How it works

The ETCio 100 has two analog inputs and outputs with a 12-bit resolution. The analog output voltage range can be individually programmed between 0 to +10 V. In addition, the device has six digital inputs and four digital outputs. The outputs are short circuit protected.

The configuration of the ETCio 100 is made by the EtherCAT master device by writing EtherCAT objects.

Board-Level Product

The embedded board version of the ETCio 100 can be easily integrated in customer specific devices. Furthermore, customized versions with custom I/O interfaces, individual form factors or connectors can be developed by HMS in a short time and at reasonable prices.
