Current relays


 

DOLD current control modules, available from ELTRON, provide reliable monitoring of current values in single-phase and three-phase installations. They protect devices against overload, insufficient current consumption or no load, which is crucial for the safety of machines, motors and automation systems.

DOLD products can be precisely adapted to different measuring ranges – from 5 A to 100 A – with relay outputs 1 C/O, 2 C/O or in an INV/NO configuration. They are the ideal solution for industrial applications, HVAC, pump systems, compressors and electric drives.

The ELTRON range includes, among others:

  • Compact modules for single-phase systems – such as MK 9053N, IK 9270 and IL 5201/20007, with widths starting from 17.5 mm,
  • 3-phase solutions – e.g. IP 9277, SP 9270CT, IL 9271, offering multi-channel monitoring and dual relay outputs,
  • Modules with integrated current transformers – such as SP 9278CT, facilitating installation in confined spaces,
  • Expandable solutions – e.g. IP 9278, enabling integration with larger monitoring and control systems,
  • Specialised versions with high current range (e.g. SL 9271CT – up to 100 A) and versions with different operating logic and response delay.

All DOLD current control modules available from ELTRON comply with industrial requirements, offer fast response times and high reliability in long-term operation.
