Fieldbus H1 Pinout Information
The FBUS-HSE/H1 LD can be one of up to 32 devices connected to a
Fieldbus H1 network. The connection is made through one of the two 9-pin
male D-SUB Fieldbus H1 connectors on the FBUS-HSE/H1 LD, shown in
Figure 3-9.
Use a Fieldbus cable with a 9-pin female D-SUB connector to connect the
FBUS-HSE/H1 LD to a properly terminated Fieldbus network. When you
are only using an FBUS-HSE/H1 LD, the power hub is not being used for
power. For other F
OUNDATION
™
Fieldbus devices that use bus powering, you
would apply power to the hub, from which devices would get their power.
Refer to the Fieldbus Foundation
