Introducing the Hummingbird Idle Timer (HMLI003)

Hummingbird Electronics' Idle Timer keeps an engine running for a pre-specified period after the ignition has been turned to the off position allowing the engine and its turbocharger to cool down, avoiding premature turbo wear and failure, and saving you money on costly repairs or replacements.

The timer is settable, and lockable putting you in control and it has an override switch in the event that an immediate engine shut down is required.


Powerful Performance

The Idle Timer is designed for a quick and easy installation with the ignition input and output wire connected directly in series with the vehicle’s ignition supply.

Idle time can be set between 1 and 5 minutes using 4 dip-switches that can be found under the lid of the device.

An optional override input allows an operator to bypass the cool-down period and instantly turn the engine off. A key-off output signal is available for auxiliary power functions. An LED output allows for a visual indication for the operator. When the ignition is turned off, the LED will flash indicating the idle time in minutes and will then stay on for the idle time.



Designed for harsh automotive environments, the module features transient voltage protection on the supply and short circuit protection. The Idle Timing module is suitable for use in both 12V and 24V vehicles. It is supplied in a rugged aluminium enclosure with provision for screw mounting when required, and a red LED inside is provided to give the user status information.
