The prime function of interface units is to connected controller and the interface unit. This provides the act as a trouble-free adapter element between standardized greatest savings for the user. The use of interface units reduces plug connectors and point-to-point wiring or other connection the individual circuitry, which reduces labor and installation time systems. and also hidden costs, in particular a reduction material costs following a reduction in the number of individual cables and Interface units consist of the following individual components: leads, cable ducts, terminals and terminal blocks required. Extruded profile for inserting the PCB The transition to point-to-point wiring takes place directly at the End plates for fitting on the mounting rail interface element. Clip-on feet for locking on standardized mounting rails TS 32 and TS 35 PCB with connecting and indicating elements, DIN plug connectors and ample marking facilities for equipment identification The plug connectors used for the interface units can be divided into the following groups: Plug connector to IEC 603-1/DIN 41651 Sub-miniature plug connectors (SUB-D) to IEC 807-2/ Users have a choice between screw, tension clamp or spade DIN 41652 connections for connecting actuators and/or sensors. As an Plug connectors for PCBs to IEC 603/DIN 41612 and option, interface units can also integrate additional functions DIN 41615 such as status indicator, signal disconnector, fuses or shielding. ELCO plug connectors for hazardous area applications Identification systems make it easier to trace the signals to the corresponding element. Advantages of the interface units: Two- and three-tier PCB terminals save space RSF interface units for pre-assembled leads with plug Conventional point-to-point wiring only needed on one side, connectors to IEC 603-1/DIN 41651 thus saving costs Greater safety, preventing wiring errors Optional: status LED on the interface units Rapid troubleshooting with additional test and measuring devices Simplified setup and documentation Interface units let users implement pioneering concepts in switchboard design with potential for rationalization. Customized wiring concepts can also be solved rationally through the use of Passive interface for 10 64 signals for adapting pre- special interface units. assembled leads with plug connectors to IEC 603-1 / DIN 41651 to screw or tension clamp connection systems. When used in combination with a status indicator (LED), this guarantees rapid information about the switching state of incoming and outgoing signals. A.2 Interface Units
