API Module Power Options

• DC Voltage Input: 0-5 mV to 0-1200 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

The APD 4058 accepts an input from a strain gauge, bridge type sensor, load cell, or pressure transducer. It filters, amplifies, and converts the resulting millivolt signal into the selected DC voltage or current output that is linearly related to the input. The output is not electrically isolated.The adjustable excitation power supply generates a stable source of voltage to drive your sensor. Input, output, excitation and zero offset are field configurable, via external rotary and slide switches. Offsets up to ±100% of span can be used to cancel sensor offsets or non-zero dead weights (taring).

Strain Gauge Input Ranges
Minimum range: 0 to 5 mV
Maximum range: 0 to 1200 mV
Minimum sensitivity: 0.5 mV/V
Maximum sensitivity: 120 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
