The Autonics TK4H-B4RC is powered by a stable 100β240VAC~ 50/60Hz supply and operates with a swift 50ms sampling cycle, enabling fast response to temperature changes. It supports flexible control methodsβON/OFF, P, PI, PD, and PIDβallowing accurate and adaptive tuning across dynamic thermal environments. Engineers can easily monitor values using the 4-digit 7-segment LED display, which ensures visibility even in industrial panel conditions.
This controller is compatible with a wide range of sensors, including thermocouples (K, J, R, S), RTDs (Pt100, Cu100), and analog inputs (4β20mA, 0β10V), offering excellent integration flexibility. For output, the TK4H-B4RC provides both a robust relay output (250VAC~ 3A) and a selectable current or SSR drive output, supporting diverse system architectures. RS485 communication and digital inputs expand the functionality, enabling real-time monitoring and external signal interaction.
The unit features IP65-rated front protection, double insulation, and can handle up to 2kV dielectric strength between input and power terminals, ensuring user safety and system reliability. It performs stably across a temperature range of -10 to 50Β°C and humidity levels of 35β85% RH. With adjustable proportional band (0.1 to 999.9Β°C), integral/derivative time, and hysteresis control, the device provides full tuning capability for fine process control. Weighing approximately 211g, itβs compact enough for modern panel layouts without sacrificing durability or performance. Every technical aspect of the TK4H-B4RC reinforces its reputation as a trusted, industrial-grade PID controller from Autonics.
Whether you're an experienced engineer or an apprentice technician, the intuitive operation, robust insulation, and broad sensor compatibility of the TK4H-B4RC make it an excellent solution for building efficient, long-lasting temperature control systems.
