(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)

(3) Output terminals (OUTPUT) Y0 to Y7 and BUSY
Result of logical calculation output
- Specify in item rFINAL OUTPUT COND on the [OBJECT TYPE COND] menu.
=> See page 10-8 to 13.
Y0
to Y7
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 7OUTPUT STATUS in the "I/O
SETTINGS" menu. Seetings => See page 11-1. Time chart, etc. => See page 11-
4 to 11-15.
(2) Input terminals (INPUT) X5 and X6
X6
Parallel selection input
(External input/image change etc. and measurement
number specification (upper bits))
Specify in item 6PARALLEL INPUTX6 on the [I/O
SETTINGS] menu.
X5
Parallel selection input
(External input/reference image registration etc. and
measurement number specification (lower bits))
Specify in item 5PARALLEL INPUTX5 on the [I/O
SETTINGS] menu.
(See page 11-1 and11-2.)
