    1. Introduction and Block Diagram GV460, GV461, GV480 and GV481 represent a series of incremental encoder splitters with a most compact, space-saving design and with most versatile technical features. All models are fully identical except for the number of output channels (4 or 8 channels) and the system of potential separation.

    2. Electrical Connections and LED Function 2.1. Power Supply and LEDs The unit provides a 3-position screw terminal strip for supply from a 10 – 30 volts DC power unit. The current consumption is approx. 40 mA (no-load operation). The “Select” input terminal provides selection of the desired source encoder. Details will be described later.

  • Page 9: Impulse Inputs

    2.3. Impulse Inputs The 8-position DIL switch on the front side provides setting of the desired signal formats and levels. These settings are separately for each of the channels A / B / Z (see block diagram). For simplification, a short form of the four most common applications is shown below, with the encoder supply omitted: 2.3.1.

    2.3.4. Differential signals for encoder channels A and B, but single-ended marker pulse from proximity switch or photocell Besides the most common standard configurations shown before, the unit allows setting of any other input configuration (e.g. differential encoder inputs on channels A, /A, B, /B, but single- ended index signal on input Z (from a proximity switch, photocell or similar) The block diagram shows which of the DIL switch positions is responsible for each of the channels.

  • Page 11: The Outputs

    2.4. The Outputs All outputs provide the non-inverted and the inverted signals at any time, even when on the input side the inverted signals are not available. The potential situation between the outputs and other circuits is clearly explained by the block diagrams in chapter 1.
  • Page 12 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.
