IOA RPSS-I-I/HART/EX - Power/input isolating amplifier

Ex ic repeater power supply and input signal conditioner, HART for VIP I/O-Marshalling base elements: Transmits 0/4 ... 20 mA signals from the potentially explosive area (zone 2, CID2) to a load (active or passive) in the safe area. 3-way electrical isolation

  • Two-stage progressive release allowing for voltage checks with field-powered devices
  • Channel for marking accessories
  • Integrated keying reduces possible user error during replacement
  • Signal disconnect with test points
  • Bidirectional HART signal transmission
  • 3-way electrical isolation
