CompactLogix Isolated Analog Input Module Prevent Electrostatic Discharge ATTENTION: This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation. Follow these guidelines when you handle this equipment: • • • • • • Touch a grounded object to discharge potential static. Wear an approved grounding wriststrap. Do not touch connectors or pins on component boards. Do not touch circuit components inside the equipment.
CompactLogix Isolated Analog Input Module 7 1. Disconnect power. 2. Check that the bus lever of the module to be installed is in the unlocked (fully right) position. 3. Use the upper and lower tongue-and-groove slots (1) to secure the modules together (or to a controller). 4. Move the module back along the tongue-and-groove slots until the bus connectors (2) line up with each other. 5. Push the bus lever back slightly to clear the positioning tab (3). Use your fingers or a small screwdriver. 6.
CompactLogix Isolated Analog Input Module Grounding the Module ATTENTION: This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the power supply's mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for additional information.
CompactLogix Isolated Analog Input Module 9 4. Drill and tap the mounting holes for the recommended M4 or #8 screw. 5. Place the modules back on the panel and check for proper hole alignment. 6. Attach the modules to the panel using the mounting screws. TIP If mounting more modules, mount only the last one of this group and put the others aside. This reduces remounting time during drilling and tapping of the next group. 7. Repeat steps 1… 6 for any remaining modules.
CompactLogix Isolated Analog Input Module 7. Slide the replacement module into the open slot. 8. Connect the modules together by locking (fully left) the bus levers on the replacement module and the right-side adjacent module. 9. Replace the mounting screws (or snap the module onto the DIN rail). Replacement Part Terminal block, catalog number 1769-RTBN18 (one per kit). System Wiring Guidelines ATTENTION: Use supply wires suitable for 20 °C (68 °F) above surrounding ambient.
CompactLogix Isolated Analog Input Module 11 • Voltages on Ch+, Ch-, and Ch_iRtn for a single, isolated channel of the 1769-IF4I module must not exceed the maximum overload levels detailed in the Input Specifications on page 21. ATTENTION: To comply with UL restrictions, this equipment must be powered from a source compliant with Class 2 or Limited Voltage/Current. Be careful when stripping wires. Wire fragments that fall into a module could cause damage at power up.

CompactLogix Isolated Analog Input Module 13 Labeling the Terminals A removable, write-on label is provided with the module. Remove the label from the door, mark the identification of each terminal with permanent ink, and slide the label back into the door. Your markings (ID tag) will be visible when the module door is closed.
CompactLogix Isolated Analog Input Module You can use the bare wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug. The terminal screws are non-captive. Therefore, it is possible to use a ring lug [maximum 1/4 inch o.d. with a 0.139 in. minimum i.d. (M3.5)] with the module. TIP 3. Tighten the terminal screw, making sure the pressure plate secures the wire. Recommended torque when tightening terminal screws is 0.68 N•m (6 lb•in).
CompactLogix Isolated Analog Input Module 15 The bits are defined as follows: • • • • • • SGN = Sign bit in two’s complement format Nu = Not used. Bit set to 0 Sx = General status bit for input channels 0…3 Lx = Low alarm flag bits for input channels 0…3 Hx = High alarm flag bits for input channels 0…3 Ux = Under-range flag bits for channels 0…3 When set, the input signal is under normal range or an open circuit condition exists, in the case of the 4…20 mA range.
CompactLogix Isolated Analog Input Module Configuration Data File The manipulation of the bits from this file is normally done with programming software (for example, RSLogix 5000 or RSNetWorx for DeviceNet software) during initial configuration of the system. In that case, graphical screens are provided by the programmer to simplify configuration. However, some systems, like the 1769-ADN DeviceNet adapter, also allow the bits to be altered as part of the control program, using communication rungs.
