FAQ
Q1. What sensors are supported?
J-type or K-type thermocouples and PT-100 RTD (factory configured).
Q2. What control modes are available?
ON-OFF and Time Proportional (TP), depending on the factory setting.
Q3. How many outputs does the controller have?
It includes 1 relay output for basic heating or cooling control.
Q4. What is the difference between MDC-1901 and MDC-2901?
Only the panel size and depth differ—functionality is identical.
Q5. Is this suitable for heating and cooling?
Yes. The relay can be configured for either heating or cooling actions.
Q6. Does it support PID?
No. The MDC Series supports ON-OFF and TP modes only.
