SELECTION GUIDE
M700-AL1 2 Wire transmitter, ave. sensing, RMS calibrated.
TYPICAL APPLICATIONS
The M700 series are 2 wire transmitters.
The M700-AL1 converts the A.C. Input current signal to a
4-20mA D.C. Output. The output is directly proportional to the
input signal.
2 Wire transmitters like the M700-AL1, 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-AL1 is average sensing RMS calibrated current
transmitter. 2 Wire transmitters have an advantage over
conventional auxiliary powered transducer, 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 current in energy management systems, switchboards,
generator and telemetery 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.
