Description
The Phoenix Contact UTTB 2,5-2DIO/O-UL/O-UR, item number 3046689, is a diode component terminal block designed for electrical control panels and industrial automation installations. It combines terminal connections with an integrated diode, allowing the component to be incorporated into suitable control and signal circuits.
Its two-level construction provides four connections across two potentials, while the 5.2 mm width helps conserve space on DIN rails. Screw-clamp connections provide a secure method of connecting compatible conductors.
