•In case of TK4N, TK4SP, option output may be limited due to number of terminals.
?“S” represents SSR drive output support models which SSRP function (standard ON/OFF control, cycle control, phase control) are available. “C” represents selectable current and SSR drive output support models.
?Select "R" or "C" type in case of using heating&cooling control and "N" type in case of using standard control.
?CT input of TK4N is available only for the standard model which has alarm output 1.
?Display accuracy:
?At room temperature (23?±5?)
• Thermocouple K, J, T, N, E type, below -100?/Thermocouple L, U, PL? type, RTD Cu50?, DPt50?: (PV ±0.3% or ±2?, select the higher one) ±1-digit
• Thermocouple C, G, R, S type, below 200?: (PV ±0.3% or ±3?, select the higher one) ±1-digit
• Thermocouple B type, below 400?: there is no accuracy standards.
?Out of room temperature range
