Ohio Semitronics SCE-003 Voltage Transducer 0-50mV Input 4-20mA Output

Ohio Semitronics SCE-003 Voltage Transducer 0-50mV Input 4-20mA Output

The Ohio Semitronics SCE-003 is a single-phase voltage transducer that converts a low-level DC millivolt input signal (0–50mV) into a proportional 4–20mA current loop output. This type of signal conditioning is used to interface low-level voltage sources — such as shunts, thermocouples, or bridge sensors — with standard process control instrumentation, PLCs, and data acquisition systems that accept 4–20mA analog inputs. The unit is housed in a compact, panel-mountable green metal enclosure manufactured by Ohio Semitronics, Inc. of Hilliard, Ohio, and is made in the USA.

Applications

Ohio Semitronics SCE-series transducers are standard signal-conditioning components in industrial process control and power monitoring systems. The SCE-003's 0–50mV input range makes it well suited for use with DC current shunts — where the millivolt drop across the shunt represents a proportional current — converting that low-level signal into the 4–20mA standard used by PLCs, DCS controllers, panel meters, chart recorders, and SCADA systems. They are commonly found in energy monitoring panels, motor control centers, and industrial automation installations where voltage or current measurements need to be transmitted over distance or interfaced to standard analog inputs. Ohio Semitronics has been producing power transducers and signal conditioners since the 1970s for the utility, manufacturing, and process industries, and the SCE series remains a recognized product line in those sectors.
