DIN Rail Redundancy Module
The DIN-PWR-RD redundancy module was developed for the connection of two power supplies on a Crestron® control system such as the DIN-AP4 in order to get a perfect redundant system.
The DIN‑PWR‑RD redundancy module allows two power supplies to be connected to a Crestron® control system (such as the DIN-AP4) to achieve a redundant power system. Two power supplies are connected to the inputs of the DIN‑PWR‑RD. The DIN‑PWR‑RD output is connected to the control system. If one of the power supplies fails, the second power supply takes over to power the system to prevent downtime. Additionally, a galvanically separated relay contact, which can be connected to a digital input of the control system, will close for power supply failure reporting. Voltage indication and current consumption is indicated on the 2-line LCD display.
