1. 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 on the title page.

For vice-versa conversion of level and direction signal, see type PU202.

2. Construction, 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.

3. 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 (24V supply will cause pulse output with 24V 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 (+24V).

For encoder supply, an auxiliary voltage of +5 V / 100 mA is available at pin 4 of the input

connector (Sub-D-9 male). This voltage can also be taken from the screw terminal marked

“+5V”.

For use of the +5V auxiliary voltage at the input connector or the screw terminal, you must set

positions 7 and 8 of the 8-position DIL switch to “ON”.

Warning!

Never, with DIL switch position 7 and 8 “ON“, any external voltage must be

applied to input connector pin 4 or to screw terminal marked “+5V”! This

would cause irrevocable damage to the unit!

4. 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. Connection of the Impulse Input

5.1. Where at the input you use a shaft encoder which needs to be

supplied by the PU204 unit:

•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).

5.2. Where you use an encoder with separate supply, or the encoder

simulation of a drive:

•Set DIL-switch 7 to “OFF”, 8 to “ON”.

•Connect the screen to GND pin 5 on the PU204 side.

5.3. Where you like to use fully differential mode:

•Connect only the impulse lines.

•Set DIL-switch 7 to “OFF”, 8 to “ON”.

•Connect the screen to GND pin 5 on the PU204 side.
