• 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)
• Residual voltage: 1.5 V max.
• (GT2-71MCN/71MCP only) Surrounding air temperature: -10 to +45°C
*3 HH and LL are not available for GT2-71MCN/71MCP.
