The Allen-Bradley 1769-L31 Programmable Automation Controller is a versatile member of the CompactLogix family, designed for small to medium-scale applications. This controller features dual RS232 communication interfaces, with channel 0 supporting DF1, DH-485, and ASCII protocols via a fully isolated port, and channel 1 supporting DF1 and DH-485 through a non-isolated port, both capable of transmitting at speeds up to 38.4 kbps. With a user memory capacity of 512 KB, expandability up to 16 local I/O modules, and compatibility with CompactFlash cards for non-volatile memory, this device ensures robust system performance. Engineered for reliability, it incorporates LED status indicators, I/O forcing capabilities for streamlined commissioning, and operates within a temperature range of 0 - 60 °C and 30g shock resistance, making it suitable for industrial environments.
