When connecting 2 to 8 units including the main unit

• Supply voltage: 20 to 30 VDC

• Control output current: 20 mA max.

• (GT2-71MCN/71MCP only) Surrounding air temperature: -10 to +45°C

◆

When connecting 9 to 15 units including the main unit

• Supply voltage: 20 to 30 VDC

• Control output current: 10 mA max. (including the output current of the DL-RB1A)
