PK40 Series Multi Channel Signal IsolatorDetailed product description：

Scope of application
The PK40 series signal isolator is used for adjusting and isolating various signals of field instruments, and converting them into standard signals that can be accepted by computers, DCS, PLCs, or special signals specified by users. This isolator has multiple signal inputs and corresponding multiple isolated signal outputs Input, output, and power supply are fully isolated Strong anti-interference ability, high precision, and rail installation. It has extremely high cost-effectiveness, reliable and stable operation, and can be matched with unit combination instruments and DCS, PLC and other systems. It has a wide range of applications in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.
