Short Description
Description:
The Allen-Bradley 1769-L24ER-QBFC1B is a high-performance CompactLogix controller intended for applications that demand both digital and analogue signal processing in a small footprint.
It is part of the 5370 L2 series and combines a controller, digital I/O, analogue I/O, and communication ports into a single unit, thereby saving panel area, wiring complexity, and installation time.
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.
It can accommodate up to four more 1769 I/O modules, allowing for system expansion.
The controller has two EtherNet/IP ports that support Device Level Ring (DLR) for network redundancy, as well as a USB 2.0 interface for programming and diagnostics.
A 1GB SD card is supplied for data logging and backup, with capacity for up to 2GB.
The 1769-L24ER-QBFC1B uses a 24V DC power source, attaches on a DIN rail, and is rated for temperatures ranging from 0°C to 60°C.
It's ideal for machine control, process automation, and mixed-signal tasks including temperature management, flow monitoring, and sensor integration.
