M100-VR1 1 ph. auxiliarypowered true RMS sensing RMS calibrated
M100-VA3 3 ph. self powered average sensing RMS calibrated
M100-VL3 3 ph. auxiliary powered average sensing RMS calibrated

Typical Applications
The M100 series voltage transducers are designed to measure A.C. voltage in single and three phase systems. They convert the A.C. signal to a D.C. output that is directly proportional to the input.
The M100-VA1 VA3 are self powered (no auxiliary required), average sensing, RMS calibrated voltage transducers with mA or voltage outputs.
The M100-VL1 VL3 are average sensing RMS calibrated, live zero voltage transducers. Auxiliary is required to provide power so that a 4mA output signal is present when the input is zero.
The M100-VR1 is true RMS sensing and RMS calibrated allowing measurements of distorted waveforms up to 9th harmonic with a crest factor of 5. The VR1 is typically used in voltage measurement where distorted waveform is common such as thyristor drives.
These transducers are used to measure voltage in energy management systems, switchboards, generator and telemetery controls.
Isolation of 4kV is provided between the input and the output, allowing the ouput to be fed to conventional analogue meters, digital meters, PLC, and computer systems.

M100 Special AC Voltage Transducer

Selection Guide
M100-VS1 Suppressed zero voltage auxiliary powered
M100-VX1 1 ph. aux. powered ave. sensing RMS calibrated
M100-VX33 ph. aux. powered ave. sensing RMS

Typical Applications
The M100-VS1 is a self powered voltage transducer.
The suppression allows the transducer to accurately measure a voltage system over a narrow band either side of a nominal voltage.
The range can be between ± 10% to ± 30% which can be specified when ordering.
Typical application is to display the voltage on an analogue meter with an expanded scale. This allows the user to read small changes in the voltage in a single or three phase system.
The output could also be fed to a computer that could then control the voltage of the system, to ensure that it stays within the narrow band.
The M100-VX1 and M100-VX3 are essentially the same as the M100-VA1 and M100-VA3, but have auxiliaries which allow the working range to be 0-125% rather than 10-125%.
Used where the average sensing of voltage is required from 0 to 125% of the nominal voltage.

M100 DC Current or Voltage 4kV or 1.5kV Isolation Transducers

Selection Guide
M100-DA1 DC current input 4kV isolation
M100-DV1 DC voltage 20mV..11.9V input 4kV isolation
M100-DV2 DC voltage 12V..600V input 4kV isolation

M100-DA1I DC current input 1.5kV isolation
M100-DV1I DC voltage 20mV..11.9V input 1.5kV isolation
M100-DV2I DC voltage 12V..600V input 1.5kV isolation

Typical Applications
These isolators isolate the DC input signal from the DC output signal, which is directly proportional to the input signal. There are two levels of isolation offered, the M100-DA1/DV1/DV2 have 4kV isolation and the M100-DA1I/DV1I/DV2I have 1.5kV isolation.
A wide range of both D.C. Current and voltage inputs are offered.
Typically these isolators can be used to prevent earth loops, which occur when an earthed measuring source is connected to a computer or data logger that is also earthed. Another common use is to provide isolation on the inputs to a PLC. All of the above isolators have either A.C. or D.C. auxiliaries which means they have an advantage over loop powered units, in that if for any reason the output lead should become disconnected, the input will not be saturated.

M100-DM3 One input three outputs

Typical Applications
The M100-DM3 takes 1 DC input signal and provides 3 isolated outputs all directly proportional to the input. The outputs can all be of the same D.C. value or different. Typically this product is used to prevent earth loops between measuring devices.

An M100-DM3 could have its input signal provided by a M100-WA4 watt transducer with 4-20mA output.
The 3 outputs from the M100-DM3 could be as follows.
Output A: 4-20mA fed to a PLC.
