MicroLogix 1762-OB32T Solid State 24V DC Source Output 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.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module 9 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: 1762 I/O 1762 I/O Side MicroLogix 1100/1200/1400 1762 I/O Top Side Bottom 44913 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).
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module Panel Mounting Use the dimensional template shown below to mount the module. The preferred mounting method is to use two M4 (#8) panhead screws per module. M3.5 (#6) panhead screws may also be used, but a washer may be needed to ensure a good mechanical contact. Mounting screws are required on every module. For more than 2 I/O modules: measure (number of modules - 1) x 40 mm (1.59 in.) 95 (3.74) 40.4 (1.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module 11 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 prior to connecting any devices. Use AWG #14 wire. For AC-powered controllers, this connection must be made for safety purposes.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module Output Wiring Basic wiring of the 1762-OB32T is shown below.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module 13 Wiring Options for the I/O Module Included with your 32-point output module is a keyed 40-pin female connector and crimp type pins. These components allow you to wire I/O devices to the module using a 40-conductor cable or individual wires. Refer to Assemble the Wire Contacts on page 15 for more information on connector/pin assembly instructions.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module Labeling for the 1492 Interface Module Several different stick-on label sets are provided on a single card with 1492 Interface Modules. Each label set is identified with an I/O module catalog number and words upper and lower to identify which terminal strip the label should be affixed to. The following table identifies the 1762-OB32T 32-point labels and their location on the interface module.
MicroLogix 1762-OB32T Solid State 24V DC Source Output Module 15 Assemble the Wire Contacts 1. Strip the wire insulation to expose 4 mm (5/32 in.) of wire. Crimp pins can accept 22...26 AWG wire. ATTENTION Be careful when stripping wires. Wire fragments that fall into the module could cause damage. Once wiring is complete, be sure the module is free of all metal fragments before removing the protective debris strip. Failure to remove the strip before operating can cause overheating. 2.
