Multi-Channel Power & Relay Board

A multi-channel power distribution board with relays and high-side MOSFET switching.

Multi-Channel Power & Relay Board

About this board.

Tall-format power-control PCB built around a bank of high-side MOSFETs and a pair of blue mechanical relays. A large electrolytic on the input rail handles bulk decoupling, and the central area is reserved for cleanly routed switching paths between the regulator stage and the output stage. Screw-terminal outputs at both ends make field wiring straightforward.
