The Power Rail is a simple plastic insert for the DIN mounting rail according to EN 60715. It solves all of the power supply wiring problems involved when mounting terminal blocks. A wide range of isolators is available. These are supplied with auxiliary power by simply snapping them onto the Power Rail. The power supply to the 2 Power Rail leads is achieved either by means of a power supply module, or via the terminal blocks of a termination board. By comparison, the isolator power supply connections are only suitable for the supply of the individual modules. They are not suitable for the supply of the Power Rail or to further conduct the Power Rail voltage. On the PR-05 Power Rail, 2 additional poles are available for the bus connection of the isolators. The Power Rail is supplied in 50 cm sections. It can be cut every 4 cm along its length, at the positions indicated, to suit individual requirements. Gold plated contacts are provided to ensure secure electrical contact. Please use the standard type UPR-05 for new systems.
