Allen-Bradley SLC 500 Modular Processors Features Four Central Processing Units Variety of 1747 I/O Modules Four Power Supplies Variety of Communication Options Description The Rockwell/Allen-Bradley SLC 500 Modular Processors is a family of small programmable controllers built around 2 hardware options: a fixed controller or a modular controller. The fixed controller provides the following: power supply, inputs and outputs, and processor all in one unit; and a 2-slot expansion chassis for increased flexibility. The modular controller offers additional flexibility in system configuration, more processing power, and I/O capacity; thus allowing the creation of a controller system specifically designed for your application. These controllers communicate across an embedded DH-485 network which allows program support and monitoring.
