This auxiliary contact from Siemens' SENTRON range accurately signals switching or malfunction states. Use it in conjunction with your main contacts, such as circuit breakers, relays and contactors. It changes states along with these switches to pass data from a circuit to a logical controller, which then either turns a linked device on or off. The unit ensures reliable and efficient power distribution to applications by preventing oversupply or undersupply in interlocking circuits or logic and sequence controls with low to high loads. You can use this versatile device with a wide variety of components such as pushbutton controllers, motor control schemes and industrial control applications.

• Screw terminals secure connections physically and electrically to ensure reliable conductivity and power transmissions
• Operating temperature range of -5°C to +40°C for use in demanding settings
• DIN rail mounting allows for quick and easy installation

An auxiliary circuit transmits signals to detect, supervise or control the functional status of the main circuit. This high-performing Siemens auxiliary contact effectively controls your auxiliary circuits and establishes the proper functioning of devices.
