Chapter 2: Installation and Wiring ! Attention 2-3 EXPLOSION HAZARD Substitution of components may impair suitability for Class I, Division 2. Do not replace components or disconnect equipment unless power has been switched off or the area is known to be nonhazardous. Do not connect or disconnect components unless power has been switched off or the area is known to be non-hazardous. This product must be installed in an enclosure. All wiring must comply with N.E.C. article 501-4(b). 2.3.
2-4 MicroLogix™ 1200 Analog Combo Module (4Ch IN / 4Ch Out) Section 2.4 Mounting ! Attention Do not remove protective debris strip until after the module and all other equipment near the module is mounted and wiring is complete. Once wiring is complete and the module is free of debris, carefully remove protective debris strip. Failure to remove strip before operating can cause overheating. 2.4.1 Minimum Spacing Maintain spacing from enclosure walls, wireways, adjacent equipment, etc. Allow 50.
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 Analog Combo Module (4Ch IN / 4Ch Out) 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 2-7 wires specified by the thermocouple manufacturer. Using the incorrect type of thermocouple extension wire or not following the correct polarity will cause invalid readings. The module does not provide loop power for analog inputs. Use a power supply that matches the input transmitter specifications. Outputs Load resistance for a voltage output channel must be equal to or greater than 1K Ω.
2-8 MicroLogix™ 1200 Analog Combo Module (4Ch IN / 4Ch Out) To limit the pickup of electrical noise, keep thermocouple and millivolt signal wires as far as possible from power and load lines. If noise persists for a device, try grounding the opposite end of the cable shield or ground both ends of the shield. 2.6.1 Wiring Diagram Refer to the following wiring diagrams for field wiring connections. Figure 2-5 (Wiring Diagram) Voltage/TC Input Path 2.6.
Chapter 2: Installation and Wiring ! Attention 2-9 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. You can use the stripped end of the wire or a spade lug.

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).
