The I-7017 and I-7017F are analog input modules that provide either 8 differential input channels, or 6 differential input channels and 2 singleended input channels selectable via a jumper. The input type includes both voltage and current, and all channels are available for the same input range. An optional external 125 Ω resistor is required for current input. The modules also feature 3000 VDC intra-module isolation as well as +/-120 VDC overvoltage protection. The sampling rate of the I-7017F is adjustable, meaning that either fast mode or normal mode can be selected. The M-7017 supports both the Modbus RTU and DCON protocols, which can be configured via software, and provides 8 differential analog input channels. Other hardware specifications are the same as the I-7017.
