HWP T804-01-23-HL-P Temperature Controller

Overview

The HWP T804-01-23-HL-P is a high-precision panel PID temperature controller from HWP. The HWP T804-01-23-HL-P accepts universal sensor inputs including thermocouple, RTD, voltage and current signals, and provides PID regulation output for heating or cooling equipment. This unit supports relay output, SSR drive and 4–20mA analog transmission, with dual digital display for process value and set value. It is widely used in ovens, furnaces, packaging machines, extruders and test chambers for thermal control.

Features

The HWP T804-01-23-HL-P features universal input type, which can be selected by menu without hardware change. The HWP T804-01-23-HL-P supports auto-tuning PID function to optimize control parameters automatically. It comes with high and low limit alarm, sensor break alarm and power failure memory. The HL in the part code stands for high-low alarm; P represents analog transmission output. Standard 48×96 mm panel cutout.

Specs

Device Type: PID Temperature Controller Model: HWP T804-01-23-HL-P Brand: HWP Panel Size: 48×96 mm (vertical) Input: Universal input (K/S/B/E/J/T/R/N thermocouple, Pt100, Cu50, 0–10V, 4–20mA) Control Output: Relay / SSR / 4–20mA selectable Auxiliary: High & low alarm, sensor fault alarm Communication: Optional RS485 Modbus Power Supply: 85–265 V AC Display: Dual LED digital display Accuracy: ±0.2% FS Operating Temperature: 0°C ~ +50°C Mounting: Panel mount

Principle

The HWP T804-01-23-HL-P reads the temperature signal from the sensor, compares the measured value with the setpoint, and calculates output via PID algorithm. It adjusts heater or cooler power continuously to keep temperature stable. The alarm circuit triggers relay signal when temperature exceeds threshold or sensor is open.

Applications

The HWP T804-01-23-HL-P is used for temperature control of industrial oven, heat treatment furnace, plastic machinery, environmental test equipment and packaging lines. The HWP T804-01-23-HL-P is stocked as spare replacement for original control panels.
