Allen-Bradley 1790L811 — CompactBlock LDX I/O Module

AB · 1790 CompactBlock · LDX I/O · In stock

The 1790L811 is a member of the Allen-Bradley Allen-Bradley CompactBlock LDX family of IP67-rated, on-machine I/O blocks. It is designed to mount directly on a machine or in a wet/washdown area, with M12 connectors and a sealed housing that lets it survive the environment a traditional cabinet-mounted factory automation block cannot. KOEED stocks 1790L811 for engineers who need to replace a failed block on an existing line without redesigning the field wiring.

The CompactBlock LDX line is the natural choice when sensors and actuators sit on the machine rather than in a control cabinet — automotive cells, packaging machinery, conveyor sections, and material handling. The 1790L811 is one of the catalog numbers that has historically been hard to keep in the distribution channel; KOEED quotes BOMs that mix it with Siemens ET 200, Mitsubishi CC-Link, and Omron DRT2 IP67 blocks in the same shipment.

Key Specifications

Series 1790 CompactBlock LDX
Part Number 1790L811
Module Type On-machine I/O block — discrete I/O

Stock Status In stock — quote within 24 hours at Moritta@KOEED.COM

Datasheet Highlights

  • Sealed IP67 housing eliminates the need for a control cabinet at the machine, reducing footprint and shortening field-wiring runs
  • M12 connector standard allows standard sensor cables to plug in directly with no custom harnesses
  • LED status indication on every port for fast diagnostics on the shop floor
  • Drop-in compatible with the existing LDX wiring harness in a typical machine retrofit
  • Designed for high-vibration, washdown and dust-loaded environments where a standard 1734 POINT I/O block would not survive

Typical Applications

  • Automotive body-in-white cells and assembly conveyors
  • Food & beverage packaging lines with daily washdown
  • Distribution-centre sortation and conveyor systems
  • Tier-1 OEM machinery builders that ship cells globally and prefer field-replaceable sealed I/O
  • Plant retrofit projects converting cabinet-mounted I/O to on-machine sealed blocks
