The is designed for galvanic isolation of two devices 2N Helios IP Wiegand Isolator
®
with separate power supply and interconnected via the Wiegand bus. The 2N Helios
®
protects the interconnected devices against communication IP Wiegand Isolator
errors and/or damage.
Connection of the to a security system unit is a typical 2N Helios IP Card Reader
®
example of application.
Function:
The separates galvanically a two-wire Wiegand bus in 2N Helios IP Wiegand Isolator
