The DI04 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 DI04 module does not support Sequence of Events (SOE) Features and benefits 16 individually CH-2-CH isolated DI channels supporting: 48 VDC Digital Input signals Configurable contact debounce time up to 255 msec DI04 module can sink or source I/O current Input Status LEDs on module frontplate Galvanic isolation of 1500 V for up to 1 minute DI04 does not support SOE
