The Allen-Bradley 1785-L30B controller is a versatile member of the PLC5 family, designed to manage up to 1024 discrete or analog I/O devices, with a complementary capacity for an additional 1024 inputs and outputs. Equipped with 32K words of user memory and two DH+/Remote I/O combo ports configurable for either adapter or scanner functions, it supports robust industrial communication via RS-232, RS-423, and RS-422A through its serial port. The 1785-L30B facilitates remote I/O architectures, connecting to a maximum of 28 remote I/O racks, and its integrated battery ensures data retention, even during power outages, with a BATT indicator LED providing charge status. A three-position key-switch enables seamless mode transitions between Run, PROG, and REM, allowing for efficient program execution and configuration versatility.
