Valve terminal ranges get low-cost networking connectivity

12 December 2012

Festo has extended the reach of its VTUG and MPA-L valve terminals and added a low-cost connection module for use with fieldbus or industrial Ethernet networks, a move which allows OEMs and machine builders to connect the valve terminals directly to protocols such as CANopen, Profibus, EthernetIP and DeviceNet, reducing installation and engineering costs.

Using its dual purpose connector, the valve terminals are configured and delivered complete with an M18 connector. This allows connection directly to the industry standard IO-Link network or, by fitting a separate CTEU network module connection to many Fieldbus or industrial Ethernet protocols are possible.

Whether multipin, IO-Link or network connection, the pneumatics do not change. The design of the circuit stays the same however it is connected electrically, enabling OEMs to reduce design and drawing costs and to access Festo’s ‘plug and work’ philosophy.

The CTEU bus node module includes a range of diagnostics functions which helps reduce downtime and machine failure, for example, by identifying overvoltage and short circuits.

The VTUG terminal is an extension to Festo’s standard valve range and is an aluminium sub-base valve terminal that can accommodate up to 24 valve positions, saving users wiring and control cabinet space. The MPA-L offers individual modularity with up to 32 positions – these positions can be a mixture of three different valve sizes matching the user’s application, saving compressed air.

High level IP65/IP67 protection also enables use under harsh ambient conditions
