Digital potentiometer current source 4-20mA

Digital Potentiometers are control devices that produce an analog output within the range of 4-20mA values.

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