Space-saving Safety Relays

Two new modules in the vendor’s PNOZsigma range of slim line safety relays enable the number of contacts to be expanded considerably, thereby offering the potential for cost and space savings compared with traditional safety relays

The first of these models, the PNOZ s7.1, features three normally open safety contacts. It is connected—by means of a simple plug—to a PNOZsigma base unit safety relay type PNOZ s1, s2, s3, s4, s5, s6 or s6.1. 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 PNOZ s7.2 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 17.5mm wide.
