iZAZ100

is a series of single function, communication-less digital protection relays with up to three measurement inputs. It includes voltage, current, earth-fault, frequency, and special relays. It is characterised by accuracy and reliable operation, a broad range of start-up value settings and easy control via an LCD display and a functional menu layout. They can be used in any environment not requiring a large number of inputs/outputs and extensive protection functions, where small enclosure sizes, low energy consumption and cost reduction are important. Apart from the protective functions, these devices are also equipped with measuring and signalling functions. Structural elements of the devices are mounted in a non-flammable fuse type enclosure equipped with screw terminals and suitable for mounting on a TS 35 rail. These devices are an interesting alternative in simple protective and industrial electrical power automatic control systems.

iZAZ200

is a series of powerful, communication-enabled digital multifunctional relays with up to four measurement inputs. These devices are characterised by high accuracy and reliable operation. They can be used in automatic control systems as advanced and functional power, voltage, current, frequency and earth-fault protection devices. After a proper hardware and software configuration, these devices support automatic controls for automatic frequency load shedding, automatic reclosing and automatic voltage load shedding. Apart from the protective functions and automatic controls, the devices offer functions for measuring, recording, control, and communication via a RS-485 serial port and a USB port. Structural elements of these devices are mounted in an aluminium enclosure suitable for flush-mounting.

iZAZ300

is a series of digital, multi function protective relays with up to eight configurable measurement inputs. These devices enable execution of complex protective algorithms and customisation of the number of inputs/outputs depending on the requirements of the protected facility. These devices are characterized by high accuracy and reliable operation. They can be used in lean automatic protection systems for engines, transformers and MV lines, as well as small generators. These devices support automatic controls for automatic frequency load shedding, automatic reclosing, automatic transfer switch and automatic voltage load shedding in applicable hardware and software configurations. Apart from the protective functions and automatic controls, the devices offer functions for measuring, recording, control, and communication via a RS-485 serial port and a USB port. Structural elements of these devices are mounted in an aluminium enclosure suitable for flush-mounting. Easily programmable functional structure ensures high flexibility in adapting these devices to the requirements of the protected facility during the manufacturing and commissioning phases.

iZAZ400

is a versatile multifunctional relay with a bay controller enabling comprehensive protection of medium voltage bays (incoming, bus coupler, outgoing, transformer, engine, measurement, etc.), high voltage bays and small generators, and generator-transformer blocks. Thanks to the modular design, the hardware configuration can be optimally customised to the requirements of the protected facility. A 7-inch colour display ensures legible presentation of the bay synoptic system with essential measurements and additional information. The operation logic is easily programmable via a graphic editor, which enables legible and transparent implementation of various applications, both typical and dedicated, including specific requirements for a given facility. Bay controller enables the control of circuit-breaker and switching devices, while maintaining the required functional interlocks.

iZAZ600

is a device designed for generators and generator-transformer blocks with a requirement to process a greater number of binary inputs/outputs and analogue tracks. The user can choose from up to 48 analogue channels, 128 binary inputs and 233 relay outputs, including high-power reed relay outputs. The higher number of processed measurement signals allows for comprehensive protection of generator-transformer blocks, HV transformers or generators operating directly on busbars. The control panel with a 7-inch colour touch display enables legible presentation of the bay layout with essential statuses and measurements. iZAZ600 is offered as a standalone device to be used in protection cabinets or as a ready-made protection cabinet. In typical solutions, two cabinets are used as system A and B, or one cabinet with two embedded iZAZ600 relays

iZAZ Tools

is a utility software for controlling the whole family of iZAZ devices via a PC with Microsoft Windows operating system. iZAZ Tools software enables comprehensive control of the device in terms of configuration and settings (with configuration editing in graphical mode), status check and control of the device and protected facility, as well as interpretation and analysis of the event and interference records (using the iREC software included in the bundle). The communication with iZAZ is executed via the MODBUS protocol using one of three interfaces: USB, RS-485, TCP/IP.
