1. Description of the module
The Z-4-Fold Level Shifter PR0095 gives out the signal of an incremental encoder
potential-free to 4 outputs. At this the input signal to the evaluation electronic and to
the 4 outputs is separated. Due to an input level in the range of 4 to 24V DC it is
possible to use 5V and 24V encoders. All 4 outputs are also potential-free among
each other and provided by separately supplied voltage in the range of 4V to 6V.
A voltage converter internally produces a 5V supply voltage for 5V incremental
encoder (max. 0,9A). If the internal 5 volt supply or the feed-in of the module for
supply of the incremental encoder is used there is no electrical insulation to the
evaluation electronic.
A micro controller assumes the separation, interlocking of jitter, recognition of
direction as well as the generation of the output signals within the module. Additionally
a plausibility check of the input signals is carried out.
1.1. Purpose of use
The module transforms the encoder signals, which are inducted by a commercial
encoder. These signals can reach a level from 5 up to 24V DC. A potential free
transformation to an output level of app. 5V (depending on the supply voltage of the
output and on the load) with a RS 422 trait takes place.
Additionally, pulse frequency of the output levels can be given in partition ratios of
1/2/4/8/16/32/64/128 and 256, whereas the counting direction can be negated. This
requires only turning a DIP-switch. Partition ratios refer only to the encoder’s counting
signals (K1 und K2), the zero encoder signal is given undivided.
The module’s input frequency is max. 100 kHz.
The module is connected via lockable header strips and is destined for top hat rail
mounting (35mm).
The frequency division is inactive, the counting direction reversal is switched of
and the partition ratio is set to “1” on delivery.
