*1 Counted as one output when added to a NU Series communication unit.
*2 Input time is 25 ms (ON)/25 ms (OFF) when the external calibration time is selected.
*3 If more than one unit is used together, the ambient temperature varies with the conditions below. Mount the units on the DIN rail with mounting brackets and check that the output
current is 20 mA or less for a uni t .
One or two more units connected: -20°C to +55°C ; 3 to 10 more units connected: -20°C to +50°C; 11 to 16 more units connected: -20°C to +45°C .
