Chapter 2: Installation and Wiring 2-3 2.3.2 Prevent Electrostatic Discharge ! Attention Electrostatic discharge can damage integrated circuits or semiconductors if you touch analog I/O module bus connector pins or the terminal block on the input module. Follow these guidelines when you handle the module: Touch a grounded object to discharge static potential. Wear an approved wrist-strap grounding device. Do not touch the bus connector or connector pins.
2-4 MicroLogix™ 1200 IO 8 Ch Output Module 2.4.1 Minimum Spacing Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50.8 mm (2 in.) of space on all sides for adequate ventilation, as shown: Figure 2-1 Note: 1762 expansion I/O may be mounted horizontally only. ! Attention During panel or DIN rail mounting of all devices, be sure that all debris (metal chips, wire strands, etc.) is kept from falling into the module.
Chapter 2: Installation and Wiring 2-5 Figure 2-2 Note: For environments with extreme vibration and shock concerns, use the panel mounting method described below, instead of DIN rail mounting. 2.4.3 Panel Mounting Use the dimensional template shown below to mount the module. The preferred mounting method is to use two M4 or #8 Pan Head screws per module. M3.5 or #6 Pan Head screws may also be used, but a washer may be needed to ensure a good ground contact. Mounting screws are required on every module.
2-6 MicroLogix™ 1200 IO 8 Ch Output Module Figure 2-4 Note: Use the pull loop on the connector to disconnect modules. Do not pull on the ribbon cable. EXPLOSION HAZARD In Class I, Division 2 applications, the bus connector must be fully seated and the bus connector cover must be snapped in Attention place. In Class I, Division 2 applications, all modules must be mounted in direct contact with each other as shown on page 24.

Chapter 2: Installation and Wiring 2-9 2.6.2 Wiring the Finger-Safe Terminal Block Figure 2-6 ! 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) Refer to section 2.6.1for proper field wiring connections. 2) Route the wire under the terminal pressure plate.
2-10 MicroLogix™ 1200 IO 8 Ch Output Module Figure 2-7 (Door Label) Section 2.7 Module Indicators The 1762 output module uses a single green LED to show operational status of the module. The LED will illuminate solid when the PLC is in run mode and the module properly configured. If the module is not properly configured, or if the PLC is not in run mode, the LED will blink rapidly.

Select the first empty slot and then double-click the “Other—Requires I/O Card Type ID” option, from the I/O configuration screen. 4.
Chapter 3: Configuring the 1762sc-OF8 for RSLogix 500 3-3 5.) Repeat steps 1 through 4 for additional modules. Section 3.4 Module Configuration The OF8 module is configured using a process that employs the input and output files. The following flow chart describes the configuration process.
3-4 MicroLogix™ 1200 IO 8 Ch Output Module 3.4.1 Output Data File (Command Mode) The output data file is used to configure each channel for the OF8 as well as control the output signal of each channel. Use the addressing scheme below to locate the 8 output words needed to configure the module. Figure 3-2 (Output Addressing Scheme) (1) I/O located on the controller (embedded I/O) is slot 0. I/O added to the controller (expansion I/O) begins with slot 1.
Chapter 3: Configuring the 1762sc-OF8 for RSLogix 500 3-5 2) Validate Command: If the Fixed Words are valid, the Command word will be checked. If it is not set to a valid command, an error will be reported. Initially the module only checks for the Unlock command. After the Unlock command is detected, the module must detect a transition in the Command word to trigger a new command. The available commands are listed in the table below.

Getting Technical Assistance Note that your module contains electronic components which are susceptible to damage from electrostatic discharge (ESD). An electrostatic charge can accumulate on the surface of ordinary plastic wrapping or cushioning material. In the unlikely event that the module should need to be returned to Spectrum Controls, please ensure that the unit is enclosed in approved ESD packaging (such as static-shielding / metalized bag or black conductive container).
