Product Overview:
The WJ17 series four wire milliohm resistance signal isolation amplifier is a type of amplifier that isolates, amplifies, and converts small resistance signals into proportional output DC
Signal rail installation and transmission module. The product is widely used in machine equipment, connector production lines, mechanical relay production lines, instruments and meters, and medical equipment
Industries such as equipment and industrial automation. This series of modules is embedded with an efficient low-power power supply, providing isolated power supply to the input and output terminals
A photoelectric coupling isolation amplifier with analog signal output, using a four wire measurement method for input resistance, eliminating resistance errors caused by measuring wires
Poor, the product integrates a high load capacity reference current source output internally, which is used to provide measurement current for the measured resistance. Due to internal procurement
Compared to electromagnetic isolation, linear optoelectronic isolation technology has better resistance to EMC interference and spatial electromagnetic interference.
