FAQs
Q1. Does TC544C support both thermocouples and RTD sensors?
Yes—supports J, K, T, R, S TC, and PT100 RTD.
Q2. Are the outputs user-selectable?
Yes—Output 1 can be Relay or SSR.
Q3. Does the controller support heat-cool operation?
Yes—full heat-cool PID with separate P-cool and cycle time.
Q4. What is the display advantage?
Dual display allows PV (Process Value) and SV (Set Value) to be shown simultaneously.
Q5. Is EMC compliance provided?
Yes—tested against IEC 61326-1, CISPR-11, and IEC 61000-4-2/3/4/5/6/11.
