MM6010
AC INPUT
ISOLATED TRANSMITTER
DESCRIPTION
The MM6010 provides DC output
voltage or current proportional to an
ACinputsignal.Itisusefulinmeasuring
ACvoltagesorcurrentsandconverting
themtoDClevelsfordrivingcontrollers,
recorders,meters,orotherinstruments.
It utilizes a precision rectifier system to
provide accurate and stable
rectification of the AC input signal. The
module provides an output signal
proportional to the average level of the
inputsignal. It is calibrated assuming a
sinusoidal input signal will be applied.
Other calibrations are available.
The module includes filtering and
conditioning to reduce susceptibility
to transients and noisy operations.
They utilize pulse width modulation
to develop a pulse train with a duty
cycle proportional to the input signal
amplitude.Thispulsetrainiscoupled
through a pulse transformer where
the duty cycle data is converted to a
proportional DC level in the output
circuit.
TYPICALAPPLICATIONS
Monitoring power line or power supply
voltages and currents. Measuring the
output of self-generating process
sensors or transducers which generate
AC signals and measuring current
consumption of electrical devices such
as motors, pumps or heaters.
OPTIONS
The following options are available on
theMM6010:
UAll circuit boards
conformal coated for
protection against
moisture.
DC Power Inverter-isolated 12 or
24 VDC power.
CONTROLS
Two controls, ZERO and SPAN, are
accessible from the top of the module.
CALIBRATION
The MM6010 is shipped pre-calibrated. If
there is a need to re-calibrate, proceed as
follows:
Refer to the instrument’s label to determine
your instrument’s supply voltage and input
and output ranges. Refer to the “Block
Diagram and Pin Connections” for pin
connections.
Connect a precision AC voltage source to
theinput. ConnectaprecisionDCvoltageor
current meter to the output.
Setthe inputtothelowendoftheinput range
and adjust the ZERO control for the low-end
output voltage or current. Raise the input to
fullscaleand adjust the SPAN control for full
scaleoutput. Repeatuntilbothreadingsare
correct.
