Allen bradley 1756 cp3 vs 1747 cp3

The 1747-CP3 and 1756-CP3 cables are both used for programming and connecting to Allen-Bradley SLC 5/03, 5/04, and 5/05 series PLCs, as well as MicroLogix 1400 PLCs. Here are the key details and differences between the two cables:

1747-CP3 Cable

Usage: Primarily designed for SLC 5/03, 5/04, and 5/05 PLCs.
Material: Composed of copper, rubber, and steel.
Design: Standard serial cable with a typical straight-end connector.
Compatibility: Fully compatible with the mentioned SLC series PLCs.

1756-CP3 Cable

Usage: Designed for SLC 5/03, 5/04, and 5/05 PLCs, and also usable with the ControlLogix family controllers.
Material: Similar composition to the 1747-CP3 (copper, rubber, and steel).
Design: Features a lower-profile right-angle end, which can be beneficial in tight spaces or for reducing stress on the connection point.
Compatibility: Interchangeable with the 1747-CP3 for SLC series PLCs and also compatible with ControlLogix family controllers.

Both cables serve the same primary function of connecting and programming the SLC 5/03, 5/04, and 5/05 PLCs.
The 1756-CP3’s right-angle design offers an advantage in certain physical setups.
The materials used in both cables ensure durability and reliable connectivity.
For users needing to connect to and program these Allen-Bradley PLCs, either cable can be used, with the choice largely depending on physical space constraints and personal preference for connector design.
