Measures against drainage
Drainage resistance:increased by 10 times or more
* Based on SMC’s specific testing conditions (Oil proof test)
* Compared with the ISA2
Withstand pressure increased by Max.:600 kPa(3 times*1 compared with the ISA2)
*1 Compared with the ISA2 with a 0.2 MPa pressure gauge
High-pressure flushing
* The switch output will be OFF during flushing.
Noise reduction, Energy saving, Measures against clogging

Main Functions
Display OFF mode
Display OFF mode can be selected. The display can be turned OFF to reduce power consumption.
![](/assets/newproducts/en-jp/isa3/images/17.jpg)
Display color
The color of the main display can be set to change depending upon the output activity. The display color change makes visual identification of the output ON/OFF easier.

Unit conversion
The pressure unit displayed on the sub screen can be changed.

Displayed value compensation
The displayed value can be corrected within ±20% R.D. of the displayed value at the time of shipment.
Forced output
The output can be fixed to an ON/OFF state when starting the system or during maintenance. This enables the confirmation of the wiring and prevents system errors due to unexpected output.
Zero-clear of pressure value
The pressure value displayed on the sub screen can be cleared to zero.
