What is the Wago 750-1491?

This analog input module directly connects to two resistor bridges.

The bridge voltage U D and supply voltage U ref of the respective bridge are digitized with a resolution of 16 bits.

The two input channels for the respective resistor bridge are available as two 16-bit values for additional processing.

The bridge detuning can be determined from the quotients of the two measurement values U d and U ref .

Functional galvanic isolation is provided between both channels.

The internal supply voltage is derived from the system supply.

The supply of a separate 24 V field voltage is not necessary. The voltage supplied via the power jumper contacts is looped through to downstream I/O modules.

The shield connects to the DIN-rail.

The module is parameterized via GSD file, e! COCKPIT or WAGO-I/O- CHECK .
