The 2094-PR4 Kinetix 6000 Power Rail is a 4-axis power rail and an integral part of the Kinetix 6000 drive system. It transmits power and signals to all other Kinetix 6000 accessories attached to it via the IAM attached on the left rear of the rail. The 2094-PR4 can support a single IAM module and 3 additional modules. It can also work with the 230V and 480V class modules. The 2094-PR4 Kinetix 6000 Power Rail is only limited to a 4-inverter slot system, and when the 2094-PR4 inverter slot exceeds the minimum required number of inverter slots in the system, the unused inverter slot must be filled by a slot filler module. Additionally, the inverter slot pins of the 2094-PR4 are covered with a protective covering which guards against foreign objects that may lodge inside the slot and damage it.

The 2094-PR4 Kinetix 6000 Power Rail is c-UL-us, CE, and Functional Safety-certified for use in various regions. It also has similar environmental specifications to all other Kinetix 6000 components. It has a functional temperature range of 32-122 °F at 5-95% non-condensing relative humidity both when operating and at rest. It can function without de-rating even at an altitude of 1000m (3281 ft). The 2094-PR4 has a 3-perpendicular directional 15G shock pulse and a 5-55Hz 2G maximum operational vibration. The device weighs approximately 2.18Kg (4.8lb) and has rail dimensions of 398.78mm (15.7in) x 373.38mm (14.7in).
