1、 Frequency signal isolator:

The YSD-F frequency signal isolator type converts sine wave and rectangular wave pulse frequency signals into standard analog signal outputs or relay contact signal outputs through isolation. It can be directly connected to digital displays, PLCs, and computer systems. This product is widely used in automatic cargo systems in the mechanical, electrical, railway, petrochemical, metallurgical, chemical, food, and wastewater treatment industries.
