Functional definition of the terminal
PW
External power
terminal
Connect to +24V by factory default.
When DI1-DI6 need to be driven by
external signal, PW needs to be connected
to external power supply. It also should be
disconnected from the +24V.
Analog
input
AI1-GND
Analog input 1
1. Input range:
DC 0-10V/0-20mA, decided by toggle
switch S2 on TB board:
0-10V or 0-20mA can be selected by the
position of S2.
2. Input impedance: 20KΩ at voltage input
and 250Ω at current input
Analog
input
AI2-GND
Analog input 2
1. Input range:
DC 0V-10V / -10V~+10V, decided by
toggle switch S3 on TB board.
0-10V or -10V~+10V can be selected by S3
position.
2. Input impedance: 20KΩ for 0-10V or
-10V~+10V input.
Digital
input
DI1-PW
Digital input 1
Photoelectric converter is internal and
functions of each DI can be programmed by
parameters.
Input conditions:
maximum DC30V/8mA.
Please refer to note 1.
DI2-PW
Digital input 2
DI3-PW
Digital input 3
DI4-PW
Digital input 4
DI5-PW
Digital input 5
DI6-PW
Digital input 6
HDI-PW
High speed pulse
input
Besides functions of DI1 ~ DI6, it can also
be used for high-speed pulse input.
Maximum input frequency: 100kHz
Analog
output
AO1-GND
Analog output 1
Voltage or current output is decided by
toggle switch S1 on the TB board.
Output voltage range: 0~10V DC
Output current range: 0 ~ 20mA
AO2-GND
Analog output 2
Output voltage range: 0~10V DC
Digital
output
DO1-CM
Digital output 1
Optical isolation, single polarity open-
collector output
Output voltage range: 0V-10V
Output current range: 0-50mA
Refer to note 2.
DO2-CM
Digital output 2
