Compact relays
August 1st 2006 Pilz Automation Technology has introduced a new range of compact safety relays that are multifunctional, have improved diagnostics, are easier to expand and that benefit from improved switching capacity. Included in the line-up is what is believed to be the world's first 12.5mm wide safety relay.
The PNOZsigma range is the fourth generation of volt-free contact safety relays from Pilz and includes a number of features requested by customers, such as international approvals to make life easier for exporters.
The range has been designed so that a smaller number of relays perform the functions that used to need a broader product range.
For example, the 22.5mm wide Category 4 PNOZ s5 safety relay monitors emergency stop switches, guard switches or light curtains and benefits from an integrated timer function.
The company says that, typically, the relays deliver the same functionality in 50% of the space required previously. It is now possible to install six safety outputs with a width of just 30mm. Relays contain a microprocessor that delivers improved diagnostics via six LED indicators. More articles from Pilz Automation Technology: |
