# AN-TD4-013 - How to use a panel meter and potentiometer to provide external speed display and control

## Using a Panel Meter with TD400

AN-TD4-013

This document shows how to connect field devices that require more current than the 24VDC, 60mA source provided by the TD400.

This document shows how to setup a panel meter and external potentiometer to interface with the TD400 in order to show drive speed and control output speed. This setup would provide an alternative to an external keypad and maintain the enclosure rating.

Example wiring diagrams are provided.
