The 1785-L46C15 PLC-5/46C is an advanced programmable controller designed for managing complex industrial processes, equipped with a 48,000 Word SRAM and seamlessly integrating into a 1771 I/O Chassis. It features a powerful 48K processor capable of handling up to 32K words per data-table file and supports a maximum I/O capacity of 2048, offering efficient control with its dual front 3-pin DH+ or remote I/O communication ports, alongside a coprocessor port. The controller includes a robust, base-configured ControlNet port with a 5M bit/s speed, supporting up to 99 nodes per link, and can operate at a thermal dissipation of 59 BTU/hour while maintaining stability across a wide range of temperatures and environmental conditions, all housed in an open-style enclosure.
