3000 VDC Channel-to-Channel Isolation M-2217CI-4: 4-channel differential analog inputs M-2217CI: 8-channel differential analog inputs Current, Voltage Input 120 VDC Overvoltage Protection Resolution: 12/16 bits Adjustable Sampling Rate Wide Operating Temperature Range: -25 ~ 75°C

Model: M-2217CI-4

Model: M-2217CI

The M-2217CI is a Channel to Channel Isolation analog input module that includes 8 differential analog input channels and provides a programmable input range on all analog inputs (±1 V, ±2.5 V, ±5 V, ±10 V, ±20 mA). It provides a high overvoltage protection of 120 VDC. The sampling rate of the M-2217CI is adjustable and is available in either fast or normal mode and It also provides 4 KV ESD protection as well as 3750 VDC intra-module isolation.
The M-2217CI-4 has the same specifi cations as the M-2217CI, but provides 4 differential analog input channels.
