Festo introduces an innovative suite of safety products, including its new CIP safety module, that ensures the safe operation of pneumatic systems and lowers the risk of injury and system and product damage. Festo pneumatic safety solutions are compatible with the top industrial Ethernet protocols – EtherNET/IP, PROFITNET, and EtherCAT – which gives them near universal application.
The new CIP safety module connects directly to the safety controller, with no need for a safety I/O block, which simplifies wiring and can reduce cost by eliminating the requirement for separate safety I/O. The safety module offers one safe zone for up to a CAT4, Ple, and SIL3 safety level for safety sub-functions: safe-switch-off and prevented-unexpected startup.
The CIP safety module can also work with an integrated pilot air control valve for redundant shut-down of directional valves and an integrated pressure sensor to monitor pilot air. These are compatible with the Festo MPA-S and VTSA valve terminals. The CIP Safety module will be available in 2025.
Festo’s new flagship valve terminal, the VTUX, has been designed with safety in mind. VTUX valves feature negative overlap spools that allow for safe exhausting of compressed air in case a valve spool is in an indeterminate position. Festo will be incorporating additional safety features as the platform matures.
For those in the automotive industry that use safe I/O blocks, such as Allen-Bradley ArmorBlock Guard I/O modules, Festo offers its CPX platform with VTSA-F-CB valve terminal. This solution delivers three safe zones controlled by an external safety controller. The VTSA-F-CB offers up to a CAT3, Ple, and SIL3 safety level for safe-switch-off and prevented-unexpected startup. It also offers soft start/quick exhaust options.
For those applications outside the automotive industry that use safe I/O blocks, the MPA-S can also support safe zones with power supply modules, a soft start/quick exhaust option, and pilot air control valves. This valve terminal solution offers up to a CAT2, Pld, and SIL2 safety level for safe-switch-off and prevented-unexpected startup.
Festo’s new Automation Platform (AP) CPX-AP-A provides I/O and interfaces to valves terminals VTSA, MPA-S, and VTUX. The backplane performance of this new system can handle modern requirements for speed, capacity, security, and safety. The CPX-AP-A can also run in a hybrid mode that allows for remote and distributed valves and I/O.
With either the CPX or the CPX-AP-A, safety with valve terminals can be supported. Either system can monitor both pilot air pressure and voltage of each safe zone, and can provide feedback data used with safe instructions within the safety PLC.
