Autonics TAS-B4RK4F Analog Temperature Controller

Autonics TAS-B4RK4F is a 1/16‑DIN analog non‑indicating PID temperature controller that accepts a K‑type thermocouple input (CA) and provides a relay output rated for 250 VAC at 3 A. The setpoint range spans 32–752 °F with a 100 ms sampling cycle, suited for precise thermal regulation in small to mid‑sized applications, and it runs on 100–240 VAC at 50/60 Hz within a compact 48 × 48 mm DIN enclosure. A socket base (8‑pin PG‑08/PS‑08) is sold separately for easy mounting; the base is not included with the controller. Ambient operation is −10 to 50 °C (−20 to 60 °C storage) with 35–85% RH, and the unit incorporates double or reinforced isolation with 2 kV between the measurement and power sections. Full‑scale accuracy is specified as ±2% at 23 °C ± 5 °C, with a weight of approximately 107 g. This TAS series controller is ideal for reliable, compact temperature control using a simple analog PID approach with a relay output.
