DESCRIPTION

Developed within the framework of industrial conditioner products, the BCI 314 terminal block offers
8 configurable channels

  • voltage, current
  • Strain gages, potentiometer
  • Accelerometer sensor , etc. ...

For each channel:

  • the bridge excitation is + 5.000V or + 10.000V and the power supply is dimensioned to be able to supply 50mA with a regulation factor > 1/1000
  • A current source 4mA to 12 mA / 22V and an AC/DC coupling permit the use of “integrated electronic” sensors
  • Measurement is performed by an instrumentation amplifier with very low drift whose gains are selected with G1 = 1, 10, 50 and G2 = 2, 4, 8, 16 from which a ± 5V FS to ± 6.25mV FS


Each channel is” isolated”, High Common Mode ± 500V, which prevents ground return problems.

The BCI 314 terminal block replaces and improves products BCI 310 and BCI 312.
