■ Overview The new 3RS18 coupling relays are couplers in the well-proven standard 22.5 mm timing relay enclosure. The series comprises relays with 1, 2 and 3 changeover contacts with screw and spring-type connections for combined voltages and wide voltage ranges. ■ Technical specifications © Siemens AG 2009 Permissible residual current Of the electronics (for 0 signal) mA 2 Temporarily flowing capacitor charging currents On energizing supply voltage mA 450 for ≤ 500 μs 1) Note the short-circuit limitation for control with the semiconductor version! 1) Function display LED yellow 3TX7, 3RS18 Coupling Relays 3RS18 Coupling Relays with Industrial Housing Siemens LV 1 T · 2009 Relay couplers ■ Application Typical applications are found wherever solid-state compatible contacts are required and equipment with a wide voltage range is implemented.
