Description
Product Description
The 57C440A RELIANCE is an Ethernet communication module from Reliance Electric for programmable logic controllers (PLCs). It allows PLCs to communicate with other devices on an Ethernet network, such as PCs, servers, and other PLCs. This makes it possible to create distributed control systems (DCSs) and other complex automation systems.
The 57C440A RELIANCE is a newer version of the 57C440 RELIANCE and includes several improvements, such as:
- Faster communication speed: 10/100/1000 Mbps
- Support for more communication protocols: Ethernet/IP, Modbus TCP, and PROFINET
