GE Multilin UR6AV is a digital input/output (I/O) module specifically designed for the UR Series protection and control relays. Its core function is to expand the digital input/output capabilities of this relay series, so as to meet the needs of signal monitoring and equipment control in industrial scenarios, and it is often used in fields such as power systems and industrial control.

Core Interfaces and Functions

Digital Inputs

Equipped with 8 digital input channels, it can be used to monitor signals from external devices and capture various event statuses in industrial sites. It provides the system with accurate data on the external environment and equipment operation, serving as the basic data source for implementing protection and control logic.

Digital Outputs

Output types include Type A (normally open contacts) and Type C (changeover contacts), with variations across different configuration versions.

• The version with order code 6A includes 2 Type A outputs with voltage monitoring (optional current monitoring) and 2 Type C outputs.
• The version with order code 6V includes 2 Type A outputs with optional voltage monitoring, 1 Type C output, and 2 outputs with latching function.

The activation speed of Type A outputs is less than 4 milliseconds, meeting the fast-response requirements of dry and wet contact scenarios. It can also be equipped with circuit detection function as needed.

Key Technical Specifications

Typical Applications and Advantages

• Core Application Scenarios: Often used in the integration of relay protection systems, it can work with various relay protection devices to build a complete protection solution. It is also suitable for the transformation and upgrading of existing electrical equipment, adding precise monitoring and control functions to old equipment. The UR Series it adapts to is widely used in fields such as power transmission and distribution, and industrial automation production lines, so this module also widely serves the equipment linkage control in these fields.
• Core Usage Advantages: The modular plug-and-play design not only simplifies the installation process but also facilitates later maintenance and component replacement. It can realize partial latching functions without additional latching relays, reducing system accessory costs. At the same time, the 12-month original factory warranty service can also reduce the usage risks of industrial users.
