DC INPUT
MULTIPLIER
TRANSMITTER
DESCRIPTION
The MM4410modules provide a DC output
voltage or current proportional to the
product of two DC inputs. Typical input
ranges are 4/20 mA, 10/50 mA, 0-1 V, 0-
5 V, and 0-10 VDC. Other ranges are
available down to minimum spans of 1 V
or 1 mA DC.
The two inputs are emplified and applied
to a complex integrated circuit which
performs the multiplication function. The
resulting product is applied to an output
stage which provides the final DC voltage
or current output. Zero and span
adjustments in the output circuit allow
precise calibration.
For current inputs, internal shunt resistors
creat DC voltage levels at the amplifier
inputs. Input offset capability permits
multiplication of offset inputs such as 4/
20 mA.
Standard calibration provides the output
at full scale (100%) when both inputs are
at full scale (100%). Other calibrations are
available.
OPTIONS
U
All circuit boards conformal coated for
protection against moisture
DC Power
12 V or 24 VDC power
CONTROLS
The MM4410 modules contain two calibration
controls, ZERO and SPAN. Both are available
at the top of the module.
CALIBRATION
The modules are shipped precalibrated and
does not normally need adjustment. If you
need to recalibrate, proceed as follows:
Monitor the output with an accurate meter
and insert input signals into both inputs. Set
Input A to its minimum level, Input B to full
scale. Adjust the ZERO control for the
proper output. Increase Input A to full scale
and adjust the SPAN control for the proper
output. Repeat the procedure, the controls
may interact slightly.
MOUNTING
The module is designed to plug into a stan-
dard 8-pin relay socket. (MP008) is a molded
plastic socket suitable for mounting on a flat
surface or in a 2 ¾ inch wide PVC snap track
(TRK48). Use (CLP1) hold down clip, if
needed. A Killark HK Series explosion-proof
housing with dome and 8-pin socket is avail-
able (HKB-HK2D-8). A DIN rail socket
(DMP008) is available for 35mm symmetrical
DIN rail.
WARRANTY
The Mighty Module Series of products carry
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
repaired, if possible, for a cost of 10% of
the original purchase price.
Relays are not covered by the warranty.
