CompactLogix 750KB DI/O AI/O Controller

Description: The Allen-Bradley 1769-L24ER-QBFC1BK is a ruggedized variant of the 1769-L24ER-QBFC1B controller from the CompactLogix 5370 L2 family. It combines a controller, digital and analogue I/O, and communication interfaces in a single compact box, making it excellent for space-constrained applications that require mixed-signal control. This model contains: 750KB of user RAM. 16 digital inputs (24 volts DC). 16 digital outputs (24V DC source). Four universal analogue inputs (for voltage, current, and thermocouple signals). Two analogue outputs. Four high-speed counter channels. The "K" suffix denotes conformal coating, which protects internal circuitry from moisture, dust, and corrosive chemicals, making it appropriate for harsh industrial applications such as food processing, chemical plants, and outdoor installations. It can accommodate up to four additional 1769 I/O modules, has dual EtherNet/IP ports with Device Level Ring (DLR) functionality for network redundancy, and contains a USB 2.0 connector for programming and diagnostics. A 1GB SD card is supplied for data logging and backup, with capacity for up to 2GB. This controller is suited for machine control, process automation, and mixed-signal applications requiring environmental robustness and compact integration.
