1. Compatibility Hint
This product is a successor model of the thousandfold approved converter type ZU251. The new
product is suitable for a 100% replacement of the previous model, however some differences
must be observed with DIL switch settings and parameter settings.
Some essential advantages of ZU252 compared to ZU251 are:
Maximum frequency 1 MHz (instead of 500 kHz)
Capability to accept even single-ended TTL input signals
(i.e. TTL inputs A and B only, without inverted signals /A and /B)
Setting of analogue f/-10V, +10V, 0-20 mA and 4-20 mA can be done by
supplementary DIL switch (no more PC required)
Enhanced auxiliary output 5 V / 250 mA for encoder supply
