The 860R-600, 860R-2000, & 860R-5000 are no longer in production see Discontinued Products.
The recommended replacement is Danisense DS Series High Precision Current Transducers.
For the 860R-600 and the 860R-2000 the control is a common
unit and either 600A or 2000A Heads may be connected. The Ultrastab 860R Transducer System is similar to the LEM Danfysik Saturn but only offers voltage output, see LEM Danfysik Saturn for current output models.
With either of these heads the full scale current range
may be set by range Programming Plugs in 40A or 125A steps
respectively. The 860R-5000 uses a modified control and
range programming is not available.
