STP-DHIB DISPENSER
HOOK ISOLATION
The FE PETRO® dispenser hook isolation device prevents
electrical feedback between dispenser hook circuits as
required by most electrical codes.
HIGHLIGHTS
• Optically isolates inputs from up to eight dispensers
preventing damage to dispenser relay boards caused by
cross-phasing.
• Prevents electrical feedback between dispenser hook
circuits during periods of maintenance and service as
required by NEC 514-3, 2002 and other international codes.
• Can be supplied factory-wired in tandem with the FE
PETRO® smart controller or the FE PETRO® standard
control box.
• Eliminates false STP run due to voltage leakage of multiple
dispensers connected in parallel.
• Fuse-protected output to submersible pump controller.
• The STP-DHIB can retrofit to any existing site.
