I/O Systems - SD Series I/ODI04

The DIØ4 digital input module processes up to 16 individual Digital Input signals. Each channel is individually CH-2-CH isolated and supports 48 VDC inputs. FC 221 (I/O Device Definition) sets DI module operating parameters and each input channel is configured using FC 224 (Digital Input CH) to set input channel parameters such as alarm state, debounce period, etc.

The DIØ4 module does not support Sequence of Events (SOE)
