MURR relay, time relay, optocoupler relay small volume chip relay wafer design, 35mm guide rail installation. Using the negative bridge insert, more than 24 relays can be used in parallel. Input voltage ranges from 24 volts to 240 volts AC/DC. Single or multiple contacts. Built-in anti-interference element to suppress interference. Input and output electrical isolation, effectively prevent electromagnetic interference. LED displays working status. Elastic terminal for more efficient wiring. Some modules have manual forced switching function. MIRO time relay housing width 6.2mm and 12.4mm with delay on delay off and a variety of functions rail installation using negative bridge insert with screw terminal and elastic terminal two wiring methods. Solid state (photoelectric coupling) relays Optocoupling relays are mainly used in the interface between two different signals, etc., or to isolate two different signals.
