2080-LC50-24QBB — Micro850 24-Point Compact Controller, High-Speed I/O, Ethernet

The 2080-LC50-24QBB is a 24-point expandable controller from the Micro850 family, combining 14 inputs (8 high-speed plus 6 standard, 24V AC/DC) with 10 sourcing DC outputs (2 high-speed plus 8 standard). It includes a USB programming port, a non-isolated RS-232/485 serial port, and an embedded Ethernet port, and supports up to 4 expansion I/O modules for a combined total of up to 132 I/O points.

High-Speed I/O for Counting and Motion-Adjacent Tasks

The dedicated high-speed input and output channels are what separate this controller from a purely general-purpose unit — input channels 0–7 and output channels 0–1 are specifically built for fast, precise counting and motion-adjacent applications where standard-speed I/O would miss pulses or introduce timing error. Four embedded high-speed counter channels extend this further, covering encoder feedback, flow pulse counting, or indexing applications without requiring a separate dedicated counter module.

Expansion to up to 132 total I/O points across four expansion modules gives this controller meaningful headroom beyond its onboard 24 points — a machine that starts with modest I/O needs can add digital, analog, or specialty modules as the application grows, without a controller swap. The embedded Ethernet port covers programming, basic network communication, and DF1 protocol modes for legacy device integration, rounding out a flexible communication set for a controller in this size class.

FAQ

Q: Can the high-speed inputs also be used for standard discrete sensing if high-speed capability isn't needed?

Yes. The high-speed channels function as standard digital inputs as well — there's no requirement to use their high-speed capability if the connected sensor or device doesn't need it.

Q: How many expansion modules can be added, and what's the resulting total I/O count?

Up to 4 expansion I/O modules can be added, bringing the combined total — onboard plus expansion — to as many as 132 I/O points depending on the specific modules selected.

Q: What are the 4 high-speed counter channels typically used for?

Common applications include encoder position feedback, flow meter pulse counting, and part-counting or indexing tasks where standard scan-based logic would be too slow to reliably capture fast pulse trains.

Q: Does the embedded Ethernet port support DF1 protocol in addition to EtherNet/IP?

Yes. This controller's Ethernet port supports additional DF1 protocol modes alongside standard EtherNet/IP communication, useful for integration with legacy devices that rely on DF1 over a network connection.
