Applications / Use Case

The Allen Bradley 100-SA20 auxiliary contact block serves critical functions in motor control and automation systems where additional control contacts are required beyond the base contactor configuration. It is commonly deployed in applications requiring remote indication of contactor status, interlocking sequences between multiple contactors, or feedback signals to programmable logic controllers. Manufacturing facilities utilize this contact block to provide status monitoring for conveyor systems, pump controls, and machine tool operations. The normally open contact configuration makes it particularly suitable for alarm circuits, pilot light indication, and control relay triggering. Process industries leverage the 100-SA20 for coordinating multiple motor starters in sequential operations, ensuring proper startup sequences for equipment like fans, blowers, and compressors. Its side-mounting capability allows engineers to add control functionality without redesigning panel layouts or requiring additional DIN rail space. The screw terminal design accommodates a wide range of wire gauges, making it adaptable to both new installations and retrofit projects where existing wiring infrastructure must be maintained.
