Installed in a 1771 chassis, it utilizes backplane power from compatible power supplies including the 1771-P4S, P6S, P4S1, and P6S1. With a backplane current draw of 3.3 A and power dissipation of 17.3 W, the 1785-L40E provides dependable operation within industrial environments. This PLC features 48K words of user memory, stored in battery-backed static RAM using the 1770-XYC battery. Optional EEPROM memory modules (1785-ME16\/32\/64\/M100) provide non-volatile program retention. The 1785-L40E supports up to 2048 total I\/O, or 2048 input + 2048 output in complementary mode, and can control up to 61 total I\/O chassis across local and remote links.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePLC-5\/40E processor with EtherNet\/IP networking\u003c\/li\u003e\n\u003cli\u003e48K word battery-backed SRAM user memory\u003c\/li\u003e\n\u003cli\u003eSupports up to 2048 I\/O (or 2048 in + 2048 out complementary)\u003c\/li\u003e\n\u003cli\u003eTwo DH+\/Remote I\/O ports (scanner or adapter)\u003c\/li\u003e\n\u003cli\u003eOne serial port (RS-232\/422A\/423)\u003c\/li\u003e\n\u003cli\u003eOne 10\/100 Mbps Ethernet port\u003c\/li\u003e\n\u003cli\u003eSupports up to 61 total I\/O chassis\u003c\/li\u003e\n\u003cli\u003eOptional EEPROM backup memory\u003c\/li\u003e\n\u003cli\u003eSupports ladder, SFC, and structured-text programming\u003c\/li\u003e\n\u003cli\u003eCompatible with all 1771 discrete, analog, and intelligent I\/O modules\u003c\/li\u003e\n\u003cli\u003eEtherNet\/IP-enabled PLC-5\/40E controller with 48K memory, multiple network ports, and large-scale I\/O capacity for advanced automation systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe controller supports IEC 61131-3 programming languages including Ladder Logic, Structured Text, and Sequential Function Chart (SFC).
