Wilkerson Instrument MM4380A Data sheet
DESCRIPTION
The MM4380A provides a DC output
proportional to a DC input. The output is
fully isolated from input, line power and
ground. The unit is useful in eliminating
ground loops and common mode
signals.
Input and output ranges are usersettable. Each may be voltage or current,
with or without offset. The output response
may be normal or reverse-acting. A fullylabeled set of jumpers selects the input
and output ranges. The MM4380A is
identical in size and fully interchangeable
MM4380A
DC INPUT, FIELD RANGEABLE
ISOLATED TRANSMITTER
FEATURES
· Allows Inputs to ±256 V or
±100 mA
· 15 mV or 0.8 mA Minimum
Input Span
· Size, Pinouts and
Performance Identical to
MM4300 & MM4300A
· User-Settable Input and
Output Ranges
with fixed-range modules such as the
MM4300 and MM4300A.
All Wilkerson products are designed with
RFI filters and lightning protection to
reduce susceptibility to electrical noise
and damage by lightning. It utilizes a
feedback VCO to develop a pulse train
with a duty cycle proportional to the input
signal amplitude. This pulse train is
coupled through a pulse transformer to
the output circuitry, where the duty cycle
data is converted to a proportional DC
output level.
· Fully Labeled Jumper
Positions for Easy Range
Settings
· Provides a Fully Isolated DC
Output Proportional to DC
Input
· Choice of Power Options
· Permanent Warranty
TYPICAL APPLICATIONS
Eliminates ground loops and common
mode signals. Use for voltage/current
scaling and conversion with isolation for
buffering and noise reduction. Singleunit replacement module provides field
rangeability for all normal input and output
ranges.
