REX-C400 PID Temperature Controller Thermostat (SSR Output) — K Thermocouple, 40A SSR Relay, Easy to Use

Compact PID temperature controller REX-C400 with SSR output and K thermocouple input. Equipped with a 40A SSR relay, this controller handles both heating and cooling applications with reliable PID regulation. Key features: - Dual-mode operation: two relays allow you to choose cooling or heating mode. Display can be set to °F or °C. - Clear status indicators: dedicated LED lights for cooling and power make system status easy to read even in low light. - Rugged, user-friendly design: bright, easy-to-read display housed in durable plastic and includes a convenient hanging tab for mounting. - Precise temperature control: adjust the target set value and the differential (hysteresis) value to manage temperature. Includes PID control logic for stable regulation. - Protection and calibration: built-in refrigerating control output delay protection plus temperature calibration for accurate results. Versatile uses: ideal for refrigeration, fermentation chambers, greenhouse fan control and other applications where maintaining a specific temperature range is critical.
