4.6.6 Analog Inputs – CMF310 Controllers
* Using internal power supply
** Analog Input 2 can be used only with THC inputs if Analog Input 1 is also used as a THC input.
*** To connect the CJ, put LK3 into position B. To disconnect the CJ put LK3 into position A.
**** For mA input types, to ensure loop continuity when the CMF310 controller (or CMF160 indicator) is switched off, fit
a 2V7 Zener diode
Note
. 3-lead RTD: 3 leads must have equal resistance, not exceeding 20
each.
