JEOL SP000300-01 Printed Circuit Board Card Assembly is a six-switch, replaceable circuit board designed for JEOL instrumentation. Also associated with SP000308-01, this modular PCB provides the switch-based interface required by compatible JEOL systems. As a card assembly, it integrates into the instrument’s control circuitry to substitute the corresponding SP000300-01 module and support continued operation with JEOL equipment.
