1747-L551Products: 1747-L551

Description: 1746 SLC System  SLC 5/05 Controller – 16K Memory.

The SLC 5/05 processor provides the same functionality as the SLC 5/04 processor with standard Ethernet communications rather than DH+ communications. Ethernet communication occurs at 10 Mbps or 100 Mbps, providing a high performance network for program upload/download, online editing, and peer-to-peer messaging. Modular I/O systems can be configured with a maximum of 3 chassis (30 total slots) and from 4 I/O
points to a maximum of 4096 I/O points.
