REX-C100 PID Temperature Controller with Universal Input and SSR Output 48 × 48 mm

Digital Temperature Regulator with Solid State Relay Control Output

The REX-C100 is a digital PID temperature controller designed for accurate temperature measurement and regulation in heating and industrial systems. It features a universal measurement input that supports different types of temperature sensors, depending on the controller configuration.

This version features a solid-state relay control output (SSR). Instead of mechanical switching contacts, the controller provides a voltage pulse signal to an external SSR, which switches the power supplied to the heater or another compatible load.

SSR control is suitable for systems requiring frequent switching, precise PID temperature regulation and reduced mechanical wear compared with conventional electromechanical relays.

Main specifications:
• Model: REX-C100
• Type: Digital PID temperature controller
• Front panel dimensions: 48 × 48 mm
• Panel cutout: approximately 45 × 45 mm
• Universal temperature sensor input
• Solid-state relay control output (SSR)
• Control signal: 0–12V DC
• PID and ON/OFF control modes
• Digital display for process temperature and setpoint
• PID automatic tuning function (Auto-tuning)

The controller is suitable for electric heaters, furnaces, drying equipment, incubators, thermal chambers and industrial heating systems using an external SSR. PID control provides smoother heating regulation and helps maintain the selected temperature.

Important: This version has an SSR control output, not a power output for directly supplying a heater. An external solid-state relay compatible with the load voltage and power is required. The 0–12V DC control signal connects to the input of a compatible SSR. The temperature sensor type and measurement range must match the controller configuration.
