Output
HDO~CME
High speed pulse
output / open
collector output
It can be used as high speed pulse output or open collector
output which is determined by function code P5-00.
High speed pulse output: maximum frequency is 100kHz
Open collector output :Optical coupling isolation, dual
polarity
Output voltage range: 0V~24V
Output current range: 0mA~50mA
Note: The CME is internally insulated with the COM, but
they have been short circuited externally (HDO is driven by
+24V by default prior to delivery).

3) Description of connection of control terminals
a) Analog input terminal
Since the weak analog voltage signal is easy to suffer external interferences, it needs to employ shielded
cable generally and the length should be no longer than 20 meters, as shown in Figure 3-15. In case the
analog signal is subject to severe interference, and filter capacitor or ferrite magnetic core should be
installed at analog signal source side, as shown in Figure 3-16.
