1. Specifications
(1). Device Specifications
*1: Supply electric power from a power supply unit for the transmission line or an outdoor unit. Furthermore, the power consumption
factor of the M-NET circuitry of this unit is "1/4".
*2: Configure the dip switch settings for the analog input method to use.
*3: The measurement error for the system includes the measurement error for this unit, sensor, and wiring.
a%FS (full scale) = a% × ([measurement range's upper limit value] - [lower limit value])
*4: Settings for the interlock function are performed from the Maintenance Tool. For details, refer to the operation manual for the
Maintenance Tool.
*5: M3 and M3.5 are sizes of the screw on the terminal block (ISO metric screw thread). The number indicates the screw diameter
(mm).
