Industrial rs-1p-mb-03 Relay Control Board Assembly

Industrial RS-1P-MB-03 Relay Control Board Assembly from Royal Service is a dedicated relay board designed for use in automation panels and control enclosures. The Rev. A RS-1P-MB-03 variant is commonly described in listings as a Royal Service component paired with an LCD Concepts interface, indicating an LCD display/interaction feature that supports monitoring and control within a single mounting assembly. This relay control board provides discrete outputs to switch external circuits, enabling straightforward integration with a host controller, PLC, or microcontroller in industrial environments. Typical applications include panel-mounted control of pumps, indicators, alarms, and other devices requiring reliable relay actuation, with listings sometimes noting suitability for marine and industrial contexts. The model name, RS-1P-MB-03, and its Rev. A designation identify this specific revision of the board within the Royal Service lineup, helping buyers confirm compatibility with existing control panels or replacement parts. In practice, this board serves as the central relay-driving module in a compact form factor, enabling engineers to route control signals to multiple relays from a single assembly, streamline wiring, and reduce panel footprint.
