Micro800

The Allen-Bradley Micro800 is a family of compact, fixed-architecture programmable controllers under Bulletin 2080, spanning four controller classes — Micro810, Micro820, Micro830, Micro850, and Micro870 — suited for standalone machine control and simple automation tasks. Catalog numbers follow a structured format: the base-unit designator (e.g., -LC20 for Micro820 without Ethernet, -L20E for Micro820 with embedded Ethernet and USB-C, -L50E for Micro850 with Ethernet) is followed by the I/O point count (10–48 points), input voltage class (A=110V AC, Q=24V AC/DC, D=12V DC), output type (W=relay, B=24V DC source, V=24V DC sink), and control-power class (B=24V DC). Optional suffixes include K for conformal coating and N for DNP3 support (Micro870 only). The family supports plug-in expansion modules such as the 2080-RTD2 (4-point RTD input), 2080-OW4I (4-point relay output), and 2080-MOT-HSC (high-speed counter with line driver). Full specifications and ordering details are available in the Micro800 Technical Data (2080-TD001).
