9 With
*1 Although the SD17 is fully universal-input, we have two codes for input specifications as only the current input specification comes with an external
receiving impedance (250Ω). If you do not need an external receiving impedance, select code 8.
*2 Scaling range: -1999–9999 digit; Scaling span: 10–10000 digit
*3 If you select code 08- (24 V AC/DC) for the “power supply,” you cannot select code 8 (sensor power supply) for the “analog output or sensor power supply.”
