The minimum pulse duration on the Reset input (C) must be 5 msec.
1.4. Adjustable Analogue Output (IX 346 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 bits resolution.
The maximum current on 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 to changes of the encoder position is approx. 7 msec.
1.5. Optocoupler (transistor) outputs (IX 437 only)
The outputs provide programmable switching characteristics and are potential-free. Please
connect terminal 8 (COM+) to the positive potential of the voltage you like to switch
(range 5V....35V). You must not exceed the maximum output current of 150 mA. Where 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.
