    3.3 Analog Input Connections The differential input channels operate with two signal wires for each channel, and the voltage difference between both signal wires is mea- sured. There are 8 analog input channels available on USB-4718 Figure 3.2: Differential Input Channel Connection 3.4 Isolated Digital Input Connections USB-4718 has 8 isolated digital input channels designated IDI0~IDI7.

  • Page 36: Isolated Digital Output Connections

    If an external voltage (5 ~ 30 VDC) is applied to an isolated output channel while it is being used as an output channel, the current will flow from the external voltage source to the card. Please take care that the current through each IDO pin not exceed 200 mA. USB-4718 User Manual...
