PR - PCB relay the PR-PCB relay PCB-Relay from the PR family are small relays. The version has forced guided contacts, 2 normally open contacts, 2 normally closed contacts. In the industrial electronic as well as in the control industry they are used as fail-save elements. The forced guided contact version are often used in control systems of high safe applications. features applications • • • • • • • devices of automation and control simple fail-save construction high switching power high load current extraordinary life time high contact force security distance according to VDE and CSA • minimal dimensions • the forced guided contact version, SUVA approved. 42 catalog 2002 e / 04.03 By using best materials and because of the simple construction the highest failsecurity was achieved. High precision in mechanical and electrical control guarantees the high and stable quality of the relays. type number key PR 4 ... 024 VDC coil voltage VDC = direct current standard voltage VDC: 024, 110 option F = flat version H = tall version relay version PR 4 (forced guided contacts) order sample PR 4 F 024 VDC - PCB-relay with forced guided contacts - flat version - coil voltage 24 VDC catalog 2002 e / 04.03 43 PR 4F - PCB relay PCB-relay with forced guided contacts, flat version with 2 normally open contacts, and 2 normally closed contacts order numbers serial version PR 4F ..
