* 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 with THC inputs only if analog input 1 is also used as a THC input.
**** For mA input types, to ensure loop continuity when the controller is switched off, fit a 2V7
Zener diode as shown.
