Description
The API 4058 G accepts a strain gauge, bridge, load cell,
or a summed input from up to four sensors, and provides
a proportional, non-isolated DC voltage or current output. It
includes filtering and processing to allow effective use of low-
level transducers in the noisy environments found in industrial
applications.
The built-in 115 mA bridge excitation power supply generates a
stable source of excitation voltage to drive from one to four 350
Ω (or greater) bridge type sensors such as load cells, pressure
ripple and noise
transducers and strain gauges The API 4058 G amplifies and
converts the resulting millivolt signal into the selected output.
Input, output, excitation, and zero offset are field configurable,
via external rotary and slide switches. Common ranges are
on the module label. An offset switch is standard for appli-
cations requiring cancellation of sensor offsets or non-zero
deadweights (taring). Zero and span potentiometers allow
calibration of the output.

LoopTracker
API exclusive features include two LoopTracker LEDs (green for
input, red for output) that vary in intensity with changes in the
process input and output signals. These provide a quick visual
picture of your process loop at all times and can greatly aid in
saving time during initial startup and/or troubleshooting.
Output Test
An API exclusive feature includes the test button to provide a
fixed output (independent of the input) when held depressed.
The test output level is potentiometer adjustable from 0 to
100% of output span. The output test button greatly aids in
saving time during initial startup and/or troubleshooting.
The output test is not available with the M01 option. A calibra-
tion resistor switch replaces the test button.
Mounting
The API 4058 G plugs into an industry standard 11-pin octal
socket sold separately. Sockets API 011 and finger-safe API
011 FS allow either DIN rail or panel mounting.
Switches can be pre-set to your specifications.
