Lingenfelter RPM Activated Window Switch

The Lingenfelter Performance Engineering RPM-002 RPM Controlled Switch incorporates a precision 32-bit timer to realize microsecond precision over a very wide operating RPM range. Most common tachometer pulse frequencies are supported with no additional components required.

Features
· RPM switch settings can be adjusted in 100 RPM increments from 500 to 19900 RPM.

· Accepts both traditional 12 volt tachometer signals and also accepts 5 volt reference engine speed signals found on many newer cars, trucks and motorcycles.

· Fully encapsulated (potted) construction for increased durability.
· Rated for operation at up to 185 degrees F (85 degrees C).

· Outputs rated for up to 2.0 amps. For higher current levels, the switch should control a relay.

· Both the normally on and the normally off outputs can be used simultaneously.

· The RPM-002 can perform as a standard RPM activated switch or it can provide “Window” switch type capability, switching at one RPM level and then switching back at a second RPM level.

· When operated in standard RPM activated switch mode, the RPM-002 can be a shift light controller. As a shift light controller, the RPM-001 should be able to trigger most common 12 volt shift lights. For shift lights that draw more than 2.0 amps, a relay would need to control the light.

· Outputs have a self protect feature and will turn OFF in case of a direct short or over current condition.

· Operating voltage range: 9.0 to 16.0 volts.

· Input signal type: +12 volt DC square wave or coil negative terminal and +5 volt DC reference signal applications.

· Input signal impedance: 10k ohms.

· Current draw: 0.1 amp plus current draw of device being controlled (when active).

· 90 day warranty from date of purchase
