I/O Systems - SD Series I/ORDI01

The RDI01 Redundant low voltage Digital Input module processes up to 16 Digital Input signals. Each channel is individually CH-2-CH isolated and is independently configurable for either 24 or 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 individual input channel parameters such as alarm state, debounce period, SOE settings, etc.

The RDI01 module supports Sequence of Events (SOE) time-stamping to a resolution of 10 msec for 125 VDC inputs and 20 msec for 120 VAC inputs. The SOE event data buffer size is configurable to include up to 50 events.
