Basic manual for CP-1004 module
TXV 110 04
14
Delay from log. 0 to log. 1
5 µs (DI0 - DI3)
5 ms (DI4 - DI7)
Delay from log. 1 to log. 0
5 µs (DI0 - DI3)
5 ms (DI4 - DI7)
Minimal size of captured pulse
50 µs
Input pulse overloading
max. 250 V (t < 10 ms)
* DI0 to DI3 inputs can be used as a special inputs (see chapter 2) and DI4 to DI7 inputs as an
analog inputs (see table below).
Note! It is necessary to be aware of GND terminals in groups 24 V DC and DIGITAL / SPECIAL
INPUTS are galvanically connected inside the system. It is not wantable to connect GND
terminal in DIGITAL / SPECIAL INPUTS group with a minus pole of power supply supplying
both the system and inputs, because the loop would be closed through the second GND ter-
minal and would cause possible disturbing signal inducing.
