ERTIFICATIONS
CE & FCC
These devices are designed to meet all applicable EM interference
and emission standards. However, as they are intended for use
installed on motherboards, and inside the chassis of industrial
PCs, important care in the selection of PC and chassis is important
to achieve compliance for the computer as a whole.
UL & TUV
No DC voltages above 5V, and no AC voltages of any kind, are
consumed or produced during normal operation of this device.
This product is therefore exempt from any related safety
standards. Use it with confidence!
TRU-
ISO™ STATEMENT
Our Tru-
Iso™ products are designed under IPC
-2221B Generic
Standard on Printed Board Design. The circuit is isolated with a ≥
300mil gap between all signal and plane layers between the ports
and the PC, and a ≥ 100mil gap
port to port. These gaps are rated
under IPC-2221B at a peak working voltage of 1500V (Port to PC)
and 500V (Port to Port). Our circuit uses a chip-level high-
frequency DC-DC isolator which is rated at 2500VRMS for 1
minute under UL 1577 optical isolators standard. This isolation
component has an over 50 year isolation lifespan even if the
isolation voltage potential is in excess of 350 volts AC. Tru-Iso
products are also designed to meet EN60601 medical electrical
equipment standard. TRU-
ISO™, for true si
gnal isolation.
