Function Description
Specification
Multifunctional
DI
DI1
The factory default is valid when DI (DI1, DI2, DI3,
DI4, DI5) and GND are short-circuited when OP and
24V are short-circuited.
INPUT, 24V level signal, high level active, 5mA.

DI5
Multifunctional
AI/AO
AI
AI voltage/current input, voltage and current are
selected by jumper J5, the factory default is voltage,
if you want current, just adjust the jumper cap to the
C2 position. (Reference ground: GND)
Input voltage range: 0
～
10V (input impedance:
100KΩ),
input current range: 0
～
20mA (input impedance:
500Ω).
AO
AO provides analog voltage/current output, the
current is selected by jumper J2, the factory default
output voltage, if you want to output current, just
jump the jumper cap to the C position. (Reference
ground: GND)
0
～
10V DC voltage/0
～
20mA current.
Relay output
TA
It can be defined as a multi-function relay output
terminal.
TA-TC is NO
。
Contact rating:
250VAC/2A(COSФ=1),30VDC/1A.
TC
OC output
Y
It can be defined as a multifunctional collector output
terminal, which can be used as a high-speed pulse
output.
1. Switching capacity: 50mA/30V
2. Output frequency range: 0~50kHz
Power supply
+24V
The common power supply for the circuit of the
digital signal input terminal
Maximum output current 200mA
+10V
The circuit common power supply for analog input
and output terminals
Maximum output current 20mA
OP
The factory default is connected to +24V. When
using external signals to drive DI1
～
DI5, OP needs
to be connected to the external power supply and
disconnected from the +24V power supply terminal
External power supply input terminal
GND
Analog signal and +10V power reference ground
Digital GND
Communication
485+
RS485+
Standard RS485 communication interface, not
isolated from GND, please use twisted pair or
shielded wire.
Jumper J8 is for RS485 terminal resistor.
