The XFL521B, 522B, 523B, and 524B modules are LonMark® Association-compliant digital and analog I/O modules, which can be installed at strategic locations within a building. These modules convert sensor readings and provide output signals used for operating actuators via LonWorks® standard network variables (SNVTs). Each Distributed I/O module plugs into a base terminal block allowing communication with controllers via the built-in Echelon® LonWorks bus interface. The terminal block provides spring clamp terminals for easy connection of field cables from the various sensors and actuators.
