Material Composition
Front panel: IP65 polycarbonate membrane overlay, internal PCB FR-4 flame retardant substrate, metal alloy mounting bracket, silver alloy relay contact terminals
Structural Characteristics
Vertical 1/4 DIN panel insertion structure, rear screw terminal block for power, sensor and output wiring, detachable metal mounting clip for cabinet panel installation without fastener tools
Working Principle
Temperature sensor analog signal converted to digital temperature reading via internal signal conditioning circuit, compared against user-defined setpoint value. PID algorithm calculates corrective output signal to drive heating/cooling actuators, continuously adjusting output duty cycle to maintain fixed process temperature. Alarm logic triggers auxiliary relay when measured temperature deviates beyond user-programmed threshold.
Advantage Highlights
- Universal single unit supports all mainstream industrial temperature sensor types
- IP65 front panel permits installation on factory equipment exterior without protective cover
- Built-in program curve storage eliminates external PLC for batch thermal processing
- Auto-tune PID function cuts on-site commissioning configuration time drastically
Applicable Industries
Heat treatment furnace, plastic injection molding barrel temperature control, packaging heat sealer, laboratory drying oven, food baking tunnel, semiconductor reflow oven
Installation Requirements
- Install into standard 48×96mm 1/4 DIN instrument panel cutout
- Maintain minimum 50mm clearance behind controller rear terminal block for wiring heat dissipation
- Separate thermocouple/RTD sensor wiring from AC power cables by 10cm minimum distance
- Avoid mounting controller adjacent to high-power variable frequency drive units
Usage Precautions
- Do not expose front panel to continuous liquid immersion despite IP65 rating
- Avoid applying input signal exceeding maximum rated voltage/current for sensor terminals
- Perform PID auto-tune procedure after equipment thermal load modification
- Clean membrane keypad surface with dry microfiber cloth only, no solvent chemical cleaners
