ABB DI810 digital input module

ABB DI810 digital input module

Electrical parameter
Input channels: 16.
Input voltage range: “0” level is -30… +5V, “1” level is 15… 30V, rated input voltage is 24V DC.
Input current: 6mA at 24V.
Input impedance: 3.5kΩ.
Rated insulation voltage: 50V.
Dielectric test voltage: 500V AC.
Power consumption: Typical 1.8W.
Current consumption: +5V module bus 50mA, +24V module bus 0mA, +24V external 0mA.
Signal processing parameter
Signal type: sinking type.
Filter time: 2, 4, 8, 16ms can be selected.
Isolation mode: Group and ground isolation, divided into 2 groups, each group of 8 channels, each through the limited current element, EMC protection element, input status indicator LED and light isolation barrier. Each group has a process voltage monitoring input, and if the voltage disappears, the channel error signal can be read through the module bus.
Communication related: Support RS-485 (Modbus RTU) communication protocol.
