The Allen Bradley 1606-XLBUFFER serves as a dedicated buffer unit within the 1606 series for switched mode power supplies. It is built to achieve a nominal voltage rating of 24 VDC, accommodating a voltage operational range from 24 to 28.8 VDC. Input voltage levels are ideally maintained, with adjustable buffered voltage limits set between 23 and 27.8V, alongside a fixed threshold option at 22.5V to suit various applications.

For charging, this unit draws current of less than 600mA and can output a buffering current ranging from 0 to 20 Amps, effectively catering to dynamic load requirements. During buffer operation, it can handle current limitations greater than 20 Amps, affirming its robustness under load. The charging process requires 18 to 27 seconds, ensuring efficient energy management. Typical performance shows an idling input current of roughly 80mA, and its power dissipation is rated at about 1.9W, which is efficient for its class.

With an IP20 rating, the 1606-XLBUFFER is designed to offer basic protection from solid objects, making it suitable for a comfortable installation environment. Notably, this buffer unit does not have internal fusing, which simplifies its design. Additionally, it provides galvanic isolation of 500 volts to signal paths, alongside a high isolation resistance of 5MOhm in the terminal housing, ensuring safety and stability during operation.
