strength of 2kV enhance safety in high-voltage environments.
Optional CT input and digital (DI-1) input functions extend the controller’s capabilities for advanced monitoring and alarm setups. Input accuracy is consistently maintained at ±0.3% F.S. for thermocouple, RTD, and analog signals under standard room temperature conditions. Its compact build of approximately 150g makes it ideal for dense control panels. The TK4S-24CR stands out in its class for reliability, configurability, and seamless sensor integration.
In education and training, engineering institutes rely on this model to teach real-world control logic and loop tuning principles. For R&D labs and OEM panel builders, the compact form factor, strong insulation, and universal compatibility make it a trusted choice.
