Features
E-1071-073
The E-T-A Remote Power Controller E-1071-073 is an electronic ON/
OFF control module with protective functions and is suitable for resistive
and inductive loads such as solenoids in rolling mills and other large
plant applications. It is specifically used in plant modernization where
the load circuit supply should be maintained at DC 24 V.
