MicroLogix 1762-OB8 Solid-State 24V DC Source 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(1)) and to circuits not exceeding Over Voltage Category II(2) (IEC 60664-1).
MicroLogix 1762-OB8 Solid-State 24V DC Source Output Module 5 Mounting 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. Minimum Spacing MicroLogix 1200 1762 I/O Side 1762 I/O Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.
MicroLogix 1762-OB8 Solid-State 24V DC Source Output 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.
MicroLogix 1762-OB8 Solid-State 24V DC Source Output 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. TIP ATTENTION Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable. 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-OB8 Solid-State 24V DC Source Output Module Field Wiring Connections Grounding the Module This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional information. Output Wiring Basic wiring of the 1762-OB8 is shown below.
MicroLogix 1762-OB8 Solid-State 24V DC Source Output Module TIP 9 Finger-safe cover not shown for clarity. 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.
