Installation & Usage Notes
- Protocol Matching: Select network modules based on target protocol (PN/PB-DP/Modbus TCP/RTU)
- Terminal Selection: Choose PT plug-in terminals for frequent maintenance; fixed terminals for harsh/vibration environments
- RTD Wiring: For RTD models, verify sensor type (PT100/PT1000) and wiring configuration (2/3/4-wire)
- Power Supply: Ensure 24V DC (19.2~28.8V) input to avoid module damage; use decoupling capacitors for noisy power lines
- Mounting Spacing: Reserve ≥3mm between modules for heat dissipation, especially in dense layouts
- Calibration: For precision applications (temperature/potentiometer), verify accuracy post-installation (±0.1% FS tolerance)
- Environmental Protection: Install in dry, dust-free control cabinets (IP20 protection); avoid direct moisture or corrosive exposure
