Industry Applications

• Process and loop control in chemical, energy, and water treatment plants
• HART-enabled device control in safe and certifiable environments
• Analog output in packaging, bottling, and machine control systems

Installation & Maintenance Notes

• Field-side power (SA) must be 18–32 V DC; wire shield to ground
• Ensure backplane in PID bank is energized before hot-swapping
• Remove module from base prior to field-side power removal to avoid arcing
• Bring shield bar to home earth ground when using shielded cables
