    Please find all respective hints and rules on www.motrona.com/download.html --> “[General EMC Rules for Wiring, Screening and Earthing]”. 1.4 Cleaning, Maintenance and Service Notes To clean the front of the unit please use only a slightly damp (not wet!), soft cloth.

  • Page 5: Introduction

    2. Introduction PU204 is designed to convert impulse levels from a TTL or RS422 format to a 10 … 30 V HTL format. At same time, the unit is suitable to convert the information of direction from the quadrature format to other usual standards like shown in the pulse diagram below.

  • Page 6: Construction And Dimensions

    3. Construction and Dimensions The unit is designed as a PCB with a plastic frame for direct and easy DIN rail mounting. The impulse inputs are available on a 9-pin SUB-D-connector (male). The outputs are available on a 9-pin SUB-D-connector (female). For power supply of the unit and of encoders, two 3-position screw terminals are available.

  • Page 7: Power Supply

    4. Power Supply The unit needs a 10 … 30 VDC supply. The level of the supply voltage automatically determines also the level of the output swing (24 V supply will cause pulse output with 24 V level also). The supply voltage can either be applied to the screw terminals marked “GND” and “+24V”, or also via the female SUB-D-9 output connector, using pin 5 (GND) and pin 4 (+24 V).

    5. Setting of the Direction Signal The unit, at the output, can use three different modes to indicate the sense of rotation. Output modes can be selected by the 8-position DIL switch on the print: 5.1. Indication of direction by phase displacement (quadrature pulses) 5.2.

  • Page 9: Connection Of The Impulse Input

     Set DIL-switches 7 + 8 to “ON”.  Supply the encoder from pins 4 and 5.  Connect the screen to the supply minus wire at the PU204 side (pin 5). 6.2. Where you use an encoder with separate supply, or the encoder simulation of a drive: ...
