ABB DI820 3BSE008512R1 Digital Input 120V A.c. 8 Ch

ABB DI820 3BSE008512R1 is a digital input module with 8 digital input channels that can accept AC and DC input signals. The AC input voltage range is 77-130V, and the input current is 10 mA at 120V AC; the DC input range is 75-145V, and the input current is 2.8 mA at 110V DC. Each input channel is independently isolated, and some channels can be used as voltage monitoring inputs for other channels. When the voltage of a specific monitoring channel disappears, the error input will be activated and the warning LED will be lit, and the error signal can be read from the module bus.

Fuctions & Features

• 8 channels for 120 V a.c./d.c. inputs

• Individually isolated channels

• Voltage supervision of field input power

• Input status indicators

• Signal filtering

• ​​​​​​It has signal filtering function, digital filtering time is optional (2, 4, 8, 16 milliseconds), and the analog filter opening/closing delay is 5/18 milliseconds, which can effectively filter interference signals.

• It has the voltage monitoring function of the on-site input power supply, such as channel 1 can monitor channels 2-4, and channel 8 can monitor channels 5-7 to ensure the normal input power supply.

• The sensor power supply can be current limited through MTU to protect the safety of the equipment.
