Autonics TX4S-A4C Digital Temperature Controller

Autonics TX4S-A4C is a digital temperature controller with a four‑digit LCD display (11‑segment) that supports ON/OFF, P, PI, PD, and PID control for precise process temperature management. It is powered from 100–240 VAC at 50/60 Hz and consumes up to 8 VA, making it compatible with standard industrial mains. The unit accepts a wide range of sensors, including thermocouples K, J, T, R, S, and L, and RTD options Pt100Ω and Cu50Ω, with a 50 ms sampling cycle for responsive control. Output options include a DC current output of 0–20 mA or an SSR drive output at 13 V DC, plus an ON/OFF mode for simple switching. The TX4S‑A4C features a front IP50 rating, double insulation with 3 kV dielectric strength between primary and secondary circuits, and an operating environment of −10 to 50 °C (−20 to 60 °C in restricted use) with 35–85% RH. Weight is approximately 146 g, offering a compact panel‑mountable solution for temperature regulation in a variety of industrial applications.
