Description

The API 4059 G accepts a strain gauge, bridge, load cell, or a

summed input from up to four sensors, and provides a propor-

tional, 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

full 3-way (input, output, power) isolation makes this module

useful for ground loop elimination, common mode signal rejec-

tion or noise pickup reduction.

The 120 mA adjustable bridge excitation power supply gener-

ates a stable source of excitation voltage to drive from one to

four 350 W (or greater) bridge type sensors such as load cells,

pressure transducers and strain gauges and amplifies and

converts the resulting millivolt signal into the selected output.

Sense lead circuitry is included to cancel the effects of leadwire

resistance, if required.

Input, output, excitation and zero offset are field configurable,

via external rotary and slide switches. Common ranges are on

the module label. Offsets up to ±100% of span can be used to

cancel sensor offsets or non-zero deadweights (taring). Non-

interactive zero and span simplifies calibration.

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 output test button greatly aids in saving time during initial

startup and/or troubleshooting. The test output level is potenti-

ometer adjustable from 0 to 100% of output span.

The output test is not available with the M01 or M02 options. A

calibration resistor switch replaces the test button.

Mounting

The API 4059 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.
