SSD7500 TACH and RPM Readout.

Description

The SSD7500 is a direct replacement for the legacy  readout found on many panels.

Features:
– Simultaneous Indicating of RPM and DEG
– Accurate Measurement of Ignition Timing
– Precise Digital Readout of Engine Timing Degrees
– Accurate Tachometer
– Sensor Failure Indication
The Digital Timing Indicator give a numerical readout of the ignition system timing point in degrees
before or after top dead center.
Input signals are from no.1 cylinder and a magnetic pickup to sense a top dead center reference.
The RPM and DEG values are displayed simultaneously on a backlighted LCD display.
