The 1768-L43 CompactLogix controller handles medium-sized industrial tasks. This module controls machine processes efficiently. It provides Logix automation platform capabilities. The design is compact and cost-effective for users.
This model supports motion control applications. The 1768-L43 also works alongside safety controllers. It features a fully isolated RS232 port. This port supports a max speed of 38.4 Kbps.
Product Procurement & Buyer Guide
Procurement managers need a precise controller for their systems. The 1768-L43 solves key integration pain points.
It uses 2MB of integrated memory for program execution. You can add a 1784-CF128 CompactFlash for non-volatile storage. This flash memory prevents accidental program deletion.
The controller supports up to sixteen 1769 I/O modules. It manages two remote I/O banks for expansion. Each bank uses a power supply distance rating of four.

This module consumes a maximum of 31.1 Watts of power. It dissipates only 6.3 Watts of heat energy. The backplane current is 1.3 Amps at 24 Volts.
Engineers value the front panel key control switch. This switch manually changes the operating mode. The controller fits in an open style enclosure.
It has a T4 temperature code rating. This rating allows operation up to 135 degrees Celsius. The unit weighs 11.9 ounces for easy handling.
Step-by-Step User & Installation Guide
Installation requires a power supply and end cap. You also need a serial cable and mounting screws.

First, mount the controller on a DIN rail. Alternatively, use a panel with M4 screws. The dimensions are 5.18 x 2.65 x 4.80 inches.
Next, connect the recommended 1747-CP3 programming cable. This cable has a right-angle connector for the controller. The other end connects to a serial port.
Then, wire the power supply within the distance rating. The controller needs 24 Volts for operation. Ensure the power is off before connecting any cables.
Finally, use the status indicators to check operation. Look for PWR, RUN, and OK lights. The module operates from 0 to 60 degrees Celsius.
