3. Applicable Encoders and Sensors
The converter can accept the following impulse sources:
The ZU252 converter can accept the following impulse sources:

Quadrature encoders with HTL level output (10 – 30 V) and either PNP or NPN or Push-
Pull or NAMUR characteristics, using A and B outputs wit 90° displacement

Single channel impulse sources like proximity switches or photocells, providing HTL
level at PNP or NPN or Namur characteristics

TTL / RS422 quadrature encoders with output lines A, /A ,B and /B

Symmetric single channel sources with TTL / RS422 output, providing differential
signals (i.e. A and /A)

Asymmetric single channel sources with TTL level (without inverted signals, i.e. A only)
In general, HTL encoders will be supplied from the same source as the converter itself.
For supply of TTL encoders, the unit provides an auxiliary output of 5.5 volts
(stabilized, max. 250 mA).
