The DO-FA-12 and DO-FA-12-H are digital output
12 channel I/O modules.
The digital outputs support digital Form A point
types. The Form A relays are designed for direct
load applications.
Patented two-piece design
Each module can be separated from its terminal
base to allow the site to be wired prior to the
installation of the electronics. The patented locking
mechanism serves as handles for removing the
module from its base. All critical components have
a protective cover that permits convection cooling
to occur.
Function
Modular and scalable system
The modules are part of a modular system that
delivers power and communications on a common
bus. Connecting modules is a one-step process:
just slide the modules together using the built-in
connectors.

The I/O module terminals are clearly labeled and
protected by transparent covers. The input and
output terminals are at the top and bottom of each
module and are accessible for maintenance without
removing the module. The StruxureWare Building
Operation WorkStation software can generate
custom as-built labels for each module. Preperforated letter and A4 size label sheets are
available as an accessory.
Accommodates multiple row panel installations
The SmartStruxure devices use built-in connectors
for single row connectivity, side by side. If a panel
size requires multiple rows, extension cords are
available.

Hot-connect and Hot-swap
LED status indicators
The I/O module has a status indicator that denotes
the health and status of the module.
Because critical applications require 24-hour
operation, Schneider Electric designed the I/O
modules for hot-connection of terminal bases and
Each digital output channel has a dedicated status
indicator using a green LED.
hot-swapping of the modules to their bases. This
design ensures continuous power and
communication during service operations.
Auto-addressing
Hand/Off/Auto switches
The front panel of the DO-FA-12-H includes
Hand/Off/Auto (HOA) switches to provide override
control of the digital outputs.
The auto-addressing feature eliminates the need for
setting DIP switches or pressing commission
buttons. Each module automatically knows its order
in the chain and assigns itself accordingly –
significantly reducing engineering and maintenance
The position of the HOA switch is readable through
user interfaces, such as the StruxureWare Building
Operation WorkStation software, enabling more
precise monitoring and control.

Simple DIN-rail installation
Fasteners easily snap into a locked position for
panel installation. The fastener has a quick-release
feature for easy DIN-rail removal.
