The Autonics TK4L-B4CC supports a wide 100โ240VAC~ 50/60Hz power range, ensuring consistent operation even with voltage fluctuations. It delivers fast thermal feedback through a 50ms sampling cycle, helping process control systems respond in real time. The unit features a clear 4-digit 7-segment LED display and advanced PID logic that includes ON/OFF, P, PI, PD, and full PID control, giving engineers total flexibility in configuring control loops.
Input versatility is a key advantageโthis model accepts various thermocouples (K, J, T, R, etc.), RTDs (Pt100, Cu100), and analog signals (4โ20mA, 0โ10V), making it suitable for both legacy and modern systems. The control outputs include current (DC 0/4โ20mA) or SSR drive (11VDC), compatible with PLCs, solid-state relays, and actuator systems. Built-in RS485 communication enables remote monitoring or integration into SCADA and HMI platforms.
The TK4L-B4CC features IP65 front panel protection against dust and liquids, reinforced with 2kV insulation between input and power sections for operational safety. It performs reliably in temperatures ranging from -10ยฐC to 50ยฐC, with up to 85% relative humidity. Engineers can fine-tune behavior using adjustable proportional band (0.1โ999.9ยฐC), integral and derivative times (0โ9999 sec), and hysteresis for stable loop tuning. CT input, dual alarms, and digital inputs provide additional control logic flexibility, making it a preferred model for precision-critical applications.
Maintenance engineers value its display clarity, sensor range flexibility, and the ability to configure outputs for relay logic or SSR-based systems. For automation teams, its RS485 Modbus support simplifies integration into control panels and monitoring dashboards. With IP65 protection and high-precision analog handling, it stands up to dusty or humid plant conditions while maintaining consistent loop accuracy.
Whether youโre building a new control cabinet or upgrading an outdated PID system, the Autonics TK4L-B4CC is a reliable choice. Its build quality, feature set, and trusted brand backing make it one of the most dependable PID temperature controllers in India.
