4.2. Incremental encoder HTL / 12-30V
The encoder may be supplied from the same source as the converter, or from another source.

4.3. Proximity switches, photocells etc.
This connection is fully similar to a HTL incremental encoder. With single-channel operation,
input B remains unconnected or can be used to select the output polarity. With use of two
independent counting events for forming the sum or the difference, input B operates as the
second counting input.
For use of sensors providing 2-wire NAMUR characteristics:

Set the inputs to HTL and NPN

Connect the positive wire of the sensor to the corresponding input and the negative
wire to GND.
4.4. HTL Input “Control”
The HTL control input available on terminal 10 provides programmable characteristics and
functions for activation of different commands (e.g. Reset, see parameter “Input setting)
4.5. Analogue outputs
The unit provides a +/-10V voltage output and a 0-20 mA / 4-20 mA current output at a
resolution of 14 bits, i.e. the voltage output operates in steps of 1.25 mV and the current output
operates in steps of 2.5 µA. The nominal load of the voltage output is 2 mA, the current output
accepts loads between 0 Ohms and 270 Ohms.
The analogue ground uses a separate terminal, which however internally is connected to the
GND potential of the power supply.
