Smart configuration and logging
Setting management, report printing, and CSV logging with dedicated software LINKSHIP [free of charge]　 Go to LINKSHIP page

CSV logging	Compare and match set value lists	PC save and copy of set values	Prevention of misoperation	Quickly set up multiple units


Time-specified logging, such as 600 seconds, is also available. Custom logger software is also available.	Multiple lists of set values can be compared and collated.	It prevents errors in note-taking and manual entry, and reduces management effort and costs.	Settings and confirmations can be made on the PC screen, preventing misoperation of the main unit's buttons.	Even multiple units can be easily configured by simply writing the configuration data.

USB Type-C connector standard	Setup unit without LINKSHIP or PC required: Program Loader PL-5A　 [sold separately]

Power supply: 12 to 30VDC / 100 to 240VAC　[Select a model]
Isolation　
[General-purpose input type] Electrically isolated between power supply and other inputs/outputs.
[Line driver input type] Electrically isolated between power supply, frequency signal input, and other inputs/outputs.
