ABB DI830 16‑Channel Digital Input Module for S800 I/O System

Technical Specifications Model: DI830 System Compatibility: ABB S800 I/O system, AC800M controller Input Channel Quantity: 16 digital input channels Input Signal Type: 24 V DC sinking input Input Voltage Operating Range: 18‑30 V DC Input Current: 6 mA typical at 24 V DC Isolation Structure: Two groups of 8‑channel group‑wise galvanic isolation Digital Filter Range: Configurable 0‑100 ms filter time SOE Function: Sequence‑of‑event time‑stamping function Mounting Type: S800 I/O rack plug‑in module, DIN‑rail mounting Operating Temperature: 0 ℃ to +55 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE, UL

Functional Features 16‑channel 24 V DC sinking digital input for field‑site switch‑contact signal acquisition. Two groups of 8‑channel group‑wise galvanic‑isolation structure suppresses inter‑group interference. Configurable 0‑100 ms digital input filter eliminates field‑site interference pulse and contact bounce. Supports SOE sequence‑of‑event time‑stamping for recording field‑site state‑change event sequence. Each channel corresponds to front‑panel LED indicator for real‑time input‑status display. Built‑in comprehensive self‑diagnosis function monitors process‑power‑supply supervision, event‑queue overflow and time‑synchronization loss fault. Supports hot‑swap operation on S800 I/O rack under permitted maintenance condition.

Application Scenarios S800 I/O system DI830 digital‑input module spare‑part replacement. Process‑industry control cabinet field‑site relay‑contact, limit‑switch and interlock‑signal acquisition. AC800M control project requiring SOE event‑sequence recording function for fault post‑analysis.

Installation Requirements Insert DI830 module into designated slot of S800 I/O DIN‑rail rack, lock side‑part spring locking buckle. Connect field‑site 24 V DC sinking‑type switch‑signal cables to front‑side screw‑type terminals, tighten terminals to specified torque. Set digital filter time and SOE function parameters via AC800M engineering configuration tool. Complete cabinet protective earthing complying with S800 I/O system grounding specification. Separate field‑signal cables and high‑power power cables inside control cabinet. Reserve ventilation heat‑dissipation space around module slot. Ambient operating temperature must keep within 0 ℃ ~ +55 ℃ without condensation.
