TRANSPORTATION AND INSTALLATION MANUAL

As input signals, no-voltage contacts or transistor open collector inputs are used.
No-voltage contact specifications:
Contact rating: 24 VDC, 10 mA or over (circuit current: approx. 7 mA)
Minimum contact current: 24 VDC, 1 mA
Contact impedance: 100 or less
Transistor specifications:
Withhold voltage between collector and emitter: 30 V or over
Current between collector and emitter: 10 mA or over (circuit current: approx. 7 mA)
Leak current between collector and emitter: 100 µA or less
By using the 24 VDC power of the controller, a relay, solenoid valve, etc., can be driven.
When the external power is used, GND of the external power should be common to
GND (PG) of the robot controller.
Output specifications:
Rated voltage: 24 VDC
Rated current: 100 mA
• If the 24 VDC power supplied from the robot controller is used, the total current
should be 2 A or less.
• When the external power is used, the total current should also be 2 A or less.
• When a relay or solenoid valve, etc., is connected, it is necessary to use a surge
killer or diode to absorb the surge voltage.
