ATTENTION
Remove power before removing or installing this module. When you remove or install a module with power applied, an electric arc may occur. An electric arc can cause personal injury or property damage by:
- Sending an erroneous signal to your system’s field devices, causing unintended machine motion
- Causing an explosion in a hazardous environment
- Causing permanent damage to the module’s circuitry. Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.
- Do not remove the protective debris strip until after the module and all other equipment near the module is mounted and wiring is complete. Once wiring is complete and the module is free of debris, carefully remove protective debris strip. Failure to remove the strip before operating can cause overheating.
- During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, and so on) is kept from falling into the module. Debris that falls into the module could cause damage when power is applied to the module.

Mount the Module
General Considerations
Most applications require installation in an industrial enclosure to reduce the effects of electrical interference and environmental exposure. Locate your controller as far as possible from power lines, load lines, and other sources of electrical noise such as hard-contact switches, relays, and AC motor drives. For more information on proper grounding guidelines, see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1.
ATTENTION: This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the power supply’s mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. See the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for additional information.
Mounting Dimensions
Dimensions do not include the mounting feet and DIN rail latches.
Module Spacing
Maintain spacing from objects such as enclosure walls, wireways, and adjacent equipment. Allow 50.8 mm (2 in.) of space on all sides for adequate ventilation, as shown in Figure 2.
IMPORTANT MicroLogix 1200 expansion I/O can be mounted horizontally only.
DIN Rail Mounting
Use one of the following DIN rails to mount the module:
- 35 x 7.5 mm (EN 50 022 – 35 x 7.5)
- 35 x 15 mm (EN 50 022 – 35 x 15)
For environments with greater vibration and shock concerns, use the Panel Mounting method instead of DIN rail mounting.
Before mounting the module on a DIN rail, close the DIN rail latch.
- Press the DIN rail mounting area of the module against the DIN rail. The latch opens momentarily and locks into place.
- Use DIN rail end anchors (Allen-Bradley® part number 1492-EAJ35 or 1492-EAHJ35) for vibration or shock environments.
Panel Mounting
Use the dimensional template shown in Figure 3 to mount the module. The preferred mounting method is to use two M4 or #8 pan head screws per module. You can also use M3.5 or #6 pan head screws, but you may need a washer to achieve a good ground current. Mounting screws are required on every module.
System Assembly
The expansion I/O module is attached to the controller or another I/O module with a flat ribbon cable after mounting as shown in Figure 4.
Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable.
Field Wiring Connections
Grounding the Module
In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw of the controller to the ground bus before you connect any devices. Use 2.5 mm2 (14 AWG) wire. For AC-powered controllers, this connection must be made for safety purposes.
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. See the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1 for additional information.
WARNING: Explosion Hazard
- In Class I Division 2 applications, the bus connector must be fully seated and the bus connector cover must be snapped in place.
- In Class I Division 2 applications, all modules must be mounted in direct contact with each other as shown on page 6. If DIN rail mounting is used, an end stop must be installed ahead of the controller and after the last MicroLogix 1200 expansion I/O module.
- When used in a Class I Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with a proper wiring method that complies with the governing electrical codes.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), all connected I/O must be powered from a source compliant with the Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
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. Verify that the power is removed or the area is nonhazardous before proceeding.
Wire the Module
Basic wiring(a) of the 16-point DC input module is shown in Figure 5.
Simplified Input Circuit Diagram
A write-on label is provided with the module. Mark the identification of each terminal with permanent ink, and slide the label back into the door.
ATTENTION: Sinking/Sourcing Inputs
Sourcing/Sinking describes the current flow between the I/O module and the field device. Sourcing I/O circuits supply (source) current to sinking field devices. Sinking I/O circuits are driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of the field power supply are sinking field devices. Field devices connected to the positive side (+V) of the field supply are sourcing field devices.
Wire the Fingersafe Terminal Block
When wiring the terminal block, keep the fingersafe cover in place.
- Route the wire under the terminal pressure plate. You can use the stripped end of the wire or a spade lug. The terminals accept a 6.35 mm (0.25 in.) spade lug.
- Tighten the terminal screw and make sure that the pressure plate secures the wire. Recommended torque for terminal screws is 0.90 N•m (8 lb•in).
If you must remove the fingersafe cover, insert a screwdriver into one of the square wiring holes and gently pry the cover off. If you wire the terminal block with the fingersafe cover removed, you cannot put it back on the terminal block because the wires are in the way.
ATTENTION: Be careful when stripping wires. Wire fragments that fall into a module could cause damage when power is applied. Once wiring is complete, verify that the module is free of all metal fragments.
