ET-DO-16 module is equipped with 16 binary inputs having current capacity up to 6A.

ET-DO-8 module is equipped with 8 binary inputs having current capacity up to 10A.

They have galvanic separation.

ET-DO can receive information from CPU module ET-CP or directly from corresponding input module (working in ET-Directlink mode) by ET-BUS data bus.

ET-DO modules have internal diagnostic system, which transfers actual working parameters and error information to the CPU ET-CP. Programmer can use this data e.g for alarming needs or presentation of controller's status to a user.
