Product Design
The MicroLogix 1200 controller and expansion I/O modules provide a modular, rackless control system designed for ease of installation and maintenance. Each MicroLogix 1200 controller includes a processor, built-in I/O, and power supply. Expansion I/O modules install to the right of the controller. Cables built into the I/O modules provide connection to the adjacent I/O module or controller. Controllers and I/O modules can be mounted either on a panel or on a DIN-rail. I/O on both controller and expansion I/O modules have finger-safe terminal blocks to meet global safety standards. The 40-I/O controllers have removable terminal blocks to facilitate ease of wiring and maintenance.
Operator Interfaces
Many Allen-Bradley operator interface products can be used with MicroLogix 1200 controllers. The PanelView 300 Micro operator interface is a small, low cost, easy-to-use operator interface that is designed for use with the MicroLogix 1200 controller.

SLC Processors
The SLC processors offer a wide range of choices in memory, I/O capacity, instruction set, and communication ports to allow you to tailor a control system to your exact application requirements. These products have a strong reliability history covering hundreds of thousands of installations in a broad range of applications.
SLC 5/01 processors let you configure modular controllers of up to 960 I/O and a 1K- or 4K-instruction memory capacity.
SLC 5/02 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs nominally and a 4K-instruction memory. By installing an optional scanner module into one of the 30 I/O module slots, you can add ControlNet I/O, DeviceNet I/O, or Universal Remote I/O to the system. They offer 19 additional instructions, including a message instruction for initiating peer-to peer communication.
SLC 5/03 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of 8K, 16K, or 32K words. In addition to the features of the SLC 5/02, they have a second built-in communication port—an RS-232-C port that can be configured for ASCII or DF1 protocol, and can be configured for connection to a 1761-NET-AIC converter to provide access to a DH-485 network. SLC 5/03 processors provide bit-instruction execution times of 0.44 ms and an overall system throughput of up to 10 times faster than competitive processors. Additional capabilities include: floating-point math, online programming and run-time editing, flash memory upgrades, built-in key-switch, and a built-in real-time clock and calendar.
SLC 5/04 and 5/05 processors let you configure modular controllers of up to 4096 inputs plus 4096 outputs and a memory of either 16K, 32K, or 64K words. They have all the features of the SLC 5/03 processors, plus a faster communication port and shorter execution times (bit-instruction execution times of 0.37ms). Instead of a DH-485 port, the SLC 5/04 has a built-in DH+ port for communication with other SLC 5/04 and PLC processors, operator interfaces, and programming terminals. Communication via the DH+ network is three times faster than DH-485 communication. SLC 5/05 processors provide a 10/100BASE-T, 10 or 100 Mbps Ethernet port.
