Electrical Wiring
Ordering Information
Note-1 : If input type is selected PTC or NTC (BC = 12, 15, 18, 19 ),
Temperature sensor is given with the device. For this reason,
If input type is selected as PTC, sensor type (V = 0,1 or 2) or
If input type is selected as NTC, sensor type (V = 0,3 or 4) must be
declared in ordering information.
