The CUB4L8 is an 8-digit counter with a digit height of 12 mm. It is available with standard LCD (operation without external power supply possible) or backlit LCD display. In the latter case, the digits light up intensely red or green-yellow. Pulse detection is performed by a highly integrated CMOS counter chip. For devices with backlighting, the required supply voltage can be provided via 9 VDC to 28 VDC or a screw-on power supply unit (see accessories).
