M9300-140 Johnson Controls Potentiometer Kit

Overview

The Johnson Controls M9300-140 is an external auxiliary feedback potentiometer kit designed for use with M9300 Series electric non-spring return actuators. It provides 140 ohm position feedback to indicate the position of dampers or valves within HVAC systems, serving as an optional accessory to facilitate seamless retrofitting, safety interfacing, or signaling without needing to replace the controller.

Features

• Backward compatible design allows for an easy retrofit without replacing the controller.
• Provides direct mounting to the actuator without the need for complex damper linkage or crankarms.
• Features snap-on installation with aligned posts for straightforward field setup.
• Designed to warn of or protect against system issues when paired with supervisory or alarm equipment.
