Compact 32-point Solid-state 24V dc Source Output Module Module Installation Compact 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).
Compact 32-point Solid-state 24V dc Source Output Module 5 System Assembly The module can be attached to the controller or an adjacent I/O module before or after mounting. For mounting instructions, see Panel Mounting on page 6, or DIN Rail Mounting on page 8. To work with a system that is already mounted, see Replacing a Single Module within a System on page 8. The following procedure shows you how to assemble the Compact I/O system. 3 4 2 1 6 1 5 30536-M 1. Disconnect power. 2.
Compact 32-point Solid-state 24V dc Source Output Module 7. Attach an end cap terminator (5) to the last module in the system by using the tongue-and-groove slots as before. 8. Lock the end cap bus terminator (6). IMPORTANT A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the serial communication bus. Mounting Expansion I/O ATTENTION ! During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.
Compact 32-point Solid-state 24V dc Source Output Module 7 Panel Mounting Using the Dimensional Template Host Controller Spacing for single-wide modules 35 mm (1.378 in.) Spacing for one-and-a half-wide modules 52.5 mm (2.067 in.) Refer to host controller documentation for this dimension. Note: Overall hole spacing tolerance: ±0.4 mm (0.016 in.). Locate holes every 17.5 mm (0.689 in.) to allow for a mix of single-wide and one-and-a-half-wide modules (e.g. 1769-OA16).
Compact 32-point Solid-state 24V dc Source Output Module DIN Rail Mounting The module can be mounted using these 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 latches. Press the DIN rail mounting area of the module against the DIN rail. The latches will momentarily open and lock into place.
Compact 32-point Solid-state 24V dc Source Output Module 9 Field Wiring Connections Grounding the Module This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the module’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, Allen-Bradley publication 1770-4.1, for additional information.
Compact 32-point Solid-state 24V dc Source Output Module A removable write-on label is included 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. R SLOT# MODULE TYPE L 30517-M Removing the Finger-safe Terminal Block When wiring field devices to the module, it is not necessary to remove the terminal block.
Compact 32-point Solid-state 24V dc Source Output Module 11 2. Route the wire under the terminal pressure plate. You can use the bare wire or a spade lug. The terminals will accept a 6.35 mm (0.25 in.) spade lug. TIP 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 inch minimum i.d. (M3.5)} with the module. 3. Tighten the terminal screw making sure the pressure plate secures the wire.
Compact 32-point Solid-state 24V dc Source Output Module Wire Size and Terminal Screw Torque Each terminal accepts as many as two wires with these restrictions: Wire Type Wire Size Terminal Screw Torque Retaining Screw Torque Solid Cu-90°C (194°F) #14 to #22 AWG 0.68 Nm (6 in-lbs) 0.46 Nm (4.1 in-lbs) Stranded Cu-90°C (194°F) #16 to #22 AWG 0.68 Nm (6 in-lbs) 0.46 Nm (4.
Compact 32-point Solid-state 24V dc Source Output Module 13 The output module’s input data file reflects the output data echo of the module, not necessarily the electrical state of the output terminals. It does not reflect shorted or open outputs. IMPORTANT It is important to use this input word if the controller adapter supports the Program Mode or Fault Mode function, and if it is configured to use them.
Compact 32-point Solid-state 24V dc Source Output Module Program State Word Word 1, the program state word, selects the hold last state or user-defined safe state condition for each individual output on a system transition from Run to Program.

Compact 32-point Solid-state 24V dc Source Output Module The graph below illustrates that the duration of the transient is proportional to the load current. Therefore, as the on-state load current increases, the transient pulse decreases. Power-up transients do not exceed the time duration shown below, for the amount of loading indicated, at 60°C (140°F).
