Siemens 3TX7112-1LF13 DPDT Relay 8-Pin Octal 120VAC

Siemens SIRIUS 3TX7112-1LF13 Premium socket relay is a DPDT (2 Form C) plug‑in device that switches two independent circuits from a 120 VAC control coil, all housed in an 8‑pin octal base for easy panel mounting. It operates on 120 VAC with a 50/60 Hz input and is rated for up to 10 A at 120 VAC, making it suitable for common control loads in industrial environments. The LF13 variant includes Premium LED status indication and a mechanical flag to confirm operation at a glance, enhancing diagnostics in enclosures. This relay uses Siemens socket options such as 3TX7144-1E2 or 3TX7144-4E2, aligning with standard plug‑in footprints for quick installation and replacement within the SIRIUS premium lineup. Applications include HVAC and building automation, machinery control, and any control panel where two Form C contacts must switch separate AC circuits from a single relay coil. Its compact octal base and plug‑in design simplify wiring and maintenance while delivering reliable dual‑circuit switching in a single plug‑in unit.
