4-1-1-3. Voltage / Current Type Sensor Connection
Contact type, overcurrent type, laser type, and other voltage / current type sensors of up
to
±
5V /
±
20mA can be connected. (The analog input option is a factory-shipped
setting.)
4-1-1-4. Voltage Output (V-OUT) Connection
The relationship between sensor type and output voltage is as follows:
Strain gauge
1mV/V ............ Approx. 2.0V
Voltage
5V ............. Approx. 5.6V
Current
20mA ............. Approx. 5.2V
4-1-2. SI/F Connection
This is a 2-wire serial interface to connect a UNIPULSE-manufactured printer, external
display, etc.
Up to three nonpolarized external devices can be connected. Use parallel two-core
cables, cabtyre cables, and the like for wiring.
