Areas of application
The REG216 is used to protect generators and transformers.
The modular hardware and software design allows extremely flexible installation.
The combination of software libraries and hardware allows simple adaptation to the size of the primary system and the required protection scheme.

Modules. As a result, economical solutions can be realized in a wide range of applications.
Economical solution.
The REG216 software system provides a library of protection functions. The following table lists the functions applicable to generator and transformer protection.
Different levels of redundancy can be selected.
The availability and reliability of the protection can be selected according to the application in the following ways
For example, the auxiliary power supply unit for the entire system can be replicated.
Standard interfaces make the REG216 compatible with different process control systems.
Data can be exchanged with higher process control levels, e.g. for one-way reporting of digital status and events, measured values and protection parameters.
The REG216 and REG216 Classic differ in their binary process connection:
– The REG216 uses the E/A module 216GD61a.
– REG216 Classic uses modules 216GE61 / 216GA61 and 216GA62.
Protection functions
All protection functions required for independent protection of generators, power transformers and feeders are available.
All protection functions required for transformers and feeder lines. The system thus replaces multiple relays in conventional protection schemes used for such power system equipment.
Therefore, the system replaces multiple relays in conventional protection schemes used for this type of power system equipment. The table on page 2 describes the most important protection functions.
Simply use your personalcomputer to select the desired protection function from a comprehensive library of protection functions for your specific application.
Use personalcomputer to select the required protection functions from a comprehensive library. No knowledge of computer programming is required.
All setting ranges are very broad, making the protection functions suitable for a wide range of applications. The following main parameters can be set:
– Processing unit assignment
– Input channels
– Pickup setting
– Time delay
– Definition of operating characteristics
– Trip logic
– Control signal logic.
Protection functions can be “connected” to specific input channels by setting the corresponding parameters.
Digital input and output signals can also be logically combined internally:
– The tripping outputs of each protection function can be assigned in a matrix fashion to the channels of the trip auxiliary relay assembly.

– The contact and trip signals can be assigned to the channels of the signaling auxiliary relay assembly.
The channels of the auxiliary relay assembly.
– Each protective function can be blocked by a digital signal (e.g. digital input or trip signal using another protective function).
– External signals applied to the digital inputs can be processed in any desired way.
– The digital signals can be combined to perform logical functions, e.g. an external enable or blocking signal with the output signal of a protective function.
The digital signals can be combined to perform logical functions, such as external enable or blocking signals with the output signals of a protection function or with the output signals of an internal protection function, which can then be used to block one of the other protection functions.
Using the process bus type MVB, the remote input and output unit 500RIO11 can be connected to the REG216 terminals.
By using the RIO580 Remote I/O system, it is possible to expand the number of input and output channels to a larger number.
Mounting the 500RIO11 I/O unit close to the process allows it to be connected to the REG216 terminals via fiber optic connection, which greatly reduces wiring.
