CHAPTER 5 Specification
Withstand high-voltage high-precision terminal B-565
Item Description
Number of input channels 20ch (200ch available when used with the extension terminal base)
* Possible to direct-connect or connect with the extension terminal connection
cable (sold separately) between the GLT400 and terminal unit, or between
terminal units.
