Description
Relay PC Board 280295-001 1602-0400 Rev A 4-Relay DIN Rail DB25 Fill/Run Ctrl
This is a multi-relay PC board assembly (part number 280295-001) built around a green DIN rail-mount housing. The PCB itself is marked P/N 1602-0400 Rev A and carries four relay positions populated with relay components. The board interfaces to a host system via a DB25 (D-Sub 25-pin) connector and provides multiple screw terminal blocks along its perimeter for field wiring. A toggle switch on the board selects between FILL and RUN operating modes, and red LED indicators provide status feedback.

Applications
Relay PC boards of this type are used in industrial process control and automated dispensing or fluid management systems, where a centralized relay card switches multiple output loads under direction from a host controller or PLC communicating over a parallel interface like DB25. The FILL/RUN mode toggle is characteristic of liquid-level or fluid dispensing control systems — FILL mode typically initializes or pre-charges a system, while RUN mode transitions it to normal operating logic. These boards are commonly found in automated filling equipment, industrial process controllers, and similar systems where multiple relay outputs need to be driven from a single interface connector. The DIN rail housing allows the board to mount directly inside a control cabinet on standard 35 mm DIN rail.
