CompactBlock LDX I/O

Our Bulletin 1790D CompactBlock™ LDX I/O modules are a cost-effective distributed I/O solution for light industrial environments where high-protection specifications and advanced performance features are not required. Base blocks include I/O points and a built-in DeviceNet™ network adapter. Digital I/O expansion blocks provide the flexibility to add I/O points to your CompactBlock LDX I/O system.

1790 CompactBlock LDX I/O |  Overview

Overview

  • Includes compact package for easy installation in confined areas, including wireways and operator terminals
  • Offers base blocks that provide 4…32 I/O points
  • Includes built-in DeviceNet™ network connectivity
  • Allows addition of expansion blocks to a base block for up to 80 points per node
  • Includes universal sink/source inputs which reduce the number of components to stock and provide flexibility of input types
  • Includes node address switches and autobaud rate detection which simplifies network commissioning
  • Offers fixed screw terminals for convenient disconnection
