MM7010 &
MM7010 ISO
FREQUENCY INPUT
TRANSMITTERS
DESCRIPTION
The MM7010 is used to provide a DC
output voltage or current proportional to
the frequency of the input signal. It is
useful for measuring speed of motor,
conveyors, or other devices that can
createaperiodicsignalproportionaltothe
desired function. The wide range of input
sensitivityallowstheMM7010tobedriven
from low level magnetic pickups as well
as logic level signals.
A threshold adjustment sets the minimum
input amplitude the module will process.
Thisallows theuser totrade offsensitivity
versus noise rejection. An optional pullup
resistor (Option P) permits use with
contact-closure or open-collector inputs.
OPTIONS
The following options are available on
theMM7010&MM7010ISO:
P10 kilohm pullup resistor for use
with open-collector or contact-
closure inputs.
UAll circuit boards conformal coated
for protection against moisture.
DCPower
Inverter-isolated 12 V or 24 VDC
power.
CONTROLS
Three controls, ZERO, SPAN and
THRESHOLD,areaccessiblefromthetop
of the module.
CALIBRATION
The MM7010 is shipped with ZERO and
SPAN pre-calibrated. The user need only
adjust the THRESHOLD for the desired
sensitivity.
The THRESHOLD adjustment allows the
module to be made insensitive to the line
frequency pickup or other noise signals
whose levels are below the threshold
setting.Turningthiscontrolfullyclockwise
reduces the threshold to zero and makes
the input most sensitive.
Toadjust, settheinput atabout half-scale
frequency and at about 25% of its normal
amplitude.Turnthe THRESHOLDcontrol
fully clockwise then, while monitoring the
output, turn the control counterclockwise
until the output drops (suddenly) to its
low-end value. NOTE: If the output does
not drop, leave the control fully
counterclockwise.
Tore-calibrateZEROandSPAN,proceed
as follows:
Refer to the instrument's label to determine
your instrument's supply voltage and input
andoutputranges.Refertothe“BlockDiagram
and Pin Connections” for pin connections.
Connect a calibrated frequency source to
theinputoftheinstrument.(OptionP,ifnoted
on the label, indicates a pullup resistor has
been added for use with switch-closure or
open-collectorinput(SeeBlockDiagramand
Pin Connections).
Set the input frequency to the low end of the
input range and adjust the ZERO control for
thelow-end oftheinput rangeandadjust the
ZERO control for the low-end output voltage
or current. Increase the input frequency to
fullscaleand adjusttheSPANcontrolfor the
full-scale output. Repeat until both readings
are correct.

MOUNTING
Themoduleisdesignedtoplugintoastandard
8-pin relay socket. (MP008) is a molded
plastic socket suitable for mounting on a flat
surface or snap into a 2¾ inch wide PVC
track (TRK48).
A spring hold-down clip (CLP1) is available
for installation where vibration may be a
problem.
A DIN rail mounted socket (DMP008) is
available for 35mm symmetrical DIN rail.
A Killark HK Series explosion-proof housing
with dome and 8-pin socket is available
(HKB-HK2D-8).
WARRANTY
TheMightyModuleSeries of productscarry
a limited warranty of 10 + 5 years. In the
event of a failure due to defective material
or workmanship, during the 10 year period,
the unit will be repaired or replaced at no
charge. For a period of 5 years after the
initial 10 year warranty, the unit will be
