FE PETRO DISPENSER HOOK ISOLATION STP-DHI

ISOLATES DISPENSER HOOK CIRCUITSTO PREVENT ELECTRICAL FEEDBACK ASREQUIRED BY MOST ELECTRICAL CODES

FEATURES• Optically isolated inputs from up to eight dispensers

• LED’s indicate when source power is applied anddispenser hook signals are present

• Can be supplied factory wired in tandem with the FE PetroSmart Controller or our standard control box

• Compatible with any submersible pump controller

• Fuse protected output to submersible pump controller

• Retrofittable to any existing site

BENEFITS• Prevents damage to dispenser relay boards caused by cross-phasing

• Prevents electrical feedback between dispenser hook circuits during periods of maintenance and service as requiredby NEC 514-6, 1999, and other international codes

• Aids in troubleshooting dispenser hook circuits because signals are isolated

• Eliminates false STP run due to voltage leakage of multiple dispensers connected in parallel

• Small size

• Low cost
