The new 751-9402 controller features eight digital inputs and eight configurable digital channels that can function as either inputs or outputs. They are compliant with IEEE 2030.5, IEEE 1547 and SunSpec Modbus 700, allowing for dynamic I/O allocation based on application needs. Along with the digital inputs, this controller also includes two configurable analog inputs as well as two more additional analog channels that can be configured as inputs or outputs, all supporting current or voltage. It also features dual galvanically isolated RS-485 ports for integration with energy meters and field devices using Modbus RTU. Programming is done via free Codesys 3.5 software, supporting IEC 61131-3 languages and HTML5 visualizations through its built-in web server.
