Chapter 1: Module Overview 1-3 Section 1.5 Hardware Features Channels are wired as differential inputs with the exception of RTD and resistance type inputs. One cold junction compensation (CJC) sensor comes installed on the terminal block to enable accurate readings when using thermocouple input types. The CJC sensor compensates for offset voltages introduced into the input signal as a result of the coldjunction where the thermocouple wires come into contact with the terminal block.
1-4 MicroLogix™ 1200 IO Universal Input Module Section 1.6 System Overview The module communicates to the controller through the bus interface. The module also receives 5 and 24V dc power through the bus interface. Note: An external power supply is required for all 2-wire transmitters. 1.6.1 Module Power-up At power-up, the module performs a check of its internal circuits, memory, and basic functions. During this time, the module status LED remains off.

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 IO Universal Input Module 2.3.3 Remove Power ! Attention Remove power before removing or inserting this module. When you remove or insert a module with power applied, an electrical arc may occur.
Chapter 2: Installation and Wiring 2-5 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. Debris that falls into the module could cause damage when power is applied to the module. 2.4.2 DIN Rail Mounting The module can be mounted using the following DIN rails: 35 x 7.5 mm (EN 50 022 - 35 x 7.
2-6 MicroLogix™ 1200 IO Universal Input Module 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.
Chapter 2: Installation and Wiring ! Attention 2-7 EXPLOSION HAZARD In Class I, Division 2 applications, the bus connector must be fully seated and the bus connector cover must be snapped in place. In Class I, Division 2 applications, all modules must be mounted in direct contact with each other as shown on page 25. If DIN rail mounting is used, an end stop must be installed ahead of the controller and after the last 1762 I/O module. Section 2.
2-8 MicroLogix™ 1200 IO Universal Input Module ! Attention UTILISER DES FILS D’ALIMENTATION QUI CONVIENNENT A UNE TEMPERATURE DE 20°C AU-DESSUS DE LA TEMPERATURE AMBIANTE 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.

2-10 MicroLogix™ 1200 IO Universal Input Module 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. The terminals will accept a 6.35 mm (0.25 in.) spade lug. See Figure 2-6. 3) Tighten the terminal screw making sure the pressure plate secures the wire. Recommended torque when tightening terminal screws is 0.

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).
