Detailed content
- Technical Specifications: Input type: universal analog input (thermocouple, RTD, DC voltage, DC current); display resolution 0.01% FS; control output: relay/voltage pulse/4‑20 mA analog output; communication interface: RS485 (Modbus‑RTU protocol).
- Functional Features: Dual‑line digital display; PID auto‑tuning control; upper/lower limit alarm output; peak/valley value hold function; parameter lock function; self‑diagnosis function.
- Performance Parameters: Measurement accuracy ±0.1% FS; sampling speed 250 ms; power supply 100‑240 V AC 50/60 Hz; insulation resistance ≥20 MΩ.
- Structural Characteristics: Panel‑mount design (96×48 mm cutout); dust‑proof front panel; key‑operated parameter setting structure; internal circuit with surge protection components.
- Working Principle: Collects analog sensor signals, converts to digital values via built‑in A/D converter, displays real‑time process values, executes PID control logic, outputs control signals to actuators, triggers alarms when process values exceed preset thresholds.
- Advantage Highlights: Universal input compatibility; high measurement precision; user‑friendly parameter configuration; strong anti‑interference performance; stable long‑term operation in harsh industrial environments.
- Applicable Industries: Chemical industry, food processing, pharmaceutical manufacturing, water treatment, HVAC systems, energy and power industries.
- Installation Requirements: Standard panel cutout mounting; ambient temperature -10 °C to 55 °C; avoid direct sunlight and corrosive gas environments; vertical installation recommended.
- Usage Precautions: Ground the controller shell reliably; separate power wiring and signal wiring; avoid overvoltage input to measurement terminals; regular calibration of measurement accuracy.
