8CH Full Individual Isolation High Voltage DI: Every single channel independent optocoupler isolation, channel-to-channel & channel-backplane isolation up to 250V rated withstand voltage; AC input range:164~264VAC(230V nominal,7.6mA@230VAC), DC input range:175~275VDC(220V nominal,1.6mA@220VDC), sinking input logic。
Built-in Hardware Input Filter: Integrated signal filter suppresses field surge pulse & contact bounce interference, avoid false triggering caused by long-distance high-voltage cable induced noise。
Multi-layer Per-channel Protection: Each channel equips current-limiting circuit, reverse polarity prevention, EMC surge absorption component, effectively resist wrong wiring and field high-voltage spike damage。
Field Power Voltage Supervision: Real-time monitor field-side input power supply status, upload power abnormal alarm to DCS controller automatically。
Single Channel Independent LED Indicator: Front panel dedicated LED for each input channel, intuitive real-time signal status display, fast on-site fault diagnosis without measuring tools。
Modulebus Hot Swap Function: Direct plug into S800 standard I/O rack, communicate with AC800M via backplane bus; online replace module without cutting rack power, DCS auto identify module address after installation。
Conformal Coated PCB: Three-proof anti-moisture, anti-dust, anti-corrosion coating, adapt to dusty, high-humidity harsh industrial control cabinet environment。
