2024-12-31 BY jonson

UR8HH|1A/5A ground CT and 3-1A/5A phase CT are available for relays

General Electric Multilin’s UR-8HH is a CT/VT module designed to be installed in the general purpose relay family. It provides the relay with 1A/5A ground CT and 3-1A/5A phase CT, which allows the relay to narrow the rated current and rated voltage to a single value, enabling the relay to monitor these system conditions and output data for the user to view. This data can then be used for protection system functions performed by the relays themselves. This data can be viewed via the relay’s LCD display or more efficiently via Multilin’s EnerVista UR software program.

EnerVista UR also allows for efficient configuration of the Settings associated with CT/VT modules, allowing for highly customized schemes to meet the unique needs of each user’s system. In addition, EnerVista UR’s simplified design enables users to easily view data in a beautiful, well-laid out user interface. Viewpoint UR Engineer from EnerVista also has a drag-and-drop environment that allows for quick debugging of relays and related modules.

Potential buyers who pay attention to installation times will see that GE designed its universal relay family with scalability in mind. The panel of the device can be unfolded (on enhanced and basic models of relays) to allow access to the module bays, and Multilin provides plenty of information and diagrams on proper module wiring in its various product manuals.

UR8FH|A CT/VT module Designed for installation in a general purpose relay series

General Electric Multilin’s UR-8FH is a CT/VT module designed to be installed in the general purpose relay family. It provides the relay with 3-1A/5A phase current transformer, 1A/5A ground current transformer and four voltage transformer terminals. Current transformers and voltage transformers are able to reduce current and voltage to manageable levels for relay monitoring and control, and are necessary to generate important data for relays.

CT/VT modules can use voltage or contact inputs on channels 1 to 4 inclusive or channels 5 to 8 inclusive. The UR manual provides more information on proper relay connections, pointing out important details such as how channels 1 and 5 are connected to phase A, and channels 2 and 6 are connected equally to B. The manual also provides the user with full warnings and notifications, for example, for relay terminals with nominal currents of 1 A or 5 A, connections to the CT must match the secondary rating of the connected CT lest the user wish to cause system damage. In summary, before starting Relay connection, users must read the Universal Relay manual carefully.

Frequently Asked Questions about UR-8FH
Does the UR-8FH protect against ground failure situations when integrated into GE Multilin universal relay systems?
The UR-8FH is described as a CT/VT with standard 4CT/4VT. It has no sensitive grounding function, so it can protect universal relays on ground systems classified as high impedance. The modules with this capability are UR-8G, UR-8J, UR-8M, and UR-8R ordering numbers. These references are newer CT/VT generation. There are also two older CT/VT modules (UR-8B and UR-8D) with sensitive ground fault protection. For example, standard models with 4CT/4VT capabilities do have typical capacities of up to 24 analog current transformers and voltage transformers, as described in all CT/VT modules included in various general-purpose relays. In addition to CT/VT modules, universal relays are equipped with sensor I/O modules. This provides the UR with a DCmA card or RTD to monitor flow, wind speed, temperature, vibration, or pressure. The analog output can also be used to connect the UR to an external PLC or other user interface device. The universal relay also features a digital I/O module containing up to 96 contact inputs and 64 contact outputs.

Frequently Asked Questions about UR-6UH
What does the order code breakdown of the T60 universal relay mean for UR-6UH in the universal Multilin relay?
Let’s take a general purpose relay of the following model: T60-G03-ACH-F8H-H6M-MXX-PXX-UXX-WXX. To understand what each alphanumeric option means and what modules are included in this particular universal relay, you must consider Table 2-4 in the product manual, which breaks down the T60 ordering code for this GE Multilin universal relay. The skeleton order code is T60-***-***-F**-H**-M**-P**-U**-W/X**. Each * represents a variable point in the model number. This allows the end user to select a specific hardware module, such as the CPU, or in this case, a digital I/O module into a generic relay at a specific location. In some cases, * also indicates whether software options are included or not necessarily tangible. If we look at the digital input/output section in the order code detail, we will notice that the underlying digital I/O module can specify a two-digit ordering option in the missing (asterisk) position after the H, M, P, U, or W Spaces. Numeric I/O modules have a two-digit code beginning with a 4 or 6. If we look back at the part number used as an example, we can notice that the H position is followed by a 6M. Therefore, the UR-6M digital I/O module is integrated into this position of the universal T60 relay. Just find XX in the model number, which means there is no module at that location.

UR6CH|Digital I/O module|By providing digital input and output

Ge’s UR-6CH is a digital I/O module that enables UR relays to communicate with auxiliary devices by providing digital inputs and outputs. This particular unit provides eight C-type digital outputs. The Type C digital output is a single-pole double-throw (SPDT) contact, indicating that there is a common point connected to a normally closed contact (NC) and a normally open contact (NO). Form-C can switch between these two outputs, so it is often referred to as a “transition” contact.

The Universal relay family was built with scalability in mind, providing a hinged panel that allows access to the internal module bays for easy installation and upgrades. While the enhanced model and the normal model differ slightly in accessing the module bays, both units provide a relatively simple entry point for hardware modifications.

Potential buyers should ensure that the module they purchase is suitable for their power system needs, as other digital I/O relays in the same family offer different contact forms and functions. The series also offers devices with trip rated A-contacts, solid-state relay contacts or A, C and SSR combinations. Solid state output modules provide fast tripping, high current breaking capability and fast reset time, making them ideal for direct tripping applications.

Frequently Asked questions about UR-6CH
What are the advantages of integrating digital I/O modules into general-purpose relay Multilin GE systems such as UR-6CH?
The digital I/O characteristics allow the universal relay to obtain contact inputs and contact outputs in order to control and monitor auxiliary devices that may be part of the application-specific protection application of the Universal Multiiln relay. Depending on the ordering options for the digital I/O modules included in the universal relay and the number included, the universal relay can have up to 96 contact inputs (rated at 250 volts) and up to 64 contact outputs. There are different types of GE Multilin digital I/O modules, which determine how many inputs and outputs each I/O module has, and which type of input or output a general purpose relay (UR) can use. For example, the UR-6CH has a 6C ordering option. This means that the output provided by this particular digital I/O module is eight Form-C outputs. If multiple such digital I/O modules are found in a particular relay, it increases the number of Form C outputs that a general-purpose relay can use for a particular end application.
