MOUNTING THE MODULE
This module can be mounted on the standard din rail that
is available in most control panels.
• Find an open area of the din rail (5/8 inch minimum,
for the width of the module), and preferably as far
away from any inductive loads (relays, contactors,
etc.) as possible.
• Module orientation is not critical, however, try to
mount it so that all wiring connections can be made
neatly, and according to any applicable local codes.
• Catch one end of the DIN rail latch (at the bottom of
the module, under one edge of the DIN rail, then snap
the other latch onto the opposite side of the DIN rail,
as shown below:

WIRING THE MODULE
There are twelve total wire terminal points on this mod-
ule. Refer to the following table for the pin-out:

• Locate a suitable source for the +24 volt DC
power. Using a minimum of 18 AWG stranded
wire, connect the MINUS wire to terminal # 7.
Connect the PLUS wire to terminal # 8.
• All remaining connections will be based upon
the particular protocols that you have decided
to use. Simply match the SIGNAL NAME from the
source device to match the SIGANAL NAME of
the module. All external communications wiring
must conform with the Frick

ment publication.
