Autonics TAS-B4RJ4F is an analog, non-indicating PID temperature controller in a compact DIN 48 × 48 mm package with a socket base for easy panel mounting. It covers a temperature range of 32 to 752 °F (0 to 400 °C) and accepts RTD/PT100 sensors (lead resistance up to 5 Ω per wire) as well as K- and J-type thermocouples. The control outputs include a relay rated for up to 250 VAC, 3 A, and an SSR drive output of 12 V DC (±2 V) at up to 20 mA, enabling both direct switching and SSR-based control. Designed for analog temperature control in heating or cooling processes, TAS-B4RJ4F provides reliable, compact PID performance in panel-mounted installations with socket-base convenience.
