Abstract

Apparatus for supplying power to a field device, comprising: a first electrical connector adapted to electrically couple a field device to the apparatus, a power supply unit electrically coupled to the first connector and adapted to provide electrical power to a field device via the first connector; a local user input, e.g. a manually operated switch, adapted to be actuated by a user; a monitoring circuitry electrically coupled to the local user input and adapted to detect an actuation of the local user input. The monitoring circuit is adapted to generate an activation signal causing the power supply unit to provide electrical voltage to the first electrical connector for powering a field device electrically coupled to the first connector.
