Fieldbus devices can be connected to the Power Hub with shielded

or unshielded twisted pair fieldbus cable. The controller (host), if

present, is considered to be a device.

The Power Hub provides a minimum of 30mA of power-conditioned

current for each Device Port. If the current needs of a fieldbus segment

exceed the capability of a Device Port, the Auxiliary Port can also be

used to provide additional power-conditioned current.

The Power Hub can supply up to 315mA of power-conditioned

current for all Device Ports and the Auxiliary Port. The Power Hub can

be mounted on a 35mm DIN rail. For applications where AC power is

not available, the Power Hub can also be mounted on a battery pack

(accessory FCS-A11) for fieldbus power in the field.

Current limiting SpurGuard™ protection for each Power Hub

Device Port limits the current draw of an attached cable and device and

protects against short circuits. A short circuit in a spur cable or device

will not take down the entire segment. The remaining devices on the

segment continue to operate normally.
