The minimum pulse duration on the Reset input (C) must be 5 msec.
4.4 Adjustable analogue output (LD251 model only)
A voltage output is available, operating in a range of 0 ... +10 V or –10 V ... +10
V according to setting. At the same time, a current output 0/4 – 20 mA is
available. Both outputs refer to the GND potential and the polarity changes with
the sign in the display. The outputs are proportional to the display value and
provide a 14-bit resolution.
The maximum current for the voltage output is 2 mA and the load on the
current output can vary between 0 and max. 300 ohms.
The response time of the analogue output at each change of the encoder
position is approx. 7 msec.
4.5 Optocoupler (transistor) outputs (LD252 model only)
Outputs provide programmable switching characteristics and are potential-free.
Please connect terminal 8 (COM+) to the positive potential of the voltage you
want to switch (range 5V....35V). You must not exceed the maximum output
current of 150 mA. If you switch inductive loads, please provide filtering of the
coil by means of an external diode.
The optocoupler outputs provide a response time of approx. 5 msec with
resistive load.
