November 4, 2009 – To increase flexibility and optimize every I/O point for machine builders and users, Beckhoff Automation introduced the EP2338 EtherCAT Box. With the rugged EP2338, Beckhoff enhanced its IP 67 I/O system with a dynamic 8-channel digital variant. The 8 channels on the EP2338 can be used either as inputs or outputs, which permits extremely flexible use of this compact and durable EtherCAT Box. This way, engineering efforts and spare parts inventory can be simplified significantly, since the inputs and outputs can be connected exactly as needed when the machine is wired. The moisture- and dust-resistant EP2338 EtherCAT Box has eight freely selectable digital inputs or outputs in one flexible device.
The filter constant of the inputs is 10 μs. The outputs handle load currents of up to 0.5 A, are short-circuit-proof and protected against inverse polarity. If a channel is used as an output, the input is read back in parallel and can additionally be used for short-circuit analysis. Pre-assembled cables from Beckhoff simplify EtherCAT and signal wiring, while helping prevent wiring faults so that commissioning time is optimized.
In addition to pre-assembled EtherCAT, power and sensor cables, field-configurable connectors and cables are available from Beckhoff for maximum flexibility. The signals are connected optionally via M8 (EP2338-0001) or M12 (EP2338-0002) screw type connectors. The EtherCAT Box family with direct EtherCAT interface expands upon Beckhoff’s IP 67-rated I/O system solutions. With these compact modules, which measure just 126 x 30 x 26.5 mm (H x W x D), the impressive performance of EtherCAT at 100 Mbit/s is retained down to each IP 67 box.
The EtherCAT Box system is particularly suitable for applications where space is limited or where a control cabinet is not viable, such in material handling and assembly modules in semiconductor production or in packaging machines. The low weight of the EtherCAT module also facilitates applications with requirements for a moving I/O interface, such as robot arms. Beckhoff Automation provides advanced, open automation products based upon proven technologies so that customers can implement high performance control systems faster and at a lower overall cost than traditional PLC and motion control systems. Beckhoff’s “New Automation Technology” product range includes PC based control, industrial PCs, automation controllers, operator interface, I/O, servo drives and motors.
