PS5—COM
Digital input 5
5. Both source and sink inputs are allowed, but
the input types must be the same
PS6—COM
Digital input 6
Analog input and
output
AI1
Analog input 1
1. Input range: AI1 voltage and current range:
0–10V, 0–20mA
2. Input impedance: 20kΩ during voltage input;
250Ω during current input
3. Voltage or current input is set through the
jumper.
4. Resolution ratio: When 10V corresponds to
50Hz, the min. resolution ratio is 5mV
5. Deviation: ±1% when the input reaches full
the measurement range at 25°C
AO1
Analog output 1
1. Output range: 0–10V voltage or 0–20mA
current
2. Voltage or current output is set through the
jumper.
3. Deviation: ±1% when the input reaches full
the measurement range at 25°C.

Communication
485+
RS485
communication
terminal
RS485 communication port, which can be set
as the master or slave through the Auto
Station. It is differential signal output. Whether
to connect the 120Ω resistor of RS485 is set
through the jumper.
