Modular Relay Board

Alliance Support Partners, Inc. (ASP)

An increasing number of electronics products are being assembled in panels of 8 or more to minimize production cost. These products are typically tested with in-circuit tests (ICT) followed by power-on functional tests. Normally, ICT requires isolation of power and ground while measurements are being performed. Functional tests, including in-system programming (ISP), require board power to be applied. The Modular Relay Board (MRB) is designed to switch power onto each individual board and to disconnect sensitive signals during functional test.
