PHL-T24-L4-EX
The following features describe this intrinsic safety surge prevention device for 24 volt systems:
12.4 mm very thin design The design is incredibly space-efficient, making it ideal for locations with limited room. It is also simple to install in control cabinets or other equipment.
Because the surge protection module is hot swappable, operating safety and convenience are increased because there is no need to shut down the system when performing maintenance or replacing the protection module.
Single-use detection: The surge protection module can be tested independently, which facilitates the prompt identification and resolution of issues and guarantees the system's continuing operation.
Applicable to a wide range of signal circuits: offers efficient surge protection for a wide range of signal circuits, including RS232, DI, DO, AO, and AI (analog input, digital output).
Grounding using a metal DIN35 guide rail: Enhancing the stability and safety of the system is possible by grounding through a metal guide rail, which guarantees the dependability of equipment grounding.
