The 2093-PRS4 Kinetix 2000 4-Axis Power Rail by Allen-Bradley is an electrical device designed with a circuit board and copper bus bars and connectors for modules installation. It provides power and control signals from the IAM converter installed on the leftmost part of the Kinetix 2000 Axis Modules (AM) which powers and controls servo motors or other devices that produce motion. It provides a common mounting mechanism for a single IAM and 3 AM modules, a shunt module, or a slot filler (PRF). The 2093-PRS4 power rail has 4 available inverter slots and is used in a 4-slot inverter system. The 2093-PRS4 has a 0-50 °C (32-122 °F) functional temperature range at a relative humidity range of 5-95% without condensation and it is stored at a non-operating temperature range of -40-85 °C (-40-185 °F). 

The connector pins of the 2093-PRS4 are conformally-coated to prevent long-term damages and it is rated as an IP2X Open-Device for use in a Pollution Degree 2 Environment. It is designed for mounting even at an altitude of 1000m (3281ft) without de-rating but it will slowly de-rate at 15% for every additional 1000m and it is built to withstand a 2G operational vibration at 55-500Hz and an operational shock of 15G. It is cUL-us, CE, and IEC-certified and it weighs 0.64Kg (1.4lb) and measures 210mm x 167.5mm x 32.66mm (8.26inin x 6.59in x 1.29in).
