Description

The Bus Interface Unit Protector (BIUP) is a three terminal device specifically designed to protect the signal inputs to the bus interface unit devices. The surge protector offers protection in the common mode (line to ground) and differential mode (line to line). The two outside terminals (labeled DL) are for the data lines, while the center terminal (labeled G) is designated for the ground.

Specially selected solid state clamping elements have been chosen for the electrical design of the BIUP. These elements have been arranged in such a manner as to appear virtually invisible to the bus interface unit, while offering the maximum surge protection available on the market today.

The BIUP also incorporates resettable fuses for each data line (DL). These fuses appear as high impedance components during a transient situation and return to a low impedance state once the surge has been eliminated. Not only do these resettable fuses add further protection to the bus interface units, they prolong the life and integrity of the surge protector.
