BL20 Economy gateways for EtherNet/IP and Modbus TCP/IP provide a flexible, in-cabinet system for distributed I/O. These economical gateways accommodate up to 32 I/O modules, resulting in a system that may contain up to 512 digital I/O points or 128 analog I/O points, as well as a combination of digital and analog points, on one gateway. They’re available with an integrated power supply, eliminating the need for an added power module to feed the I/O bus.
