Maintain high levels of reliability in industrial process-control applications with this Allen Bradley auxiliary contact from Rockwell Automation. It can be fitted to protection and control devices such as relays and circuit breakers to signal switching or malfunction states. The compact unit is fixed directly into a main contact, so it doesn't take up much space. Dual numbering on both sides of the device gives you a choice of mounting on the left or right side of a contactor for enhanced versatility.

• Screw terminals for simple installation and a reliable join
• Recyclable at end of life for a reduced carbon footprint
• Electronically compatible contacts to reduce the risk of machine downtime
• Safe positive guidance to prevent all poles from being closed at the same time

• IEC 947-5-1 (International Electrotechnical Commission)
• DIN 19240 (Deutsches Institut für Normung)

An auxiliary contact changes state when the main contact does. It transfers data from an electrical circuit to a logic controller, which in turn gives instructions to the linked devices about whether to turn on or off. You can also use it as a stand-alone hardware control unit.
