Siemens Industrial Controls 3TX7110-5BC03C SPDT Relay 15 Amp 24 VDC

The Siemens Industrial Controls 3TX7110-5BC03C SPDT Relay is an electromechanical switching component used in control panels to manage low-voltage control signals for higher-load equipment. It operates with a 24 VDC coil and a contact configuration rated up to 15 amps, enabling it to switch electrical circuits accurate within air handling units, chillers and furnace control assemblies in HVAC systems applications. It is installed inside control panels where it operates as an interface between thermostats, or building automation controllers and components such as compressors blower motors, and solenoid valve. Its role is to ensure controlled switching and signal isolation within systems maintaining operational coordination and system protection in automated heating and cooling conditions.
