T-VL Loop Powered Voltage Transducer
Model T-VL

T-VL Loop Powered Voltage Transducer

The T-VL voltage transducer converts an ac voltage input into a load independent 4 to 20mA dc signal capable of driving a number of independent instruments.
Accurate measurement assumes a sinusoidal input waveform.
Power for the unit is derived from the loop current.
