Bosch PRD 0004 A 4-Module Large Panel Rail

This is an extended mounting rail manufactured for panel layouts that can be expanded up to four modules. Modules mounted on it operate with 5–24 VDC power supply without requiring additional wiring; the plastic housing is designed for a temperature range of -5 to 50 °C. The anthracite gray color RAL 7016 creates visual consistency with other components in the same cabinet. Since spare controller and keypad cables connect directly to this extended rail, the redundant structure does not require intermediate terminal blocks.
