Abstract

A terminal block assembly comprising terminals in combination with associated signal indicators is disclosed. The assembly includes one or more rows of terminals and, associated with each row of terminals, a row of signal indicators. The signal indicator typically is a light emitting diode. Each indicator is located in proximity to one or a few terminals, to which it may be connected electrically. Each signal indicator displays the operational status of a load module connected to a terminal on the terminal block assembly. Operational status may include fault detection, output signal, input signalling, or the like. The placement of the signal indicator immediately adjacent to its respective terminal simplifies and speeds up identification and eliminates any question of improper identification of the load modules connected to the terminal blocks.
