Specification:Working voltage: DC 7-12V/100mALight color: 7 * green+2 * orange+3 * redSize: approximately 79 * 14 * 8mm/3.11 * 0.55 * 0.31 inchImportant note:1. MCU in the sampling time-sampling, so that there is dual-channel simultaneous parallel input signal changes fast, the amplitude of the two light bar display may vary, this is a normal situation.2. In extreme cases, there may be very slight high frequency noise. Recommended to replace the signal input line head position as dual-core shielded cable.3. Operating voltage: 7-12v current can work in more than 100MA. Prohibited or voltage exceeds 12v positive and negative reversed, whether the person will cause light damage level Display effect:1. strip show+ after peak travel whereabouts2.  strip show after+ the disappearance of the peak travel3.
