1 LZS, LZX Plug-In Relays Relay couplers Overview The LZX complete units and accessory parts previously available are no longer listed in this catalog. They can still be supplied however in limited quantities. In their place you will now find the new LZS types. LZS complete units are fully compatible with their predecessors, the LZX complete units. The LZX plugin relays have not been changed and are used accordingly in both the LZS and the LZX series. Due to differences in geometry the LED modules, plug-in bases, fixing brackets and labels can be combined and/or used in only the respective series, LZS or LZX. List for converting from LZX to LZS relay couplers: Prices for the new LZS series are lower than for the previous LZX series. In addition the LZS series offers not only service-proven screw connections but also variants with push-in. The following conversion list will help you to change over from the LZX types previously sold to the new LZS types. Please contact your regional adviser if you have any questions.

2 LZS, LZX Plug-In Relays Siemens AG 2008 Relay couplers Design Function Plug-in relay coupling links can be ordered complete or as single modules. Mounting The relays are plugged into the base and this is snapped onto a TH 5 standard mounting rail according to EN A fixing bracket can be ordered for the MT series that Surge suppression additionally fixes the relay into a plug-in base (under conditions of increased mechanical stress). For the RT and PT series, a combined fixing and ejection bracket is available which can be used to remove the relay where access is difficult, for example, when relays are mounted side-by-side. They can be mounted as required. Logical disconnection In accordance with the technical specifications of electronic systems, the coupling links have a lower power consumption. In the versions equipped with LEDs, these indicate the switching state. The LZS: PT/MT relay couplers have a test button. This can be used to force the relay coupler into the tripped state and to lock it. This is indicated by a raised petrol-colored lever. The V DC relays LZX:RT and LZX: PT with LEDs can be supplied with, all others without integral surge suppression (freewheel diode connected in parallel with A1/A2). The positive supply voltage must be connected to coil terminal A1. The for the contacts and the for the coil are arranged on separate levels, e.g. above for contacts and below for coil. Logical isolation is not necessarily safe isolation. Safe isolation For safe isolation, transfer of the voltage of one circuit to another circuit is prevented to a suitable degree of safety (requirements and tests are described in EN in Appendix N). Control with solid-state output In the case of solid-state outputs (e.g. BERO) with overload and short-circuit protection, you must make allowance during configuration for the temporarily flowing capacitor charging currents This is possible, for example, by using a suitable LZS relay coupler. /160
