- Terminal Definition Overview
の 16 channels are divided into two groups:
Group1: DI0～DI7
Group2: DI8～DI15
Each group has an independent COM terminal, supporting wiring for NPN (sinking) / PNP (sourcing) センサー.
- Phase-out & Upgrade Replacement Solution
⚠️ 3DI476.6 has been officially discontinued by the manufacturer. No new original units available; only surplus stock or used modules are on the market.
Recommended Functional Replacement on X20 Platform
X20DI4371 (16から, 24VDC, 集団隔離, functional equivalent to 3DI476.6)
主な違い:
- Hardware racks are incompatible: X20 modules cannot be plugged directly into System 2005 ラック. Full controller platform upgrade is required (CPU + entire backplane).
- プログラム: Project migration and IO address remapping are needed; B&R Automation Studio supports variable migration.
Spare Part Temporary Solution
Only surplus new stock or refurbished modules can be sourced. Verify production year and intact terminal blocks before purchase.
- 典型的なアプリケーションシナリオ
Digital signal acquisition for machine tools, 包装機械, material handling conveyors, プラスチック & rubber equipment: proximity sensors, 光電センサー, 押しボタン, リミットスイッチ, relay contact signals.
- Common Troubleshooting Guidelines
- No signal on channel: Measure 24V supply and COM wiring; verify sensor type (NPN/PNP) matches COM wiring configuration.
- Signal flickering / 誤ったトリガー: Apply cable shielding, reduce line voltage drop, adjust input filter time parameters in Automation Studio.
- No channel faults reported but all channels inactive: Check backplane power supply and ensure module bus latches are fully engaged.
- Model Selection Pitfalls
❌ X20 modules cannot be inserted into System 2005 racks directly;
❌ Evaluate overall CPU upgrade costs for large-scale renovation of legacy machines; prioritize spare parts stocking for small equipment;
✅ Do not select 3DI476.6 for new projects; uniformly adopt X20 series.

- Quick Selection Comparison
- 3DI475.6 vs 3DI476.6
同じチャンネル数; the only difference lies in input filter time:
3DI475.6: 12MS (for general signals)
3DI476.6: 1.2MS (for high-speed counting & high-frequency proximity sensor signals)
- Slot Occupancy: 3DI476.6 occupies 2 backplane slots, reserve sufficient slots when selecting backplanes.
