Adjust Resistance by Command

Think of this controller like a relay board for resistance values. Send a command, adjust the potentiometer position. No manual adjustment required.

Replace the Knob with Code. Resistance control over USB, Ethernet & WiFi

Programmable Digital Potentiometers

Need to adjust resistance values electronically instead of turning a knob? NCD's Programmable Digital Potentiometers allow software control of up to 8 independent potentiometers with 256 programmable tap positions per channel. Available in 10kΩ, 50kΩ, and 100kΩ versions, these controllers let you remotely set resistance values using simple commands sent over USB, Ethernet, WiFi, Bluetooth, RS-232, or MQTT.

Based on the proven MCP42xx0 Series Digital Potentiometers, these legacy controllers continue to be manufactured as long as components remain available. Configure startup positions, store default settings, and control potentiometer values locally or across a network from virtually any software platform.

Available Interfaces

Key Fob Relay Choose the communications method that best fits your application:
  • USB Virtual COM Port
  • Ethernet TCP/IP
  • WiFi
  • Bluetooth
  • RS-232
  • MQTT Cloud Connectivity
Open a TCP socket, send a command, and instantly adjust potentiometer values from anywhere on your network. WiFi and MQTT models can integrate directly with cloud services such as Amazon AWS and other MQTT-compatible platforms.
💡 Relay Pros ProTip:

Need more than resistance control? Add relay expansion modules through the XR Expansion Port to combine programmable potentiometers and relay control in a single system.
