ABB DI820 Digital Input Module product feature
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.
The DI820 is an 8 channel 120 V a.c./d.c. digital input module for the S800 I/O. This module has 8 digital inputs. The a.c. input voltage range is 77 - 130 volt and the input current is 10 mA at 120 V a.c. The d.c. input range is 75 - 145 V and the input current is 2.8 mA at 110 V. The inputs are individually isolated.
Every input channel consists of current limiting components, EMC protection components, input state indication LED, optical isolation barrier and an analog filter (6 ms). Channel 1 can be used as voltage supervision input for channels 2 - 4, and channel 8 can be used as voltage supervision input for channels 5 - 7.
If the voltage connected to channel 1 or 8 disappears, the error inputs are activated and the Warning LED turns on. The error signal can be read from the ModuleBus. This supervision can be enabled/ disabled with a parameter. If the error inputs are disabled channel 1 and 8 can be used as normal input channels.
The input channels can be digitally filtered. The different filter times that can be achieved are 2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and pulses longer than 3, 6, 12 and 24 ms will get through the filter.
Five different types of MTUs can be used. The TU831/TU851 Extended MTU, TU811/TU811V1 Compact MTU, and TU813 Compact MTU provide two terminals per channel. The TU839 Extended MTU provides two terminals per channel and one terminal for the outgoing sensor supply.
