ABB DI818 3BSE069052R1 Digital Input 24V 32 Ch

ABB DI818 3BSE069052R1 is a 24V digital input module with 32 digital input channels. The input voltage range is 18 - 30V DC and the input current is 4.3mA at 24V. The input channels are divided into two groups of 16 channels each and are independently isolated from each other. Each group has a voltage monitoring input. Each input channel contains current limiting components, EMC protection components, input status indication LEDs and optical isolation barriers. When the process voltage disappears, the voltage monitoring input will issue a channel error signal, which can be read via the ModuleBus.

Fuctions & Features

• It has 32 channels, suitable for 24V DC current sink input, which can meet the needs of a large number of digital signal inputs.

• The 32 channels are divided into two groups, each with 16 channels, and the two groups are isolated from each other, and each has voltage monitoring. This design enhances the electrical independence between channels and can effectively prevent interference. At the same time, voltage monitoring can provide timely feedback on voltage abnormalities.

• It can monitor the input voltage in real time. When the voltage disappears, a channel error signal will be given, and the signal can be read through ModuleBus.

• The input signal can be filtered to help remove signal impurities.
