216GD61a

This assembly is used in the version of

REG216. It provides eight tripping relays,

each with powerful, potential-free tripping

contacts (with surge circuits), 16 auxiliary

relays and 16 optocoupler input circuits. Max.

four assemblies can be provided.

Input auxiliary relay assembly 216GE61

Up to 16 auxiliary relays can be accommodated, providing complete potential separation of digital input signals.

Output auxiliary relay assembly 216GA61

Up to 16 auxiliary relays can be accommodated providing complete potential separation

of digital output signals (two contacts per signal).

Tripping auxiliary relay assembly 216GA62

Up to eight powerful, potential-free tripping

contacts and circuits, which provide highspeed operation (surge circuit) with reduced

consumption after operation (economy circuit) are provided.

The tripping auxiliary relay assembly can be

optionally fitted with a tripping logic diode

matrix to enable direct coupling of external

signals. REG216 can also read and process

external signals via digital inputs.

The REG216 is intended for the protection of

generators and block transformers.

The modular hardware and software design

allows an extremely flexible installation.

Simplicity of adaption to the size of the primary system and the desired protection

schemes are achieved through the combination of a software library and hardware

modules. Economic solutions can thus be

achieved in the full range of applications for

which it is intended.

The REG216 software system offers a library

of protective functions. Functions suitable for

generator and transformer protection are listed in the table below.

Different degrees of redundancy can be selected. Availability and reliability of the protection can be chosen to suit the application by

duplicating e.g. auxiliary supply units of the

whole system.

Standard interfaces make REG216 compatible with different process control systems.

Data exchange with higher process control

levels are possible, e.g. one-way reporting of

digital states and events, measured values and

protection parameters.

REG216 and REG216 Classic differ with

regard to the binary process connection:

- REG216 uses the E/A-module 216GD61a.

- The REG216 Classic uses the modules

216GE61 / 216GA61 and 216GA62.
