The Triconex 3704E is a high-density Triple Modular Redundant (TMR) Analog Input Module. Designed for versatile signal acquisition, it features 64 single-ended input points capable of handling both 0-5V/0-10V voltage and 0-20mA current inputs. Distinguished by its Copper color code, the 3704E offers programmable current ranges via shunt resistors and robust overrange protection for reliable operation in industrial environments.
