1790D 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.
