Frequently Asked Questions

How does the UR9VM CPU module integrate with existing substation automation systems?
The UR9VM provides native IEC 61850 MMS and GOOSE messaging for modern substation automation, while maintaining backward compatibility with DNP3 and Modbus protocols for legacy SCADA integration. Multiple Ethernet ports allow simultaneous connection to station bus and process bus networks without external gateways.

What is the maximum number of I/O points the UR9VM can manage in a single chassis?
The CPU module supports up to 64 digital inputs, 32 digital outputs, and 16 analog inputs when fully populated with expansion modules. This capacity handles complex protection schemes including transformer differential, bus protection, and breaker failure applications in a single relay platform.

Can the UR9VM operate in redundant configurations for critical protection applications?
Yes, dual UR9VM modules operate in hot-standby redundancy with automatic failover in under 50ms. The redundant configuration shares I/O modules and communication interfaces, with synchronized settings and event records to ensure seamless transition during primary module failure or maintenance.
