PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1756-L62 is a ControlLogix Processor Module. It features 4 MB of integrated user memory and 478 KB of I/O memory. The module handles up to 128,000 total digital I/O points and 4,000 analog I/O points. It mounts directly into 1756 chassis including 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17.
This controller supports up to 32 tasks with 100 programs per task. An onboard RS-232 serial port provides ASCII, DF1, DH-485, and Modbus communication options. Optional nonvolatile memory expansion uses the 1784-CF128 CompactFlash card. The processor draws 1.2 A at 5.1V DC and 14 mA at 24V DC backplane power.
