| SELECTION GUIDE M700-VL1 2 Wire transmitter, ave. sensing, RMS calibrated. TYPICAL APPLICATIONS The M700 series are 2 wire transmitters. The M700-VL1 converts the A.C. input voltage signal to a 4-20mA D.C. Output. The output is directly proportional to the input signal. 2 Wire transmitters like the M700-VL1, obtain the power to operate from the 4-20mA output circuit to which they are connected, and therefore require no separate auxiliary supply. The M700-VL1 is average sensing RMS calibrated current transmitter. 2 Wire transmitters have an advantage over conventional auxiliary powered transducers, because no separate auxiliary is required, savings in the cost of providing a separate auxiliary supply and wiring are made. The above units are used to measure voltage in energy management systems, switchboards, generator and telemetry controls. Isolation of 4kV is provided between the input and output signal, allowing the output to be fed to conventional analogue meters, digital meters, PLC, and computer systems.
