Electrical and Control Data

• Supply voltage ranges from 24 to 36 VDC ±10%
• Current consumption reaches 700 mA at 24 V and 500 mA at 36 V
• Outputs use NPN open collector for ion level warning, condition warning, and alarm
• Static elimination stop input accepts NPN open collector or contact point signals
• Control output handles NPN open collector with 100 mA maximum at 40 VDC or less
• Air connection port uses Rc 1/8 thread
• Air supply pressure spans 0.1 to 0.5 MPa with 0.2 MPa recommended
• Overvoltage category I and pollution degree 2 apply
• Built-in communication ports remain unavailable; the unit supports remote control communication only

Environmental Tolerance and Interference Resistance

• Operating temperature holds steady from 0 to +40 °C
• Relative humidity ranges from 35 to 85 % RH without condensation
• The shockless resistive coupling design suppresses discharge spikes and protects sensitive products
• Hi-Power I.C.C. control corrects ion balance against environmental drift and interference
• The product carries no formal protection rating, so install it in clean indoor areas

Installation Guide

• Mount the bar between 50 mm and 2000 mm from the target surface
• Keep the 33 tungsten electrodes free of dust and oil for stable corona discharge
• Connect clean, dry compressed air to the Rc 1/8 port at 0.2 MPa for best results
• Wire the 24 to 36 VDC supply and confirm the current draw stays within rated limits
• Route the NPN open collector alarm output to your PLC or indicator for condition monitoring
• Verify ion balance with a charged plate monitor after installation and during scheduled checks
