Digital potentiometer current source 4-20mA

Digital potentiometers are control devices that generate analog output between 4-20mA values.

• Microprocessor-based
• Analog output: 4-20mA
• Menu input and analog output control with front buttons
• Analog output control via digital inputs
• Adjustable upper and lower scale levels
• Adjustable SET upper and lower limits
• Separate function selection for front buttons and digital inputs for analog output control
• Password protection
• SECU setting to enable/disable SET adjustment menu input
• High accuracy
• EEPROM memory for saving settings
• Easy connection with plug connectors
