EtherCAT IP67 I/O modules for harsh environments


General DPN

Beckhoff Automation has released IP67-rated EtherCAT Box I/O modules, an expansion of the Beckhoff Fieldbus Box line. The addition allows for “machine mount” installation and not just in an electrical cabinet. Module dimensions are 126 x 30 x 26.5 mm (H x W x D).

The EtherCAT connection between modules is established via screened M8 screw connectors. Sensors and actuators are also connected via screw-type M8 or M12 connectors as required. Beckhoff Automation offers a cost-effective assortment of these and many other connectors for optimized cabling. Communication via standard Ethernet cables permits networking of the EtherCAT Box modules over distances of up to 100 m.

The EtherCAT Box modules cover the traditional range of requirements for IP67 I/O signals: digital inputs with different filters (3.0 ms or 10 µs), digital outputs with 0.5 or 2 A output current, analog inputs and outputs with 16 bit resolution, thermocouple and RTD inputs, and stepper motor modules. Modules with time stamp inputs are also available for eXtreme Fast Control technology (XFC).
