Shenzhen battery voltage logger, multiple battery recorder, multi-channel voltage logger

1, the signal type 1) Voltage signal: 0-10VDC, a total of six inputs. 2) measuring the start and stop signals: the external control switch contact, passive, a total of six inputs. 3) failure signal: OC door, a total of 12 outputs. 2, wiring list of large ones measuring voltage signal input terminal number from idling stop input terminal number output terminal number unqualified failure load output terminal number of the first channel 2 (+) and 3 (-) 20, 21 49, 50 51, 52 second path 5 (+), 6 (-) 23, 24 53, 54 55, 56 a third channel 8 (+), 9 (-) 11 26, 27 57, 58 59, 60 a fourth channel (+) , 12 (-) 14 29, 30 61, 62 63, 64, a fifth path (+), 15 (-) 32, 33 65, 66 67, 68 17 Sixth Road (+), 18 (-) 35, 36 69, 70, 71, 72 Second, the testing process 1,6 loops are controlled independently. 2. Display: The LCD display is divided into six regions, are shown from 1 to 6 control loops, need to show the status (idle, load, load), measured, timed (standby display 0, 0 is displayed when idling, After starting from zero load access time, after the set test time timing is stopped), and qualified unqualified status. 3, the first road, for example, the control process as follows: 1) when the recorder power, "measurement start and stop input" If in the off state, then the recorder only displays the first measurement value, "Measuring start-stop input "closed, then start the test. 2) After the detection start, battery load, if the measured value at this time is smaller than the set "zero limit 1" (one for each control loop has a "zero limits" set point, namely the "zero limit 1" ... .. "Zero Limit 6") of the set value, the direct output "load fail", "Load failure" signal, said that "no-load voltage" a "load last voltage" are unqualified. Simultaneous recording of this test data, including control circuit (01 to 06), this test number (at this time of year, month, day, hour, 12 figures), this test load voltage (= 0), the maximum load voltage (= 0), and finally the load voltage (= 0), the timer set time (= 0). When the "start and stop measuring input" After disconnecting, disconnect the recorder output "load fail", "Load failure" signal the end of this test.
