Terminal Block Interface Modules

Terminal Block Interface Modules are modular wiring interface devices that sit between field wiring (sensors, actuators, power lines) and control equipment (like PLCs, I/O cards, relays, or controllers). Their job is to organize, protect, and simplify electrical connections while often adding signal conditioning or isolation.

Terminal block interface modules are available from Mouser from industry leading manufacturers including Advantech, Eaton, Murrelektronik, Phoenix Contact, Weidmueller & more. Please view our selection of terminal block interface modules below.
