| Type EA11 Application Digital, electronic display instrument without power supply to indicate analogue current signals. Suited for the mounting in cases, service cabinets and measuring stations. An essential advantage by using this instrument is the previous reduction of costs by partial saving of the neccess-ary cabling as well as the power supply. The operating safety of installations is considerably increased because the function of instrument is not affected by power failure etc. The coupling between the measuring circuit and the power supply of convential electronic displays does not exist in this case. | |||||||
