Big boy battery isolator relay full#

The Isolator Relays are ignition protected, so they can safely be mounted in a convenient place near the battery.

These relays, with their heavy construction, can easily deliver the needed current.

In a jump start environment, the relay may have to deliver the full starting current of the engine. To be sure these relays can perform under these harsh conditions, the contacts are protected with a unique antioxidant coating. The relay's contacts must close and provide a low resistance without the benefit of any arcing for cleaning. At that time, there is no voltage across the contacts. In a battery charging situation, both batteries may be fully charged and at equal voltages. A momentary, dash-mounted switch can also be added to provide a 'jump start' for the engine, from the auxiliary battery. The 200 amp version is not a continuous duty unit and requires an Intellitec Isolator - diesel controller to prevent it from overheating when it is used for continuous duty. The 100 amp unit can be switched manually through a dash-mounted switch or coupled with one of Intellitec's Isolator controls for fully automatic functioning. It is installed between the two batteries, connecting them together for charging. The Isolator Relay provides a simple, reliable, and cost effective means of isolating two battery systems. The 100 amp Isolator Relay is designed for most common gasoline engines, while the 200 amp Isolator Relay is designed for heavier duty applications. These relays have been designed and are built to meet these demanding conditions. In this application, these relays are required to operate with almost no voltage across their contacts and carry currents ranging from milliamps to hundreds of amps. Intellitec.s Isolator Relays are specifically designed to be used to isolate two battery systems.

Specifications: Relay Actuation Voltage 10.5 Volts Continuous Carry Current 100 Amps max. The fuse on the left feeds the power to the switch that operates the solenoid. Looking at the relay with cap at the top, the fuse on the right feeds the LED indicator and if so equipped, the digital voltmeter. FUSES There are two 5 Amp fuses for the system, mounted on each relay. When the voltage is removed from the coil, the plunger gets pushed upwards by the return spring, breaking the connection between the two large terminals. However, since the magnetic polarity of the coil is reversed, the rod is repelled (like poles oppose), and swings out of the way. When this is done, the plunger is again pulled into the coil. To open the relay, +12 volts is applied to the “S” terminal and ground on the “I” terminal. When the voltage is removed from the coil, the plunger gets pushed upward by the return spring, but cannot move because the rod magnet is in the way. While this happens, the rod magnet suspended above the plunger is attracted (opposite poles attract) to the top of the plunger by the magnetic field. When this is done, the plunger is pulled into the coil and the contacts are connected. To close the relay, +12 volts is applied to the “I” terminal and ground the “S” terminal of the relay. THE RELAY – How it Works The Battery Disconnect Relay is a mechanically latching switch that operates by the momentary application of battery voltage to the coil terminals in one direction for latching (closed) or the other direction for unlatching (open). The relay is sealed against the environments and is designed to withstand the shock and vibration experienced in the most severe RV or boat applications. While this relay is capable of carrying heavy currents, it requires NO power to stay open or closed. The heart of the system is a unique latching relay developed specifically for this purpose. With a touch of a remote switch, the batteries will be completely disconnected, preventing unwanted drain when the RV or boat are put into storage. Intellitec Battery Disconnect Relay 01-00055-000īattery Disconnect Relay Battery Disconnect provides a simple and safe means of remotely disconnecting batteries of an RV or boat.
