SAIA PCD7.W202｜Industrial Grade Human-machine Interface｜
Industrial Operator Panel / HMI
Display & Operation
Display Type: Monochrome LCD, typically 3.5″ or 4″ (QVGA 320 × 240 resolution).
Brightness & Readability: Optimized for strong or weak ambient light in workshops; clear display of data and status.
Language Support: Chinese, English and other characters configurable via dedicated software.
Operation Mode:
Primarily physical buttons (industrial-grade silicone or metal).
Wear- and oil-resistant; >1 million press life for long-term frequent use.
Customizable button functions (Start/Stop, Parameters +/−, Confirm/Cancel, etc.) to match control logic.
Some models offer simple touch operation as an option.
2. Communication Compatibility — “Master-Slave Collaboration”
Core Communication: High-speed serial link to SAIA PCD series PLCs (PCD2/3/6) using SAIA optimized protocol; low latency (<100 ms) for real-time synchronization.
Extended Compatibility:
Select models support standard industrial serial protocols (e.g., Modbus RTU over RS-485/RS-232).
Adaptable to third-party small/medium PLCs (Siemens S7-200, Schneider Modicon M200) or sensors/actuators.
Check individual model datasheets for exact protocol support.
Industrial-Grade Reliability
Protection Level:
Front: IP65 (dust and splash-water protection for workshop cleaning/oil splash).
Rear: IP20 (to be installed in a control cabinet/protective box).
Environmental Adaptability:
Standard operating temperature −10 °C to +50 °C.
Wide-temperature models −20 °C to +60 °C for cold storage or metallurgical environments.
Meets EN 61000-6-2 industrial EMI standards to resist interference from motors, drives, etc.
Power Supply: 24 V DC industrial standard (input 18–30 V DC).
Power Consumption: Typical <5 W for low heat and energy efficiency; suitable for continuous operation.
SAIA PCD7.W202｜Industrial Grade Human-machine Interface｜
Configuration & Maintenance — Lightweight & Easy
Configuration Tool: Supplied with SAIA official configuration software (e.g., SAIA PCD Studio).
Graphical, drag-and-drop interface (indicator lights, numeric boxes, button controls).
Customizable alarms, parameter ranges to prevent misoperation.
Maintenance Convenience:
Supports online firmware upgrade via communication port (no disassembly required).Local backup of parameter/configuration files for rapid restoration when replacing devices, reducing downtime.
Typical Applications
Industrial automation systems requiring compact, robust operator panels.
Machine-level control and monitoring with SAIA PCD PLCs or third-party PLCs.
Harsh workshop environments needing IP65 front protection and wide-temperature operation.
By structuring the information in this manner, the article provides a clear and organized understanding of input channels, transducer supply, and communication implementations in distributed control systems.
