Details: ICDM-RX/MOD-4DB9/2RJ45-DIN


The ICDM-RX/MOD product family provides an innovative network-wide Modbus connectivity from a wide variety of Modbus masters to a wide variety of local and remote Modbus slaves. Advanced features include master-to-master communication, private serial bus connectivity, write protection, and device ID aliasing. With simplified configuration pages and advanced routing, it provides unmatched Modbus connectivity. The integrated webserver enables complete configuration of all module parameters like serial interface, baud rate, data bits, stop bits, or flow control.

Products are available in different versions for DB9 or screw terminal connection.
