Without the battery module, user data (such as memory bit statuses, data blocks, timers, counters) are saved by an internal high-power capacitor for around 5 days. The program is always stored in non-volatile memory (maintenance-free). The battery module is inserted into the memory module slot.\par\trowd\trgaph70\trleft0\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx10165\pard\widctlpar\intbl\pard\intbl\sb60\sa60\plain\f0\fs14\b\cf3 Device versions\cell\intbl\row\pard\trowd\trgaph70\trleft0\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx2245\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx4225\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx6205\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx8185\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx10165\pard\widctlpar\intbl\pard\intbl\sb60\sa60\plain\f0\fs14 Version\cell Supply voltage\cell Input voltage\cell Output voltage\cell Output current\cell\intbl\row\pard\trowd\trgaph70\trleft0\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx2245\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx4225\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx6205\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx8185\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx10165\pard\widctlpar\intbl\pard\intbl\fi-170\li227\sb60\sa60\tx113\tx227\plain\f1\fs14 \'b7\plain\f0\fs14\tab DC outputs\cell \pard\intbl\sb60\sa60 24 V DC\cell 24 V DC\cell 24 V DC\cell 0.75 A, transistor\cell\intbl\row\pard\trowd\trgaph70\trleft0\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx2245\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx4225\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx6205\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx8185\clbrdrl\brdrs\brdrw5\clbrdrt\brdrs\brdrw5\clbrdrr\brdrs\brdrw5\clbrdrb\brdrs\brdrw5\cellx10165\pard\widctlpar\intbl\pard\intbl\fi-170\li227\sb60\sa60\tx113\tx227\plain\f1\fs14 \'b7\plain\f0\fs14\tab Relay outputs\cell \pard\intbl\sb60\sa60 85 to 264 V AC\cell 24 V DC\cell 24 V DC, 24 to 230 V AC\cell 2 A, relay\cell\intbl\row\pard\pard\sb100\par }
