Compact™ Solid State 24V dc Source Output Module 3 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™ Solid State 24V dc Source Output Module 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 5, or "DIN Rail Mounting" on page 7. To work with a system that is already mounted, see "Replacing a Single Module within a System" on page 7. The following procedure shows you how to assemble the Compact I/O system. 3 4 2 1 6 1 5 1. Disconnect power. 2.
Compact™ Solid State 24V dc Source Output Module 5 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.

Hole spacing tolerance: ±0.4 mm (0.016 in.). Compact I/O 132 (5.197) Host Controller For more than 2 modules: (number of modules - 1) x 35 mm (1.38 in.) Refer to host controller documentation for this dimension.
Compact™ Solid State 24V dc Source Output Module 7 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). 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™ Solid State 24V dc Source Output Module 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™ Solid State 24V dc Source Output Module 9 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. SLOT # _____ MODULE TYPE ______ Removing the Finger-Safe Terminal Block When wiring field devices to the module, it is not necessary to remove the terminal block.
Compact™ Solid State 24V dc Source Output Module 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. 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. TIP 3. Tighten the terminal screw making sure the pressure plate secures the wire. Recommended torque when tightening terminal screws is 0.
Compact™ Solid State 24V dc Source Output Module 11 I/O Memory Mapping Output Data File For each module, slot x, word 0 in the output data file contains the control program’s directed state of the discrete output points.
Compact™ Solid State 24V dc Source Output Module 1769-OB16 Configuration File The read/writable configuration data file allows the setup of the hold last state and user-defined safe state conditions. Word The manipulation of the bits from this file is normally done with programming software (e.g. RSLogix 500, RSNetworx for DeviceNet, etc.) during initial configuration of the system. In that case, graphical screens are provided via the programmer to simplify configuration. However, some systems (e.g.
Compact™ Solid State 24V dc Source Output Module 13 Fault Value Word The fault value word, word 4, is used to program the fault state value (0=Off, 1=On). Each output is individually configurable for on or off.

Compact™ Solid State 24V dc Source Output Module 17 Transistor Output Transient Pulses The maximum duration of the transient pulse occurs when minimum load is connected to the output. However, for most applications, the energy of the transient pulse is not sufficient to energize the load. A transient pulse occurs in transistor outputs when the external DC supply voltage is applied to the output common terminals (e.g. via the master control relay).
