FLEX I/O 5V DC TTL Digital Input and Output Modules
7
Publication 1794-IN119C-EN-P - August 2018
The module mounts on a 1794 terminal base.
1. Rotate the keyswitch (3) on the terminal base (4) clockwise to position 1 as
required for this type of module.
2. Make sure the FlexBus connector (1) is pushed all the way to the left to connect
with the neighboring terminal base/adapter.
You cannot install the module
unless the connector is fully extended
.
3. Make sure the pins on the bottom of the module are straight so they will align
properly with the connector in the terminal base.
4. Position the module (7) with its alignment bar (6) aligned with the groove (5) on
the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The module
is seated when the latching mechanism (2) is locked into the module.
Connect Wiring for Your Module
(using a 1794-TB3 or 1794-TB3S Terminal Base)
1. Connect individual input or output wiring to numbered terminals on the 0-15
row (A) as indicated in the Wiring Connections for 1794-IG16 and 1794-OG16
table.
2. Connect the associated input and output devices as indicated in the wiring
diagrams.
3. CV DC power to terminal 34 on the 34-51 row (C).
ATTENTION:
Do not remove or replace a Terminal Base unit when power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
ATTENTION:
During mounting of all devices, be sure that all debris (metal
chips, wire strands, etc.) is kept from falling into the module. Debris that falls
into the module could cause damage on power up.
WARNING:
When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.
