PRODUCT INFORMATION
Product Overview
The ABB DI840 3BSE020836R1 is a 16-channel 24 V d.c. Digital Input Module for the S800 I/O platform. It supports single or redundant architectures in distributed automation setups. Each channel operates as a current-sinking input drawing 7 mA at 24 V d.c. Optical isolation barriers and EMC protection components protect internal circuitry from field interference.
Integrated sequence of events recording collects digital transitions with 1 ms resolution. The internal event queue holds up to 257 events with an integrated shutter filter. Field transducer power is supervised and current-limited with one output per two input channels. Diagnostic LEDs on the front indicate module errors, warnings, run state, and individual channel status.
