4) Wiring description of control terminals
a) Analog input terminal:
Due to weak analog voltage signal, it's easily influenced by external interference, shield cable is
commonly used and wiring distance is as short as possible, which should not exceed 20m as shown in
Figure 3-7. In the occasion where certain analog signal is seriously interfered, the side of analog signal
source should be installed with filter capacitor or ferrite core as shown in Figure 3-7.
Name
28-core terminal, connect with optional cards (I/O expansion
card,PLC card, various bus cards, etc)
Optional: OC, differentiation, rotary transformer, etc
External keyboard
Select if PE connects with GND. In the occasion with interference,
connect PE with GND to enhance anti-interference. Connection
by default. (As shown in Figure 3-6, short circuit of 1-2 is
connection between PE and GND, short circuit of 2-3 is no
connection between PE and GND)
Select if PE connects with COM. In the occasion with interference,
connect PE with COM to enhance anti-interference. Connection
by default. (As shown in Figure 3-6, short circuit of 1-2 is
connection between PE and COM, short circuit of 2-3 is no
connection between PE and COM)
Select if CME connects with COM. No connection
by default. (As shown in Figure 3-6, short circuit of 1-2 is
connection between CME and COM, short circuit of 2-3 is no
connection between CME and COM)
Decide output type of analog output terminal AO1 is voltage or current
output. Voltage output by default. (As shown in Figure 3-6, short circuit
of 1-2 is voltage output, short circuit of 2-3 is current output)
Output voltage range: 0V-10V
Output current range: 0mA -20mA
Decide input type of analog input terminal AO1 is voltage or current
input. Voltage input by default. (As shown in Figure 3-6, short circuit of
1-2 is voltage input, short circuit of 2-3 is current input)
Input voltage range: DC 0V-10V
Input current range: 0mA -20mA
OP terminal connects +24V or COM through J9 jumper. +24V
connection by default. (As shown in Figure 3-6, short circuit of 1-2 is
OP and +24V connection, short circuit of 2-3 is OP and COM
connection)
If using external signal to drive DI1~DI5, OP needs to connect with
external power, and pull out J9 jumper
