Beckhoff Automation ep1816-3008

The EP1816-3008 EtherCAT Box with 16 digital inputs acquires the binary control signals from the process level and transmits them, in an electrically isolated form, to the controller. The state of the signals is indicated by light emitting diodes. The signals are connected via a 25-pin D-sub socket. The EtherCAT Box has two internal 3-axis accelerometers with 10 bits and a selectable resolution of ±2 g, ±4 g, ±8 g and ±16 g. The sampling frequency is 1 Hz to 5 KHz. Possible applications include the recording of vibrations and shocks/oscillations, and furthermore inclination measurements in all three axes. The sensors are supplied from the box supply voltage US. The auxiliary voltage UP is not used in the input module, but may be connected in order to be relayed downstream. Undervoltage detection (US and UP) is integrated and is signaled to the controller.
