Industrial TOS-B4RJ3C Temperature Controller Relay

The TAS-B4RJ3C is Autonics' analog non-indicating temperature controller with a relay output and a J-type thermocouple input, designed for plug-in socket-base installation in a 48 × 48 mm front panel. It accepts J-type thermocouples for direct sensing and uses a SPDT relay to drive heating or cooling elements as part of a simple on/off control scheme. With a 0 to 300°C control range, this compact device is intended for quick replacement via its socket base in industrial equipment, reducing downtime when a control module needs to be swapped. Power is supplied from a line of 100–240 VAC or 110–220 VAC, 50/60 Hz variants, depending on configuration, making it suitable for global installations. As part of Autonics’ TA-series analog controllers, the TAS-B4RJ3C embodies a space-saving approach to reliable process control in demanding manufacturing environments.
