At-A-Glance Executive Brief
- Model: 6GK5116-0BA00-2AA3, SCALANCE X116
- Brand: Siemens
- Part Type: Unmanaged industrial Ethernet switch
- Lifecycle status: OEM obsolescent, stocked for factory brownfield network retrofits
- System compatibility: Profinet Class A, SIMATIC PLC and DCS control networks
- Weight: 0.375 kg
Technical Introduction
Plant Ethernet communication drops stop PLC to field device data exchange when this switch fails. This DIN rail mounted unmanaged unit delivers plug-and-play 10/100Mbps Ethernet switching for factory control cabinets. It includes sixteen RJ45 copper ports, redundant 24V AC/DC power inputs and a fault relay contact for remote alarm signaling. Individual port LEDs show link and activity status to speed troubleshooting. No IP configuration is required, so technicians swap hardware without modifying existing network logic. Facilities hold spare units to limit downtime while planning legacy network migration.
- Best Suited For
- Profinet star topology control networks
- DCS and PLC rack cabinet network expansion
- Direct drop-in replacement for existing SCALANCE X116 hardware

Field Engineer’s Tech Notes
- The fault relay contact is passive and requires external supply to trigger SCADA alarms. Do not assume the relay will send alerts without proper auxiliary wiring.
- Avoid mixing Cat5e and older Cat3 cabling on the same switch. Mismatched cable grades create intermittent link flapping that mimics PLC I/O mapping faults.
Adaptive QA & Testing Protocol
Each switch is bench tested on a Profinet test network. We verify all sixteen RJ45 ports for link negotiation at both 10Mbps and 100Mbps speeds. Redundant power inputs are tested by cycling each supply path independently to confirm seamless power transfer. Fault relay contact operation is validated by triggering loss of power. Full test reports or bench test video clips are available upon request.
Buyer’s FAQ
Q: Is 6GK5116-0BA00-2AA3 the same as the newer 6GK5116-0BA00-2AC2? A: They share the same port layout, but hardware revisions differ. 6GK5116-0BA00-2AA3 is the original discontinued SCALANCE X116. Verify network topology before substituting the newer variant.
Q: What warranty covers refurbished and NSFP 6GK5116-0BA00-2AA3? A: Refurbished and NSFP units carry a 12-month hardware warranty. Coverage excludes damage from overvoltage, miswiring or surge events on the Ethernet lines.
Q: What lead time should I expect? A: Stocked units ship 3–7 business days. If inventory is depleted, lead time increases while we source available surplus units.
Q: Does this switch require programming before installation? A: It is unmanaged, no configuration needed. Plug in Ethernet and power cables and the unit begins forwarding traffic immediately.
