Applicable Industries: Marine, Offshore, Telecom, Data Centers, Hospitals, Mining, Construction
Structure & Design:
- Wall-mount or panel-mount enclosure
- Plug-in terminal blocks for field wiring
- Internal EEPROM for parameter storage (retains settings without power)
Installation Notes:
- Minimum 100mm clearance above unit for ventilation
- Use shielded cable for all analog signals
- Ground shield at one end only to prevent ground loops
