DI885 Digital Input Module
The DI885 Digital Input Module has 8 channels for 48 volt d.c. digital inputs with or without open-circuit monitoring (wire break supervision), or 24 volt d.c. electronic inputs without open-circuit monitoring; and sequence of events (SOE) handling capabilities. The sequence of events timestamp has a resolution of 1 ms for each input channel. The inputs are arranged in one group of 8 channels. Each input channel provides current limiting, EMC protection, input state LED indicator, and optical isolation from the ModuleBus. The DI885 also has the capability to monitor an internal or external sensor power supply (60 V d.c. max.).
