The TB-4 is a two-piece assembly consisting of a sturdy bin for containing the modules and a removable heavy duty power supply that is mounted on the back of the bin. DC voltages available to power installed modules are: ±6 V, ±12 V, ±24 V. AC 117 V power for modules that may require it is also provided. The supply conforms to the specifications of AEC report TID-20893 (Rev. 3). The bin is constructed with nickel plated high strength top and bottom welded wire frame assemblies that ensure easy installation, accurate fit and free ventilation of the modules. The TB-4 fits a standard nineteen-inch relay rack or it can be used as the container of a compact system at the bench. A narrow panel on the front has the master power switch, test jacks for the six DC voltages and an overheat warning lamp. BNC-blue painted blank panels are available to cover unused module cavities. The part numbers are: Single-width P/N 6823, Double-width P/N 6824, Triple-width P/N 6826. Empty modules in various standard sizes are also available for those who wish to build and install their own special or auxiliary instrumentation in convenient plug-in form.
