Power and communications for remote electronic devices

Abstract

An electronic device (4) for deployment in a remote location such as a well-bore comprises two main device terminals (26) for connection to a remote power supply and communication assembly (2) via two electrical couplings (6); a power storage arrangement (C1) having two power input terminals (20); a device communication arrangement (22) having two device communication terminals (24); a device switching arrangement (S2) for selectively connecting each of the two power input terminals (20) or each of the two device communication terminals (24) to a respective one of the main device terminals (26); and a device controller (28) for controlling the operation of the switching arrangement. A power supply and communication assembly (2) is also provided and arranged to be coupled to one or more of the devices (4).
