Price & Availability Contact us for pricing / 询价 It features a universal input that accepts thermocouples (K, J, E, T, R, S, B), RTDs (Pt100), and linear current/voltage signals, making it versatile for different sensor types. The controller provides ON/OFF or PID control with auto-tuning, ensuring stable and accurate temperature regulation. Its dual display shows both process value (PV) and set value (SV) simultaneously, facilitating easy monitoring and adjustment. Equipped with a relay output rated at 250VAC 3A, the HY-L804 can directly drive heating or cooling devices such as contactors and solenoid valves. It also includes an alarm output for over-temperature or deviation alarms, enhancing system safety. The front panel is IP65-rated, protecting against dust and water ingress, suitable for harsh industrial environments. The controller operates on 100-240VAC power supply, with an optional 24VAC/DC version available. Hanyoung Nux, a leading Korean manufacturer of industrial instruments, designs the HY-L804 for reliability and ease of use. The device supports various control actions (reverse or direct) and offers programmable parameters for proportional band, integral time, derivative time, and hysteresis. With its compact size and robust construction, the HY-L804 is ideal for plastic molding, packaging machinery, food processing, and HVAC systems. It is a cost-effective solution for upgrading or replacing existing temperature controllers in automation systems. The Hanyoung HY-L804 is a compact 1/16 DIN temperature controller designed for precise temperature control in various industrial processes. Basic Product Information Universal input: thermocouple, RTD, linear current/voltage PID control with auto-tuning and ON/OFF control mode Dual 4-digit LED display for PV and SV Relay output (SPDT) rated 250VAC 3A Alarm output for deviation or absolute value IP65 front panel protection Power supply: 100-240VAC (optional 24VAC/DC) 1/16 DIN size (48x48mm) for panel mounting Technical Specifications Version & Model Difference The HY-L804 is part of Hanyoung's HY-L series. Variations include different power supply options (100-240VAC or 24VAC/DC) and output types (relay, SSR drive, or current). The HY-L804 specifically has relay output; models like HY-L804S may have SSR drive output. Check the model suffix for output type. Application Scenarios Does the HY-L804 have auto-tuning capability? Yes, the HY-L804 features PID control with auto-tuning. When auto-tuning is activated, the controller automatically calculates optimal PID parameters based on the system response, ensuring stable control without manual tuning. What is the power supply requirement for the HY-L804? The standard model operates on 100-240VAC 50/60Hz. An optional version is available for 24VAC/DC. Always check the model code to confirm the power supply version. Can the HY-L804 be used for cooling control? Yes, the HY-L804 supports both reverse (heating) and direct (cooling) control actions. You can configure the control action in the parameter settings to suit your application. What is the input type supported by the Hanyoung HY-L804? The HY-L804 supports universal input including thermocouples (K, J, E, T, R, S, B), RTD (Pt100), and linear current (4-20mA) or voltage (0-5V, 1-5V) signals. You can select the input type via the front panel parameters.
