Scientific Columbus VT-110A2 Voltage Transducer

The VT-110A2 Voltage Transducer from Scientific Columbus (AMETEK) is a compact voltage-to-current transducer designed to convert a sensed voltage up to 150 VAC into a low-level 0–1 mA DC signal for instrumentation and control systems. It accepts an input range of 0–150 VAC and delivers a 0–1 mA DC output that can drive a load of 0–10 kΩ, enabling safe, remote monitoring of higher voltages in industrial environments. Powering this device typically uses a standard mains supply around 120 VAC (±10%), with multiple catalog references listing the model as VT-110-A2, VT-110A2, or VT-110 A2S; it is also noted in some sources under the Exceltronic family. Common applications include panel instrumentation, data acquisition, and process-control loops where a high-voltage signal must be represented by a low-current, easily readout signal for controllers and recorders, making it a straightforward choice for engineers needing direct voltage-to-current transduction from Scientific Columbus equipment.
