TX4S-24C Autonics Temperature Controller
Autonics TX4S-24C LCD PID Temperature Controller (48×48 mm, Current / SSR Output)
The Autonics TX4S-24C is a compact 48×48 mm LCD PID temperature controller with fast 50 ms sampling.
It offers selectable current (4–20 mA) or SSR drive output, powered by 24 VAC/DC, ideal for automation panels and thyristor/SSR control.
The Autonics TX4S-24C is a 48 × 48 mm DIN-size LCD PID temperature controller designed for precise industrial temperature control where 24 V AC/DC power supply is required. It features a clear LCD display, fast 50 ms sampling, and flexible output options.
This model supports selectable current output (4–20 mA / 0–20 mA) or SSR drive output, making it suitable for thyristor units, SSRs, and PLC-based control systems in OEM and automation panels.
