Drivers For On/off And Stepper Electronic Expansion Valve Management

• Drivers for ON/OFF (pulsed) and stepper electronic expansion valve management
• ON/OFF (pulsed) expansion valve support with 30W max power and coil c.a.
• Temperature analog inputs (NTC, PTC, Pt1000)
• Pressure analog inputs (0-5V, 4-20mA)
• Possibility to broadcast via LAN the pressure signal to multiplexed cabinets
• Alarm management (visual, relay)
• Cool Defrost for defrost time reduction
• Superheat adaptive control
• Standard communication protocol ModBUS-RTU
• Hot Key or Prog Tool Kit connector for a quick and easy programming
• 20VA max power absorption
