FLEX I/O AC Digital Input Modules Installation Instructions
Special Conditions for Safe Use
ATTENTION:
• This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can corrode, oxidize, or are poor conductors, can result in improper or
intermittent grounding. Secure DIN rail to the mounting surface approximately every 200 mm (7.8 in.) and use end-anchors appropriately. Be sure to
ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for more information.
• Do not remove or replace an adapter while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.
• Do not remove or replace a terminal base while power is applied. Interruption of the backplane cab result in unintentional operation or
machine motion.
• If this equipment is used in a manner that is not specified by the manufacturer, the protection that is provided by the equipment may be impaired.
WARNING: If you connect or disconnect wiring while the field-side power is on, an electric arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
WARNING:
• When you insert or remove the module while backplane power is on, an electric arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding. Repeated electric arcing causes excessive wear to contacts on both
the module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.
• If you insert or remove the module while backplane power is on, an electric arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Electrical Safety Considerations
ATTENTION:
• This equipment is certified for use only within the surrounding air temperature range of -20…+55 °C (-4…+131 °F). The equipment must not be used
outside of this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any cleaning agents.

FLEX I/O AC Digital Input Modules Installation Instructions
Install Your Module
The FLEX™ I/O AC digital input module mounts on a 1794 terminal base.
ATTENTION: During mounting of all devices, be sure that all debris (metal chips, wire strands, and so on) are kept from falling into the module. Debris
that falls into the module could cause damage on power-up.
1.
2.
3.
Rotate the keyswitch (3) on the terminal base (4) clockwise to position 8 as required for this type of module.
Make sure that 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.
Make sure that the pins on the bottom of the module are straight so they align properly with the connector in the terminal base.
WARNING: If you insert or remove the module while backplane power is on, an electric arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
4.
5.
Position the module (4) with its alignment bar (5) aligned with the groove (6) on the terminal base.
Press firmly and evenly to seat the module in the terminal base. The module is seated when the latching mechanism (2) is locked into the the module.

120V AC L1
Power terminals C-34 to C-51 (C-34 and C-51 on 1794-TBN) are internally connected together. Connect 120V AC L1 to C-34.
120V AC L2
Common terminals B-16 to B-33 (B-16 and B-33 for 1794-TBN) are internally connected together. Connect 120V AC common L2 to terminal B-16.
(1)
When using the 1794-TBN, you must use an external terminal strip to connect the 120V AC power connections.
Connect Wiring for the 1794-IA8I
1.
Connect wiring to the different terminal bases as follows:
For 1794-TB2, 1794-TB3, or 1794-TB3S – Connect individual input wiring to even-numbered terminals on the 0...15 row (A) as indicated in the Wiring Connections for 1794IA8I table.
For 1794-TBN – Connect individual input wiring to even-numbered terminals 0...14 on the 16...33 row (B) as indicated in the Wiring Connections for 1794-IA8I table.
For 1794-TB2, 1794-TB3, or 1794-TB3S – Connect the associated 120V AC common (L2) of the isolated supply to the corresponding odd-numbered terminals on the 0...15
row A for each input as indicated in the Wiring Connections for 1794-IA8I table.
For 1794-TBN – Connect the associated 120V AC common lead (L2) of the isolated supply to the corresponding odd-numbered terminal 1...15 on the 34...51 row (C) as
indicated in the Wiring Connections for 1794-IA8I table.
IMPORTANT
Individual isolated 120V AC L1 power leads must be run externally to each of the input devices.
