Power is supplied via the H1 Fieldbus. A two-wire cable according to

Fieldbus speciﬁcation serves as carrier of both power and digital data

for multiple sensors. This cable can be operated in two versions:

l via an H1 interface card in the control system and additional power

supply

l via a Linking device with HSE (High speed Ethernet) and

additional power supply according to IEC 61158-2
