Data Acquisition



The M-2217CI is an 8-channel analog differential input module with 3000 VDC channel-to-channel Isolation. It provides a programmable input range on all analog input channels (±1 V, ±2.5 V, ±5 V, ±10 V, ±20 mA) also high overvoltage protection of 120 VDC. The sampling rate of the M-2217CI is adjustable and is available in either fast or normal mode. It also provides 4 kV ESD protection and 3750 VDC intra-module isolation.
