Digit Backlit LCD Voltmeter Module – IC-SP 400-EB

The SP 400-EB features an enhanced black LCD and 200mV d.c. measurement range with auto-zero and auto-polarity and seven different colour options for the backlight. Decimal points are user selectable.

The SP 400-EB features a negative rail generator which enables the meter to measure a signal referenced to its own power supply GND. Enhanced contrast negative mode LCD with white LED backlighting ensures excellent readability under all light conditions.

The module is easily fitted into the panel, using the fixing clip provided. The module’s low cost means it will suit high and low volume applications. The design of the panel meter’s housing ensures splash proofing using the supplied seal.

The SP 400-EB backlighting is available in seven different options. These include white, red, orange, magenta, yellow, green and blue.
