| | 1, Dynamic input: A1, A2, A3, A4 corresponds to four channels of dynamic signal input, the highest sampling rate of 128kSPS, each channel wiring is the same, the left figure is the A1 channel wiring diagram, the factory default is to be connected to the IEPE sensor, if you need to be connected to the voltage / 4-20mA type sensors, need to be specified when ordering. Each channel's pin 1 can provide 24V power supply for external sensors, maximum 50mA current, if external sensors need to use the 1-pin power supply, please pay attention to check the wiring to avoid damage caused by the wrong line. | |
| 2,Analog input: B1, B2, B3, B4 correspond to 4 channels of slow variable analog signal input, each channel wiring is the same, the following figure is the B1 channel wiring diagram, the factory default is to be connected to the voltage input sensor, if you need to be connected to the 4-20mA type sensors, need to be specified when ordering. Each channel's pin 1 can provide 24V power for external sensors, maximum 50mA current, if the external sensors need to use the 1-pin power supply, please pay attention to check the wiring to avoid damage caused by the wrong line. | | |
