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 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.
