Page 4: Installation
MicroLogix™ Analog Input/Output Module Installation 1762 I/O is suitable for use in an industrial environment when installed in accordance with these instructions. Specifically, this equipment is intended for use in clean, dry environments (Pollution degree 2 ) and to circuits not exceeding Over Voltage Category II (IEC 60664-1).
Page 5: Mounting
MicroLogix™ Analog Input/Output Module Mounting Do not remove protective debris strip until after the module and ATTENTION 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 strip before operating can cause overheating.
Page 6 DIN rail mounting area of the module against the DIN rail. The latch will momentarily open and lock into place. Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for environments with vibration or shock concerns. End Anchor...
Page 7: System Assembly
MicroLogix™ Analog Input/Output Module System Assembly The expansion I/O module is attached to the controller or another I/O module by means of a ribbon cable after mounting as shown below. Use the pull loop on the connector to disconnect modules. Do NOTE not pull on the ribbon cable.
Page 8: Field Wiring Connections
DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional information. Input Type Selection Select the input type, current or voltage, using the switch located on the module’s circuit board and the input type/range selection bits in the Configuration Data File (see page 16).
Page 9: Wiring
MicroLogix™ Analog Input/Output Module Wiring System Wiring Guidelines Consider the following when wiring your system: • The analog common (COM) is not connected to earth ground inside the module. All terminals are electrically isolated from the system. • Channels are not isolated from each other. •...
