Panel flush mount, 8 BI / 8 BO, 110-250 VDC supply
The 7SJ6111-5EB02-1FA0/FF,,F: The 7SJ6111-5EB02-1FA0/FF,F is a Siemens 7SJ61 multifunction protection relay in a 1/3 19-inch housing with 8 binary inputs, 8 binary outputs, and one live status contact. The unit version E specifies panel flush mounting with screw-type terminals accepting direct connection or ring-type cable lugs — a standard fit for retrofit into existing switchgear cutouts where the relay face must sit flush with the panel door. Rated auxiliary voltage spans 110 to 250 V DC and 115 to 230 V AC, with the binary input threshold set at 88 V DC. This means the relay holds the unit on the grid across the common station battery voltages (110/125/220 VDC) without an external converter, provided the DC supply stays above the 88 V threshold for reliable input sensing. Measuring inputs are configured for Iph = 1 A, Ie = 1 A with a minimum detectable current of 0.05 A — sized for direct connection to CT secondaries in medium-voltage feeder protection schemes where 1 A CTs are standard.
Service interface and regional defaults
The service interface (Port C) is an electrical RS485 port running DIGSI 4 protocol, with modem and RTD-box support. This is the commissioning engineer's download port — the RS485 physical layer matches the legacy DIGSI 4 cable, so no USB converter is needed for initial parameterisation on site. The default language is English (GB), with other languages selectable via DIGSI. This covers the common frequency and protection-curve requirements for export panels or multi-standard installations. Fault recording is included as standard (position 15), meaning the relay captures oscillographic event data for post-fault analysis — essential for coordinating protection operations and verifying that the trip sequence held the unit on the grid as intended.
