DSAI110 57120001-DP ABB DSAI110 POINT INPUT MODULE

Product Description:

When resistance thermometers are used, a constant current must flow through the measuring resistor in order to create the necessary voltage drop for the evaluation. For this purpose, the basic unit 07 KT 94 provides a constant current sink, which is multiplexed to the 8 analog channels. The following figure shows the connection of Pt100 resistance thermometers in 2-wire configuration.Measuring ranges -50°C...+400°C and -50°C...+70°C with Pt100 as temperature sensor in 3-wire configuration Thefollowing figure shows the connection of Pt100 resistance thermometers in 3-wire configuration.

Product's Character:

The trigger of the self-protecting mechanism is displayed by the red LED Ovl as long as the overload is present. In the PLC system an error message is then stored (FK4, error number 4). The following figure shows the connection of a 3-wire sensor powered by 24 V DC and of a 2-pole sensor powered
electrically isolated. Both sensors work as active current sources 0...20 mA. It has to be taken into consideration, that in this application the M terminal of the basic unit 07 KT 94 is the reference potential. AGND1 is not dimensioned for carrying the sum of the sensor currents.
