It snaps onto a DIN rail (22.5 mm wide, 100 mm tall, 124.5 mm deep) and runs on 24 V DC, drawing 1 W operating power with a 4 A inrush peak at 24 V. ## PROFINET IO connectivity This module speaks PROFINET IO (conformity class B) and supports LLDP and SNMP for network management. It does not carry IRT, MRP, NTP, TCP/IP, HTTPS, PROFIsafe, or PROFIBUS DP — so it is a straightforward IO device for standard cyclic data exchange, not a safety-over-EtherCAT or time-synchronized motion node. The PROFINET interface handles 64-bit input and 64-bit output data. Snap it onto a DIN rail or screw-mount with the optional push-in lug. Mounting position is any orientation. The spring-cage terminals accept 1x or 2x solid conductors 0.5–1.5 mm² (AWG 20–16 solid or stranded). Shock-rated to 15 g / 11 ms; vibration tested per IEC 60068-2-6 at 0.75 mm displacement over 5–500 Hz.","metaTitle":"Siemens 3SK2511-2FA10 SIRIUS PN Interface Module, PROFINET I","metaDescription":"Siemens 3SK2511-2FA10 SIRIUS interface module with PROFINET IO protocol, 1 W operating power, IP20, snap-on DIN rail mount.
