Technical FAQs

What voltage level does DI810‑1 expect for digital inputs?
Standard 24 V DC industrial logic; both sinking and sourcing configurations supported.
How many inputs does the module provide?
It offers 16 discrete digital input channels.
Is the module hot‑swappable?
Within properly designed S800 racks and terminal bases, yes — it supports modular replacement without shutting down the entire system.
Can I mix sink and source wiring on the same module?
No — the module must be wired consistently either in all-sink or all-source configuration for correct operation.
What kinds of environments is DI810‑1 suited for?
Industrial settings including manufacturing floors, process plants, utilities — tolerant to vibration, EMI, and typical shop-floor conditions.
Does it support diagnostic feedback?
Yes — module status and individual channel integrity can be monitored through the control system diagnostics.
Can I pair it with analog modules in the same rack?
Absolutely — the S800 modular architecture permits mixed I/O racks including digital, analog, and communication modules.
What kind of mounting does it require?
Standard DIN‑rail mounting or S800 backplane base, depending on your rack design.
Is the module suitable for safety-rated applications?
DI810‑1 is intended for general-purpose discrete I/O. For safety-rated applications, dedicated safety-certified modules should be used.
What is the typical response time for input detection?
Response occurs at each system scan cycle, sufficient for timely detection of switch events, sensor pulses, or discrete signals in automation logic.
