Detailed data
ABB SCYC55870 Power Voting Unit
The ABB SCYC55870 Power Voting Unit is part of ABB industrial automation and control systems and is used in critical systems that require high availability and reliability. Power Voting Units are used in redundant systems to ensure that the system continues to operate even if one or more components of the system fail. The SCYC55870 may be part of a larger control system.
The Power Voting Unit manages and monitors redundant power supplies in a system. In critical control systems, redundancy is key to preventing failures. The voting unit ensures that the system selects the correct power supply if one of the power supplies fails. The unit ensures that the system continues to operate without interruption, even in the event of a hardware failure.
In the context of redundancy, a voting mechanism typically determines which one is operating properly by comparing inputs.
If there are two or more power supplies supplying power to the system, the voting unit "votes" to determine which power supply is providing the correct or primary power. This ensures that the PLC or other control system can operate normally even if one of the power supplies fails.
The SCYC55870 Power Voting Unit improves the high availability of critical systems by ensuring that the control system does not stop operating due to the failure of a single power supply.
Frequently asked questions about the product are as follows:
-How does the voting system work?
The unit constantly monitors the power supplies to ensure that the system has available power. If one power supply fails or becomes unreliable, the voting unit will switch to another functioning power supply to keep the system running.
-Can the SCYC55870 be used in a non-redundant system?
The SCYC55870 is designed for redundant systems, so it is neither necessary nor economical to use it in a non-redundant setup.
-What happens if both power supplies fail?
In most configurations, if both power supplies fail, the system will shut down safely or enter a fail-safe mode.
