The standard battery is a 3.0V DC lithium battery with a lifetime of 12 years. It can be also applied with a 3.6V DC lithium battery with regulator for a lifetime of 16 years, or with a main supply of 24V AC or 230V AC. These power supply can also be retrofitted in the field.Characteristics for main supply :230V AC or 24V AC main supply module The pulse output for the model 474 is realised with a stand-ard mounted module. The module has a galvanic isolation. (Fig. 1)There could be connected a pulse cable to the terminal onthese module, with a maximumcable leugth of 10m.The technical information...
