Industrial TK4S-B4CC PID Temperature Controller

Autonics TK4S-B4CC PID Temperature Controller is a compact 48×48 mm panel-mount device that provides precise, programmable temperature regulation for industrial heating and cooling processes. It accepts RTD and a wide range of thermocouples (B, C, E, G, J, K, L, N, PL-II, R, S, T, U) and supports On/Off, P, PI, PD, and PID control modes for flexible tuning. The TK4S-B4CC features two outputs that can be configured as 4–20 mA analog outputs or SSR drive, along with RS-485 Modbus RTU communications for integration with PLC or SCADA systems. Key specs include a 50 ms sampling cycle, a 4-digit 7-segment LED display with ±0.3% full-scale display accuracy, and a 100–240 VAC power supply, designed for standard panel installation.
