Designed for installation on DINrails, the FPH integrates fieldbus segment connections, appropriate terminators, and host-specific system connectors. The hub follows the passive design of powering the fieldbus network and provides redundant galvanic isolation and host spur protection. Cross-talk resonance suppression ensures proper communication, particularly in the event of wiring and ground faults. Multiple plug-on modules available include an isolated power module with 30 V at 500 mA., an isolated FNICO power module with 17 V and 500-mA rating, and nonisolated modules with host spur protection.
