Furthermore, cascaded configurations allow remote selection and switch-over between several input encoders. GV 470 is built into a most compact and space-saving housing for mounting on DIN rails. The following drawing explains the principle of function with one of the eight output channels:... -

2. Electrical Connections and LEDs 2.1. Power Supply and LED Assignment The unit provides a 3-position screw terminal strip for supply from a 10 – 30 volts DC power unit. The current consumption is approx. 100 mA (no-load operation). The “Select” input terminal provides selection of the desired source encoder. Details will be described later. -
Page 6: Outputs
1, 3, 5 and 7 of the cascading output must be connected to the corresponding pins of the cascading input of the follower unit. An appropriate ribbon cable connection is available under motrona part # FK470 FK470 GV47001b_e.doc / Feb-08... - Page 7 Cascaded units allow selection of the active source encoder via the encoder select input on the 3-position power connector (see also block diagram): LOW (or open): outputs refer to the encoder input of the same unit HIGH (10 – 30 volts): outputs refer to the encoder input of the preceding unit It is possible at any time to switch over from one to the other source encoder during operation, therefore cascaded units can also operate as a cross-switch.
