2-4 Appendix

12-3.  Sensor wiring

Refer to figure 12-1, which includes drawings that outline sensor wiring. The EXA SC202 can be used 

with a wide range of commercially available sensor types if provided with shielded cables, both from 

Yokogawa and other manufacturers. The sensor systems from Yokogawa fall into two categories, the 

ones that use fixed cables and the ones with separate cables.

To connect sensors with fixed cables, simply match the terminal numbers in the instrument with the iden-

tification numbers on the cable ends. For details, refer to corresponding IMs.
