LMI Milton Roy 28749-11 Current Frequency Converter

LMI Milton Roy 28749-11 Current Frequency Converter is an industrial interface device that converts a current input to a frequency output for use with compatible control equipment. The unit operates from 120V and draws about 0.2A, making it suitable for integration into standard electrical panels within process or automation environments. The model number 28749-11 uniquely identifies this converter within Milton Roy’s lineup, ensuring correct pairing with other LMI/Milton Roy components and control systems. By translating a current signal into a frequency reference, this converter enables analog or current-based control loops to drive frequency-responsive actuators or controllers, supporting precise, signal-compatible interfacing in automation architectures. Its compact form and straightforward electrical specification can simplify installation in control cabinets or equipment housings where space and power are considerations. Typical use cases involve systems that require a frequency-based input downstream from a current-driven signal, such as automation loops that monitor process variables and adjust outputs accordingly. When integrating, ensure the power supply is 120V and that downstream devices are compatible with the converter’s frequency output characteristics to maintain reliable control behavior.
