KSA-1200 isolator
The KSA-1200 isolator achieves three terminal isolation of power supply, input, and output. Filter and attenuate on-site current or voltage signals, block ground loops, isolate different ground potentials, suppress the influence of external magnetic fields, and generate standardized analog signals.
