I/O Terminal Equivalent Circuit - Panasonic YA-1W Series Operating Instructions Manual

External Control Signal Connection

7.3 I/O terminal equivalent circuit

Spec.

Input terminal equivalent circuit
• To receive no-voltage ON/OFF contact signal from an external
equipment.
• External relay contact to be connected... 1 ohm or less,
T
Chattering ..........10 ms or less
Y
• Pulse amplitude of an input signal should be 0.2 s or more.
U

Output terminal equivalent circuit
• Open collector (NPN) output.
• Rated output is 24 VDC, 75 mA.
• Use a relay whose coil voltage is 24 VDC and coil current is
75 mA DC or less, and attach a noise adsorbing diode:
D (100 VDC, 1 A).
• Rated load of the emergency stop output: 5 A, 30 VDC.

Power to activate input/output
• It is necessary to apply 24 VDC of supply voltage between
24 VDC input and COM. Turn ON/OFF the power synchronous
to the control power of the controller.
• The power to be provided by customer:
• Voltage:
• Capacity:
• Apply noiseless stable power is applied.
E
To remove the common-mode noise, refer to the following figure
and input the capacitor.
* Recommended capacitor: Film capacitor 0.1 µF, 50 VDC.
