Note.
Using internal transmitter power supply.
Fit the CJ sensor supplied if Analog Input 1 or 2 are THC inputs.
(Alternatively, it is possible to use an external fixed cold [reference] junction, if the controller is
programmed for use with millivolt inputs and the appropriate thermocouple linearizer is selected.)
Analog Input 2 can be used only with THC inputs if Analog Input 1 is also used as a THC input.
For mA input types, to ensure loop continuity when the indicator is switched off, fit a 2V7 Zener diode
as shown.
3-lead RTD: 3 leads must have equal resistance, not exceeding 20  each.
