Pilot valve terminal features flexible connections

12 June 2013

The valve terminal VTOC from Festo is said to be particularly suitable for pilot control of process valves in the semiconductor, photovoltaic, flat-panel, biotech, pharmaceutical and process industries – and can now be specified with a customised pin allocation.

The valve terminal – for up to 48 3/2-way valves – can be used wherever safety considerations require pilot valves with spring return. It is said to be suitable for reliable pilot control in gas box applications owing to its separate conductive tracks and push-in connectors. It also features double-pin actuation of each coil, which means that the valves do not automatically switch through on the circuit board in the event of a short circuit. External isolation can be incorporated for additional interlocks.

The VTOC also offers multi-pin plug connection with Sub-D plug or flat cable with different outlet directions. In addition, the valve terminal can be connected on IO Link via an M18 connector, or to numerous Fieldbus and Industrial Ethernet networks using Festo’s modular node. The highlight, however, is said to be the customised pin allocation, which provides simple and safe configuration into critical control systems, whether a multipin or a communications network is used.
