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.
Note: Each configuration also has a 240VAC international equivalent. Please call 1-800-333-3331 for more information.
