The fuse-protected power feed module can supply up to 150 individual devices depending on the power consumption of the devices. Collective error messages received from the Power Rail activate a galvanically-isolated mechanical contact. Power Rail UPR-03 The Power Rail UPR-03 is a complete unit consisting of the electrical insert and an aluminium profile rail 35 mm x 15 mm. To make electrical contact, the devices are simply engaged. Profile Rail K-DUCT with Power Rail The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables. Due to this assembly no additional cable guides are necessary. Release date 2012-07-31 16:00 Date of issue 2015-02-16 236982_eng.xml Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
