The I-87017ZW is an analog input module that includes 10 differential or 20 single-ended analog input channels. It provides a programmable input range on each analog input (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V,+/-10 V, +/-20 mA, 4 ~ 20 mA or 0 ~ 20 mA). Each analog input can be configured for an individual range that provides 240 Vrms over voltage protection and 50mA over current protection at 110VDC/VAC. Voltage and current inputs are jumper selectable. The sampling rate of the I-87017ZW is adjustable and is available in either fast or normal mode. The module features 4 ~ 20 mA open wire detection for each channel, and provides 4 KV ESD protection as well as 3000 VDC intra-module isolation.
