2.4.2 PNP Specification
(1) Input part
External Input Specifications (PNP Specification)
Item Specification
Input voltage 24 VDC r10%
Input current 7 mA per circuit
ON/OFF voltage
ON voltage --- 8 VDC max.
OFF voltage --- 19 VDC min.
Isolation method Photocoupler isolation
External devices
[1] No-voltage contact (minimum load of approx. 5 VDC/1 mA)
[2] Photoelectric/proximity sensor (PNP type)
[3] Sequencer transistor output (open-collector type)
[4] Sequencer contact output (minimum load of approx. 5 VDC/1 mA)
[Input circuit]
Note: The parameters are normally set to the
above port numbers before shipment.
Caution
If a non-contact circuit is connected externally, malfunction may result from leakage current. Use a
circuit in which leakage current in a switch-off state does not exceed 1 mA.
~ Input signals to the Tabletop Robot
At the default settings, the system recognizes the ON/OFF durations of input signals if they
are approx. 4 msec or longer. The ON/OFF duration settings can also be changed using
I/O parameter No. 20 (input filtering frequency).
