Autonics TAS-B4RP4C Digital Timer Relay Module

Autonics TAS-B4RP4C is an analog, non-indicating PID temperature controller housed in a compact DIN 48 × 48 mm package that accepts Pt100 RTD input and drives a relay output rated for 250 VAC at up to 3 A. It is powered from 100–240 VAC at 50/60 Hz and uses a dial-setpoint (non-display) for configuration, making it suitable for panel mounting in industrial environments. The controller covers a 0–400 °C temperature range, samples at 100 ms intervals, and offers setting accuracy of FS ±2% at 23 °C ±5 °C. It supports both ON/OFF and PID control modes, with insulation described as double or reinforced, and it operates in ambient conditions from -10 to 50 °C with 35–85% RH. Weighing roughly 107 g, this device is designed for applications such as heating or cooling regulation in ovens, dryers, and other process equipment where a rugged, straightforward analog control solution is preferred.
