Modular relay control

Sammanfattning: Enics Sweden AB, Västerås, is an electronics manufacturing services company with its main business in manufacturing electronics. Most, if not all, electronic devices that are manufactured are being widely tested before delivery to ensure proper functionality. Often during tests a large number of signals are measured by one to a few digital multimeters and are therefore controlled through relays. Relays are also used when applying stimuli with high currents or voltages to the unit under test. This work have been focused on finding a concept, including designing and producing a prototype, for a modular relay control system for use in fabrication of small test systems and for use when there is a need for adding more relays to an existing system.
