Modular Expandable I/O Layout: Flexible collocation of digital input/output & analog input/output sub-modules, single base unit supports up to 32-channel 24VDC scanning input, customizable mixed DI/DO/AI/AO configuration per field requirement.
Profibus Standard Fieldbus: Native Profibus DP/DPV1 communication interface, baud rate 9.6kbps~12Mbps adjustable, seamless data interaction with AC800F main controller, compatible Advanced Fieldbus100 bus protocol.
Multi-layer Redundancy Design: Optional dual redundant power supply, redundant fieldbus trunk and independent channel redundancy configuration; supports bus media monitoring, automatic fault switching and real-time fault alarm reporting.
Per-channel LED Fault Diagnosis: Independent status indicator for every single I/O channel and bus port, rapid on-site fault pinpoint without extra testing instrument.
Configurable Fail-safe Output: All output channels can be preset to freeze status or fixed safe value upon bus breakdown or module fault, protecting field actuators and production equipment from abnormal action.
Full Galvanic Isolation: Complete isolation between field signal side and internal mainboard circuit, anti-surge & anti-electromagnetic interference for harsh industrial workshop environment.

As core field remote I/O spare of ABB AC800F DCS system,LIMELITE 2000 mainly resolves common breakdown failures: intermittent field signal loss, bus offline disconnection between field site and DCS cabinet, channel burnout leading no input/output, abnormal output drift caused by original module PCB aging and isolation component damage. Fully consistent with OEM dimension, bus protocol and terminal wiring definition, direct plug-and-play replacement without DCS program modification or field rewiring, greatly shorten production halt maintenance duration. Two supply modes available: original factory new with ABB official datasheet; refurbished version after component screening, full-bus communication test +72h continuous rack aging load inspection, both covered unified 12-month global warranty for factory regular spare inventory and urgent emergency rush order.
