Smart series connection with several doors
Packaging machines often have many doors so that easy access to the machine is guaranteed during set-up mode or for maintenance purposes. More than ten doors in a safety circuit are not uncommon. The smart HOLDX R2 process guard locking was developed for exactly this kind of applications.
Thanks to an intelligent and simple wiring concept, up to 30 HOLDX R2 can be easily connected in series without giving up the diagnosis options. This allows individual evaluation of each participant without the need for an additional gateway. It is also possible to evaluate the information from the HoldX R2 on any commercially available control unit. SSP offers ready-to-use functional modules for controllers from Siemens, Beckhoff, Rockwell and B&R. Thus, the HOLDX R2 provides more than 300 pieces of information for diagnosis on the control unit.
