(4) Input/output port
The input/output terminals are isolated by photocouplers, to prevent malfunctions due to noise.
Use them within the rated range. The specifications of the input/output ports are listed below.
12/24 VDC
10.5 to 26.4 VDC
ON: 10.5 V or less OFF: 5 V or more
ON: 3 mA or less OFF: 1.5 mA or more
3.3 k
ohm
12/24 VDC
10.5 to 27 VDC
20 mA DC
NPN transistor, open collector
1.2 V or less (20 mA)
Isolated by photocoupler
1 ms or less (OFF to ON, ON to OFF)

BUSY
When "BUSY" is active, this terminal outputs an ON signal while the IV-S20 is
executing the measurement and opening the all set menu.
When "READY" is active, this terminal outputs an ON signal while the IV-S20 is
waiting for a trigger.
- To specify "BUSY" or "READY," go to item
