Analog Input Current Input Module 8AI

CT 3238 Analog Input Current Input Module 8AI The CT-3238 8-channel current analog input module by Sichuan Odot is engineered for high-density, mission-critical data acquisition in global industrial systems, directly addressing pain points such as high per-channel cost, signal crosstalk, surge vulnerability, and complex sensor powering. It supports 8 independent channels configurable for 0–20mA or 4–20mA current inputs—fully compatible with standard industrial transmitters—and accepts both 2-wire sensors (requiring external loop power) and 4-wire active current-output sensors, offering maximum field flexibility. A key differentiator is its magnetic insulation between the internal backplane bus and field inputs, providing complete galvanic isolation to eliminate ground loops and ensure signal integrity over long cable runs. Each channel interfaces directly with active analog current-output sensors and features built-in TVS overvoltage protection, safeguarding against lightning strike…
