5.2 Incremental encoders HTL / 12-30V
The encoder can be supplied by the same source as the converter or by another
source.
5.3 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 in order to obtain
the sum or the difference, input B operates as the second counting input.
For use of sensors providing 2-wire NAMUR characteristics:
1. set the inputs to HTL and NPN;
2. connect the positive wire of the sensor to the corresponding input and
the negative wire to GND.
5.4 CONTROL input
CONTROL input available on terminal 10 provides programmable characteristics
and functions for the activation of different commands (e.g. Reset, see section
“11.7 Input settings“ on page 66).
5.5 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 and 270

.
The analogue ground uses a separate terminal, which however is internally
connected to the GND potential of the power supply.
