ET-7217 Ethernet I/O Module with 2-port Ethernet Switch, 8-ch AI, 4-ch DO

The ET-7217 is a module with 8-channels of differential analog inputs and 4-channel of digital ouputs. It provides programmable input ranges on all analog channels (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA and 4 ~ 20 mA) and the digital output can be set as an alarm output with Short-circuit protection and overload protection.

Each analog channel can be configured for an individual range and has 240 Vrms high overvoltage protection. Each analog input can be programmed to accept voltage or current as an input depending upon the position of corresponding jumper. The sampling rate of ET-7217 is changeable; there are fast mode and normal modes for your consideration. The ET-7217 also has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.
