Action Instruments MDL-4300-173 Isolating Transmitter

The Action Instruments MDL-4300-173 Isolating Transmitter is a 120 V AC-powered isolating signal conditioner designed to provide galvanic isolation between input and output while delivering a clean, conditioned signal to control systems. Identified as MDL-4300-173 (also cataloged as 4300-173), it belongs to Action Instruments' 4300-series isolating transmitters and signal conditioners, devices used to connect field instruments with PLCs, DCS, or data acquisition systems in industrial environments where ground loops and transient voltages can compromise measurements. The verified power specification is 120 VAC, and the unit is designed for panel- or rack-mount installations where a dedicated AC supply is available, enabling reliable isolation for measurement signals and safe transfer to downstream equipment.
