Product details

nVent RAYCHEM Elexant 5010i electronic heat tracing control unit. Building on the legacy and proven design of the NGC-20 the Elexant 5010i is suitable for harsher environments, with high accuracy, a faster processor, more memory and is IIoT ready. The Elexant 5010i features all the benefits of local control and the capability for central monitoring for single phase trace heating circuits up to 25 A and is approved for use in hazardous areas. It measures the temperature with up to two RTD(s) connected to the unit. The Safety temperature limiter has a dedicated temperature input. The Elexant 5010i is an advanced field-mountable electronic temperature control system providing local control and central monitoring capabilities, used for single phase circuits up to 25 A and suitable for hazardous areas. 

  1. Elexant 5010i: local control and central monitoring capabilities
  2. Elexant 5010i-LIM: with integrated intelligent safety temperature limiter (SIL 2 device)
