• DC Voltage Input: 0-5 mV to 0-400 mV
• DC Output: 0-1 V, 0-5 V, 0-10 V, +/- 5 V, +/- 10 V, 4-20 mA, etc.
• Strain Gauge Bridge Excitation: 1 to 10 VDC
• Field-Configurable by User
• Non-Interactive Zero & Span Adjustment Pots

The API 4059 G accepts a strain gauge, bridge, load cell, or a summed input from up to four sensors, and provides a proportional, 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 rejection or noise pickup reduction.

The 120 mA adjustable 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 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). Noninteractive zero and span simplifies calibration.

Input
Field Rangeable; Via external rotary & slide switches
Minimum range: 0 to 5 mV
Maximum range: 0 to 400 mV
Minimum sensitivity: 0.5 mV/V
Maximum sensitivity: 40 mV/V
Millivolt output range is determined by the sensitivity of the sensor (mV/V) and the excitation voltage applied
mV/V sensitivity X excitation voltage = total mV range
