SKR - industry relay the universal relay SKR The strengths of the SKR industry relay lie in the mature and thoughtout construction. Over-average contact safety and life time, electrical and mechanical status indication as well as the unsurpassed construction from only six assemblies makes the relay to the excellent power switch. the time module STM 8 adjustable functions and 8 selectable time ranges: these are the special features of the time module STM. With only one version of the module all essential features as operating voltage, functions and time ranges are adjustable. The result: a simple and cost-effective warehousing. features • • • • • • Simple to handle screw-terminal and clear, rich in contrast labeled clamp identification, are the base for a problemles use. The ZKE/ZKX sockets permit a rapid and secure installation. The separated inputs and outputs are located at one level. There is also the possibility to plug a time module STM or other additional modules together with the SKR relay. applications simple construction high contact load contact spring in Beryllium bronze safe wire diameter long life time large coil room 4 the socket catalog 2002 e / 04.03 • electrical or mechanical status indication • integrated manual actuation • simple installation • indelible scheme on socket or cover following international standards • mostly used where a timedependent event must be headed • switch panel making • machine industry • illuminations • locking of functions • gate control • machine control type number key SKR 115 A ... 024VDC coil voltage VDC = direct current VAC = alternating current standard voltage VAC: 024, 115, 230 V VDC: 024, 110 options D = L = F = FL = double contact (AgCuNi) electrical position indication free wheel diode free wheel diode and electrical position indication B = without manual actuation T = push-button actuation C = current coil relay version SKR 085 A SKR 115 A SKR 122 A A = mechanical position indication standard: manual actuation manual actuation position indication free wheel diode LED display order samples • • • • • • • • • • • • SKR085 SKR085 SKR085 SKR085 A AF AL AFL VDC/AC VDC VDC/AC VDC SKR115 SKR115 SKR115 SKR115 A AF AL AFL VDC/AC VDC VDC/AC VDC SKR122 SKR122 SKR122 SKR122 A AF AL AFL VDC/AC VDC VDC/AC VDC catalog 2002 e / 04.03 5 SKR085 - industry relay, 8-pole Industry relay with two change-over contacts in different versions. contact specifications order numbers serial version SKR 085 A ...
