DIN rail (Power Rail)

The Power Rail consists of a 35 mm DIN rail with gold-plated inlays. Gold-plated connectors on the bottom of the modules simply snap onto the Power Rail. This eliminates point-to-point connections and provides a path for the collective error message from individual isolators. Power Rails are available in two versions:

  • 3 rails (UPR-03) that supply power and error signals
  • 5-rail version (UPR-05) with 2 rails for power and three rails for serial data exchange

Power feed modules

Power feed modules provide the link between the power rail and the external 24 V source. A redundant power supply with two power feed modules offers a high degree of safety. If a fuse opens in one module, the second module continues to energize the Power Rail. An alarm contact within the unit indicates a power loss or the collective error message from the individual I/O modules.
