The Termination Board is designed to support various signal types in hazardous environments. It accommodates up to 8 modules and operates on a 24 V DC supply.
The Termination Board is an essential component within the Pepperl+Fuchs intrinsic safety barriers category, facilitating safe and efficient signal management in hazardous areas. This product enables the connection of various signal types, including Digital Inputs (DI), Digital Outputs (DO), Analog Inputs (AI), Temperature Inputs (TI), and Analog Outputs (AO), ensuring compatibility with a wide range of applications.
Engineered for environments where safety is paramount, the Termination Board features distinct screw terminals for both hazardous and safe areas, with blue terminals designated for hazardous zones and black terminals for safe areas. This ensures proper isolation and protection while providing reliable connectivity for field devices in industries such as oil and gas, chemical processing, and other sectors where explosive atmospheres may be present.
