The ABB AF400‑30‑11 is a heavy‑duty three‑phase power contactor from ABB’s AF series — designed for motor starters, industrial load switching, and distribution applications. It provides three main normally‑open contacts for controlling 3‑phase power circuits, plus built‑in auxiliary contacts for control or signalling. The contactor supports a wide range of coil/control voltages (AC or DC depending on version) and is suitable for high-current, high-power applications (motors, large loads, industrial equipment). Its robust construction, high breaking and making capacity, and IEC/UL compliance make it a versatile choice for demanding power control and motor‑control applications.

The Honeywell 51454472-175 8C-PDODA1 Digital Output Module delivers precise digital control, offering seamless integration into industrial automation systems with its 24V output capability.

The Emerson C200-04400170A is a Bettis C-Series pneumatic scotch yoke actuator. Designed for reliable quarter-turn valve automation, it converts pneumatic pressure into rotary motion to operate ball valves, butterfly valves, and plug valves in industrial applications. The "044" torque code indicates approximately 4,400 in-lb output torque, while "0170A" specifies a particular spring configuration or option set for specific application requirements such as different fail-safe position or spring torque characteristics.
