Input Ports
Because each of CIE-H14A
’
s input ports are isolated by photo-couplers, users don
’
t need
to worry about the polarity. The circuit of the input port is shown in the figure below.
Figure 1-9 a circuit of the input port
The voltage specification of the input port is as follows:
Over 4.5V
H
1
Under 1.2V
L
0
Max. Input Voltage
DC 24V
Polarity
Auto Polarity
Table 1-3 the voltage specification of the input ports
The input port is interfaced with a 5mm terminal block. Thus, use a (-) shaped
screwdriver to connect it with the user device.
