Plug-in modules for safety relays
June 30, 2008 by Manufacturing AUTOMATION
Pilz Automation Safety has introduced two new modules in the PNOZsigma range of slim line safety relays. The first of these models, the PNOZ s7.1, features three normally open safety contacts. In addition, the PNOZs7.1 incorporates a separate feedback loop that enables the 17.5-mm module to be used as a stand-alone safety relay. When a PNOZ s7.1 is used either as a stand-alone unit or with a PNOZsigma base unit, further expansion is possible by connecting a maximum of 10 PNOZs7.2 modules, each having four normally open safety contacts and one normally closed auxiliary contact. Alternatively, a PNOZ s7.2 can be connected to a base unit as a single expansion module. As with the PNOZ s7.1, the PNOZ s7.2 measures 17.5 mm wide.
