Digital potentiometer current source 4-20mA

Digital potentiometers are control devices that produce an analog output between 4-20mA.

• Microprocessor-based
• Analog output: 4-20mA
• Entering the menu and controlling the analog output via the front keys
• Control of the analog output via digital inputs
• Adjustable upper and lower scale levels
• Adjustable upper and lower limits for SET
• Separate function selection for the front keys and digital inputs for controlling the analog output
• Password protection
• SECU setting for enabling/disabling access to the SET configuration menu
• High accuracy
• EEPROM memory for storing settings
• Easy connection with plug connectors
