Binary Input BI 2 (X5)

The relatively slow but interference-free binary input BI 2 with a wide input voltage range is used, for example,
to detect the minute pulse for synchronizing the SIPROTEC 3 devices.
This input operates in parallel with the optical input R2. However, a signal must not be present simultaneously
at R2 and BI 2.
The binary input BI 2 is not suitable for fast operations. To allow for processing, the pulse must be present for
more than 5 ms. The pickup voltage can be increased to about 75 V using a jumper.
2.2.2.5

Electronic Relay Output K2 (on X6)

The electronic relay output K2 is a fast, electronic load disconnecting relay for triggering the binary inputs of
SIPROTEC 3 devices using the voltage from the station battery.
