The AB 1785-L30B provides 32K words of user memory for a modular PLC installation. Two configurable network channels support DH+ or Remote I/O, alongside a serial channel for compatible communication arrangements. This processor is relevant when maintaining equipment already configured for its chassis and addressing system. Before selecting a replacement, check the original program size, channel settings, rack addresses and processor revision. The quoted scope should identify the processor, battery and any required cables separately from the chassis and I/O modules.
