KSA-1100 Isolated Distributor
The KSA-1100 isolated distributor achieves three terminal isolation of power supply, input, and output. Filter and attenuate the on-site two-wire signal, three wire signal, and four wire signal (active signal), block the ground loop, isolate different ground potentials, suppress the influence of external magnetic fields, and generate standard analog signals. The product with HART function realizes bidirectional transmission of digital communication overlaid on analog signals.
