The Red Jacket® ISOTROL™ 1-8 Control Box is the most versatile dispenser handle signal isolation system available. It provides a means to remove all external voltage sources, including feedback, during periods of maintenance and service of the dispensing equipment to meet NEC requirements.
The Red Jacket® ISOTROL™ 1-8 Control Box isolates handle signals between each dispenser and protects against wiring shorts and phasing issues. It is available with or without a built-in 30-amp 2HP rated relay.
ISOTROL™ 1-8 units without the relay are designed for use with the TLS-450PLUS or another component for motor control – IQ, standard control box or three phase magnetic starter and will accept up to eight individual dispenser signals.
ISOTROL™ 1-8R units with the relay bypass an ATG to activate one pump and will accept up to eight individual dispenser signals. They can also be utilized to activate a second pump in manifolded applications.
Each configuration also has a 240VAC international equivalent – ISOTROL™ 1-8-i and ISOTROL™ 1-8Ri. Please contact customer service for more information.
The ISOTROL™ 1-8 provides electrical isolation between the dispenser pump enable signal and the submersible turbine pump control relay. Other energized sources of power can still exist within the dispenser even with this device installed. You should always verify that all sources of power are disconnected before servicing a dispenser. Always follow proper Lockout/Tagout procedures when servicing electrical equipment.
At any time the enclosure must be opened during a troubleshooting procedure, disconnect controller power prior to removal of the cover. This includes the dispenser signal outputs that are powered from separate circuits in the system.
