Frequently Asked Questions about UR-8LH
A UR-8LH is a CT/VT module (current transformer and voltage transformer) found within some of the universal relays. Each universal relay contains a CT/VT module, a CPU, a power supply, an IEC Process Bus, inter-relay communications, a communication switch, a digital I/O, and a transducer I/O. The CT/VT module can include up to 24 signals for the monitoring function of the AC power lines. Some CT/VT modules even have sensitive ground input for the purpose of ground fault protection. If this is the case, the order code designation will afford the unit this feature. The Multilin UR-8LH has order specifications that include the standard 4CT/4VT characteristic but with enhanced diagnostic features. The 8G, 8J, 8M, and 8R CT/VT modules are the ones with the sensitive ground fault protection capability. The UR-8LH is a new module CT/VT, thus it should be paired with a new CPU to avoid a hardware mismatch error. Firmware versions of at least 4.0x are compatible with the new CPUs and the new CT/VT modules. In comparison, the universal relay will need the firmware version of 3.4x or previous firmware versions in order to be compatible with the older CPUs and CT/VT modules.
