MicroLogix™ 1762-IA8 120V ac Input 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(1)) and to circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).(3) Prevent Electrostatic Discharge ! ATTENTION: Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins.
MicroLogix™ 1762-IA8 120V ac Input Module 5 Mounting ! ATTENTION: Do not remove 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 strip before operating can cause overheating.
MicroLogix™ 1762-IA8 120V ac Input Module DIN Rail Mounting The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15). 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 will momentarily open and lock into place. Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for vibration or shock environments.
MicroLogix™ 1762-IA8 120V ac Input Module 7 System Assembly The expansion I/O module is attached to the controller or another I/O module by means of a flat ribbon cable after mounting as shown below. Note: Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable. ATTENTION: 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.
MicroLogix™ 1762-IA8 120V ac Input Module Input Wiring Basic wiring(1) of input devices to the 1762-IA8 is shown below. L1 IN 0 IN 1 IN 2 IN 3 100/120V ac IN 4 IN 5 IN 6 IN 7 L2 AC COM AC COM Commons are connected internally. 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. ! (1) ATTENTION: Be careful when stripping wires.
MicroLogix™ 1762-IA8 120V ac Input Module 9 Note: Finger-safe cover not shown. Wiring the Finger-Safe Terminal Block When wiring the terminal block, keep the finger-safe cover in place. 1. Route the wire under the terminal pressure plate. You can use the stripped end of the wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug. 2. Tighten the terminal screw making sure the pressure plate secures the wire. Recommended torque when tightening terminal screws is 0.904 Nm (8 in-lbs).
MicroLogix™ 1762-IA8 120V ac Input Module I/O Memory Mapping Input Data File For each input module, the input data file contains the current state of the field input points. Bit positions 0 through 7 correspond to input terminals 0 through 7.
