Wago 750-491 WAGO I/O-SYSTEM 750 Analog Input Module
1-Channel Analog-Input Strain gauge, Signal: Resistor bridge Strain gauge, Conversion time: 500 ms, Resolution: 16 Bit, Sensor supply voltage: DC 5 V, Signal voltage UD: -15..+15 mV, Signal voltage Uref: 2-6 V, Internal resistance: >200 kOhm (Uref), >1 MOhm (UD)
The I/O module enables the direct connection of a resistor measurement bridge.
The bridge voltage VD and supply voltage Vref of the bridge are digitized with a resolution of 16 bits.
The two input channels for the resistor bridge are available as two 16 bit values for further processing.
The result of measurement can be calculated by the formula: Measured value = VD / Vref.
Field and system levels are electrically isolated.
