By Rust at 21 February, 2010, 5:17 am
The benefits of 4-20mA current loop format in process control systems are 2-wire sensor operation, long cable runs, and noise immunity. The voltages for the loop can be ranging from 12VDC to 40VDC and are inherently nonratiometric to the output signal. The MAX1452 low current consumption allows the system to operate from loop power with [...]
