IF50
Applicable encoders and sensors
The converter can accept the following impulse sources:
1. 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
with 90° displacement
2. Single channel impulse sources like proximity switches or photocells,
providing HTL level at PNP or NPN or Namur characteristics
3. TTL / RS-422 quadrature encoders with output lines A, /A ,B and /B
4. Symmetric single channel sources with TTL / RS-422 output, providing
differential signals (i.e. A and /A)
5. 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.
The unit provides an auxiliary 5.5 volts output (stabilized, max. 250 mA) to
supply TTL encoders.
