          *1 When using the DIN-rail mount type, always mount it to a DIN-rail (mounted to a metal plate), and when adding expansion units, always use the end unit (OP-26751).
          *2 When adding expansion units, there are the following restrictions according to the number of connected units.
          [When 2 to 8 units are connected including the main unit]
          Power supply voltage: 20 to 30 VDC, Control output current: 20 mA or less, (GT2-71MCN(P) only) Ambient temperature: -10 to 45 °C
          [When 9 to 15 units are connected including the main unit]
          Power supply voltage: 20 to 30 VDC, Control output current: 10 mA or less (including the DL-RB1A output current), Residual voltage: 1.5 V or lower, (GT2-71MCN(P) only) Ambient temperature: -10 to 45 °C
          *3 The GT2-71MCN(P) does not have HH/LL.
