SKR - industry relay the universal relay SKR the time module STM the socket 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. 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. 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. features simple construction high contact load contact spring in Beryllium bronze safe wire diameter long life time large coil room electrical or mechanical status indication integrated manual actuation simple installation indelible scheme on socket or cover following international standards applications mostly used where a timedependent event must be headed switch panel making machine industry illuminations locking of functions gate control machine control 4 catalog 00 e / 04.03
