What is the Honeywell XFL821A?

Pluggable LonWorks® bus I/O modules consist of a terminal socket and a removable electronic module, allowing the socket to be mounted and wired before installation. They have a dark gray housing and communicate via the LonWorks bus. These electronic modules can be swapped out without disrupting power and bus connections. Simply unplug the “old” and insert the “new” module. The firmware of pluggable I/O modules is automatically updated by the controller, and the controller automatically configures them as needed by the application. Features & Benefits:

Plug-and-play functionality for easy maintenance

Separate installation of terminal sockets and electronic modules lowers risk of damage and theft in the construction phase

Fast wiring with state-of-the-art push-in terminals (screw-type terminals also available) and bridge connectors

Wide range of sensors supported

Binary input LEDs of the pluggable I/O modules can be configured for status display (off/yellow) or alarm display (green/red) per channel

Configurable safety position for outputs in case of loss of communication with the controller

Maximum wiring flexibility due to optional accessories like auxiliary terminals and cross connectors

Can be mounted in small installation housings

Flexible mix of pluggable I/O modules covering all your application requirementsCertifications:
