2.2.2. Supply Input

• Single DC Power Supply: Power to the Gold Bell is provided by a single 12 V to 95 V isolated

DC power source (not included with the Gold Bell). A “smart” control-supply algorithm

enables the Gold Bell to operate with only one power supply with no need for an auxiliary

power supply for the logic.

• Optional Backup Supply: If backup functionality is required in case of power loss, e.g., to

keep the original position, an external 12 V to 95 V isolated supply should be connected.

This is more flexible than the requirement for 24 VDC supply.

If backup is not needed, a single power supply is used for both the power and logic circuits.

There are multiple voltage ratings of the Gold Bell (12 V to 95 V), so you must use the correct

power supply according to the maximum operating voltage of the Gold Bell. See Section

Chapter 3: Technical Information.
