Product Detail

Genuine FANUC A20B-8201-0170/03A Dual-Channel DeviceNet Communication Card

Integrate your automated workcells seamlessly into your plantwide industrial network with this authentic FANUC A20B-8201-0170/03A DeviceNet Board. As a specialized communication coprocessor board, this dual-channel interface card slots directly into your controller network backplane, allowing the primary CPU to transfer high-density I/O maps, alarm bits, and sequence instructions to host PLCs or peripheral field components with zero communication dropouts.

Why Source Refurbished FANUC Fieldbus Boards From Us?

Rigorous Network Loopback Testing: Fieldbus communication boards must operate with zero packet loss. Every A20B-8201-0170/03A board undergoes explicit data-transmission loop tests on functional FANUC network nodes. We closely inspect baud-rate synchronization, node address allocations, and channel isolation to guarantee standard, field-ready communication linkage.
Dual-Channel High-Efficiency Routing: Built with two independent processing paths, this board enables you to manage an master-control network loop on one channel while leaving the second channel open for local tool-end device tracking, saving slots in your cabinet rack.
Avoid Production Stoppages Economically: Intermittent network board dropouts can freeze an entire production line, triggering costly downtime flags. Our certified pre-owned units offer an immediate, highly affordable alternative to expensive OEM retail prices and long shipping lead times.
Industrial Noise Immunity: Engineered with heavy-duty physical layer optocouplers and electrical isolation barriers, this interface card protects delicate central logics against factory ground loops and EM interferences.
