Absolute Process Instruments API4300GD24 Signal Conditioner

The Absolute Process Instruments API4300GD24 is an isolated, DC-to-DC signal conditioner and transmitter that accepts a 4–20 mA input and provides an isolated 4–20 mA output, preserving signal integrity while guarding control equipment from process-loop noise. It is powered from 9–30 VDC (24 VDC nominal in many installations) and delivers galvanic isolation up to 2000 V between input and output to minimize ground loops and EMI issues. The unit uses screw-terminal input and output connections and includes LoopTracker LEDs and an output-test push button for quick verification, with an operating temperature range of -10 to 60 C for rugged industrial use. Designed for reliable conditioning and isolation of current-loop signals, this API 4300 G D device enables clean transmission to PLCs, data acquisition systems, or SCADA without disturbing the sensor circuit.
