ABB TB521-ETH Terminal Base High Performance Ethernet Connection for Industrial Automation
The ABB TB521-ETH Terminal Base is designed for industrial automation with Ethernet connectivity. Key specs include support for Modbus TCP/IP, up to 32 digital inputs/outputs, and a wide operating temperature range of -25°C to +70°C. It's commonly used in process control and factory automation systems. Compared to the ABB CI860, the TB521-ETH offers more I/O points but lacks the CI860's advanced communication options. It's a robust choice for applications requiring Ethernet integration and high I/O capacity.
