Function: MBHC-FB-4.GT*

The motherboard is a system component of the FieldConnex ^®Power Hub, a modular fieldbus power supply for 4 segments. It is the wiring interface for one gateway, one advanced diagnostic module, and 4 power supply modules. The power supply supports explosion protection, e. g., the high‑power trunk for long cable lengths and high device counts. The Power Hub supports advanced diagnostics for fast fieldbus commissioning and online monitoring.

Sockets for all modules enable simple installation and replacement without tools. Wire connections can be selected as spring terminals or screw terminals.

The motherboard supports a choice of gateways for different host protocols. A PROFIBUS PA master for each segment enables short bus cycle times. The DCS can access the advanced diagnostic module directly via the gateway without additional wiring or configuration.

This design allows the most compact cabinet layout. Excellent availability and a long service life are achieved through the following features: A passive impedance filter per segment without active electronic components, a high‑availability fieldbus termination, and plugs with retaining screws.
