Installation and Wiring
Type
Terminal
Mark
Terminal Name Description
Analog
input
AI1-GND Analog input 1
Voltage range of inputs: 0 to 10 V DC.
Input impedance: 22 kΩ.
AI2-GND Analog input 2
Either a voltage or current input, determined by
jumper J9.
Input voltage range: 0 to 10 V DC.
Input current range: 0 to 20 mA.
Input impedance: 22 kΩ (voltage input), 500 Ω or
250 Ω (current input) decided by J10
[2]
.
Digital
input
DI1- OP Digital input 1
Optically-coupled isolation compatible with dual-
polarity inputs.
Input impedance: 1.39 kΩ.
Voltage range for inputs: 9 to 30 V.
DI2- OP Digital input 2
DI3- OP Digital input 3
DI4- OP Digital input 4
DI5- OP
High-speed
pulse input
In addition to having the same features as DI1 to
DI4, DI5 can also be used for high-speed pulse
inputs.
Maximum input frequency: 100 kHz.
Input impedance: 1.03 kΩ.
Analog
output
AO1-GND
Analog output
1
Either a voltage or current output, determined by
jumper J7.
Output voltage range: 0 to 10 V.
Output current range: 0 to 20 mA.
Digital
output
DO1-CME Digital output 1
Optically-coupled isolation, dual-polarity open-
collector output.
Output voltage range: 0 to 24 V.
Output current range: 0 to 50 mA.
Note that CME and COM are internally insulated,
but are shorted externally by a jumper. In this
case, DO1 is driven by +24 V by default. Remove
the jumper link if you need to apply external
power to DO1.
FM- COM
High-speed
pulse output
Controlled by F5-00 (FM terminal output
selection).
Maximum output frequency: 100 kHz.
When used as an open-collector output, the
speci󶍾cation is the same as for DO1.
Relay
output
T/A-T/B
Normally-
closed (NC)
terminal
Contact driving capacity:
250 V AC, 3 A, Cos Φ = 0.4.
30 V DC, 1 A.
T/A-T/C
Normally-open
(NO) terminal
