Behavior with short-circuit/overload
Should a short-circuit or overload occur on a transistor output,
this output will switch off. The output will switch on up to
maximum temperature after the cooling time has elapsed.
This time depends on the ambient temperature and the
current involved. If the fault condition persists, the output will
keep switching off and on until the fault is corrected or until the
power supply is switched off (
circuit/overload with EZ..-D.-T..”, Page 393).
Connecting analog outputs
EZD-RA.. and EZD-TA.. each have an analog output QA 01,
0 V to 10 V DC, 10 bit resolution (0 to 1023). The analog
output allows you to control servo valves and other final
controlling elements.
Caution!
Analog signals are more sensitive to interference than
digital signals. Consequently, more care must be taken
when laying and connecting the signal lines. Incorrect
switching states may occur if they are not connected
correctly.
