ASI bus interface for pneumatics

A pneumatic valve block, VTS02, with an interface to the ASI actuator sensor bus system is being launched by Robert Bosch.

The ASI interface is said to provide an economical method with no need for terminal boxes, or cable harnesses and fewer input/output modules on the controller. The cycle time of the ASI is less than 5ms and it can be fitted with a maximum of 31 slaves. Transportation is approximately 100m in total.

It is claimed the ASI offers clear cost savings in installation, running cost are lower than standard cabling, and planning, configuration, diagnostics and product replacement are all simpler.
