Allen Bradley Auxiliary Contact Block, 2NO/2NC, 4PST - 100-KFA22Z
This Allen Bradley contact block from Rockwell Automation is used in relay logic circuits for simple signal switching. It's a 4-pole device that can control as many as four circuits, reducing the amount of wiring needed in your circuitry. It has two normally open and two normally closed contacts that function alongside the relay or contactor it's connected to. Use the unit's screw terminals to make easy connections to external devices without the need for any special tools. You'll find contact blocks like this one commonly used to control external motor functions, such as light-emitting diode (LED) indicators.
• Wide operating temperature range of -25°C to +60°C for use in harsh environments• Can be daisy-chained with other auxiliary contact blocks for increased productivity• Supplied with an on/off toggle switch for extra control and safety
