Abstract

A pluggable electrical unit with module electronics has a bus access unit for electrical connection of the pluggable unit to an electrical base unit. The base unit comprises a power supply, a signal processing means and signal lines for identification, control lines, address lines and data lines, which are connected in the manner of a bus to a plurality of contact devices. The bus access unit has a variable resistor and switches for isolation. The variable resistor and the switches for isolating signal lines for identification, control lines address lines and data lines in the pluggable electrical unit are linked to one another in a causal chain.
