Module 2 cổng Ethernet Modbus TCP 8 kênh đầu vào tương tự AI + 4 kênh đầu ra số DO ICP DAS ET-7217 CR

The ET-7217 is a module with 8-channel differential analog inputs and 4-channel digital ouputs. It provides programmable input range on all analog channels (+/-150 mV, +/-500 mV, +/-1 V, +/-5 V, +/-10 V, +/-20 mA, 0 ~ 20 mA and 4 ~ 20 mA) and digital output can be set alarm output with Short-circuit protection and overload protection. Each analog channel is allowed to configure an individual range and has 240 Vrms high overvoltage protection. Each analog input can be programmed to accept voltage or current as input depending upon the position of corresponding jumper. The sampling rate of ET-7217 is changeable; there are fast mode and normal mode for your consideration. ET-7217 also has qualification for 4 kV ESD protection as well as 2500 VDC intra-module isolation.
