ET1010 – Switching IO Expansion Module

ET1010 is a switching IO expansion module, including 4 switching inputs and 4 relay outputs. The module supports MODBUS RTU protocol, supports cascading, non-inductively expands the number of IO interfaces, and does not require configuration, plug and play, adaptive master-slave station, adaptive register address, has communication delay of milliseconds, and high-speed communication without packet loss or abnormality, hardware indicators present communication status in real time and other features. It can be used with the main device ET3410 for better results.
