External connection
Dedicated signal cable (AKB611)
*1: Include the tolerance which is caused by dedicated signal cable AKB611(up to 5 m).
In case of the cable length of AKB611 is more than 5 m, 15 mΩ shall be added to the accuracy per each 5 m.
*2: These values apply for the case when the resistance of field wiring line A and line B are the same value.
If the difference of resistance between line A and line B happens, the different value among them needs to be added.
*3: SAR145 also supports JIS C 1604-1989 JPt100.
*4: Wiring resistance for signal cable of INnA, INnB and INnC must be identical.
*5: When connecting the RTD modules, use the resisters composed of the passive parts. If an instrument that simulates resistance electronically is connected, it may cause error between reading and actual values. Do not connect voltage signal to the modules.
