MicroLogix 1762-IF4 Analog Input 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-IF4 Analog Input 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-IF4 Analog Input 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 (1.59) 1762 I/O MicroLogix 1100/1200/1400 1762 I/O 100.
MicroLogix 1762-IF4 Analog Input 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-IF4 Analog Input 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 page 17). You can access the switch through the ventilation slots on the top of the module. The factory default setting for all switches is Current. Switch positions are shown below.
MicroLogix 1762-IF4 Analog Input Module 13 Basic Input Wiring to the 1762-IF4 Module Differential Sensor Transmitter Types IN 0 (+) Analog Sensor IN 0 (-) IN 1 (+) IN 1 (-) IN 2 (+) IN 2 (-) IN 3 (+) IN 3 (-) COM COM TIP Grounding the cable shield at the module end only usually provides sufficient noise immunity. 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-IF4 Analog Input Module 15 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 (0.25 in.
MicroLogix 1762-IF4 Analog Input Module Labeling the Terminals 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. 1762 Expansion I/O Addressing The addressing scheme for 1762 Expansion I/O is represented in the following figure. Data file Slot number(1) Word I1:x.0/0 Bit (0...15) Bit delimiter Input Word delimiter Slot delimiter (1) I/O located on the controller (embedded I/O) is slot 0.
MicroLogix 1762-IF4 Analog Input Module 17 The bits are defined as follows: • Sx = General status bits for channels 0…3. This bit is set when an error (over- or under-range) exists for that channel, or there is a general module hardware error. • Ox = Over-range flag bits for channels 0…3. These bits are set when the input signal is above the user-specified range. The module continues to convert data to the maximum full range value during an over-range condition.
MicroLogix 1762-IF4 Analog Input Module Data Format (Bits 14 …12) These bits indicate the format of the data as shown in the following table. Other combinations of these bits are not supported and result in an error.
