PRODUCT INFORMATION
Product Overview
The ABB DI820 3BSE008512R1 is an 8-channel digital input module engineered for the S800 I/O platform. It interfaces field devices operating at either 120 V AC or 110 V DC nominal levels. Each input channel features galvanic isolation, EMC protection circuitry, current limiting elements, and an integrated analog input filter. The module transmits field device states directly to the controller via the standard ModuleBus backplane.
This module provides process voltage supervision capabilities using designated input channels. Channel 1 serves as voltage supervision for channels 2 through 4, while channel 8 monitors channels 5 through 7. If the field power supply drops, the module asserts an internal error flag and illuminates the front Warning LED. Diagnostic data and module status remain accessible across the communication bus.
