Siemens Industrial Controls 3TX7112-1DF13C Relay
The Siemens 3TX7112-1DF13C is a performance-grade DPDT octal relay designed for reliable switching in demanding HVACR control circuits and industrial automation panels. This 8-pin plug-in relay features a 120V AC coil and is rated for 16A resistive loads, making it a rugged alternative to standard general-purpose relays. Engineered for heavy-duty cycling, the Siemens 3TX7 series utilizes silver alloy contacts to minimize arcing and ensure long-term electrical conductivity under varied thermal conditions. The octal base configuration allows for rapid integration into existing DIN rail mount sockets, reducing downtime during field replacements. Technicians typically deploy this 120V relay for interlocking circuits, motor starting assistance, and pilot duty applications where high inrush currents are common. Its compact footprint does not compromise its switching capacity, providing a stable interface between low-power control signals and high-amperage equipment loads.
Key Benefits:
- High Amperage Rating: The 16A DPDT contacts allow for simultaneous control of two independent circuits, handling higher loads than standard 10A variants.
- Standardized Octal Design: Fits universally into 8-pin relay sockets, simplifying inventory and field service for legacy and modern panels.
- Mechanical Reliability: Built by Siemens for industrial-grade switching, ensuring consistent contact pressure and vibration resistance in mechanical rooms.
- 120VAC Control: Optimized for standard American line voltage control systems, eliminating the need for step-down transformers in many relay logic applications.
Common Questions:
Can this relay be used with DC voltages on the coil?
No, the 3TX7112-1DF13C is specifically designed for a 120V AC control signal. Applying DC voltage to the coil will result in failure or improper seating of the contacts.
What is the difference between this and a standard 8-pin relay?
While the pinout is standard, this model features 16A heavy-duty contacts, whereas many standard octal relays are limited to 10A or 12A. Always verify the amperage requirements of your inductive load.
Is a socket included with this part?
This is the plug-in relay component only. It must be paired with a compatible 8-pin octal base for DIN rail or surface mounting.
