*1 Restrictions when S-HSPD is selected
Area detection, Area % Mode, DATUM, Rising edge, and Falling edge cannot be selected for Detection Mode.
Output timer, Limit Detection, and Display Gain cannot be used.
FULL cannot be selected for the ECO function.
*2 Restrictions when HSPD is selected
Display Gain cannot be used.
*3 The input time becomes 25 ms (ON)/25 ms (OFF) when external calibration input is selected.
*4 When expanding the system to 9 or more units, use a power supply voltage of 12 V or higher.
*5 The load current is excluded. The power consumption including the load when the maximum number of units are connected is 38 W max.
*6 When expanded by 1 to 2 units: -20°C -4°F to +55°C +131°F. When expanded by 3 to 10 units: -20°C -4°F to +50°C +122°F.
When expanded by 11 to 16 units: -20°C -4°F to +45°C +113°F. When using 2 outputs, 1 unit is counted as 2 units.
The prescribed values for the ambient temperature assume that the sensor amplifi er has been mounted on a DIN rail installed on a metal surface.
Exercise special care when installing the product in an airtight space.
