MicroLogix 1762-IF2OF2 Analog Input/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-IF2OF2 Analog Input/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-IF2OF2 Analog Input/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 two I/O modules: measure (number of modules - 1) x 40 mm (1.59 in.) 95 (3.74) 40.4 (1.
MicroLogix 1762-IF2OF2 Analog Input/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-IF2OF2 Analog Input/Output Module 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 Configuration Data File on page 19). You can access the switch through the ventilation slots on the top of the module. Switch 1 controls channel 0; switch 2 controls channel 1. The factory default setting for both switch 1 and switch 2 is Current.
MicroLogix 1762-IF2OF2 Analog Input/Output Module 13 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. • Use Belden 8761, or equivalent, shielded wire. • Under normal conditions, the drain wire (shield) should be connected to the metal mounting panel (earth ground).

However, for best cable shield performance, earth ground the shield at both ends, using a 0.01µF capacitor at one end to block AC power ground currents, if necessary.

MicroLogix 1762-IF2OF2 Analog Input/Output Module Wiring the Finger-Safe Terminal Block ATTENTION Be careful when stripping wires. Wire fragments that fall into a module could cause damage when power is applied. Once wiring is complete, ensure the module is free of all metal fragments. 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.
