Frequently Asked Questions

Q: What is included in the REX-C100 PID temperature controller kit?

A: The kit includes one REX-C100FK02-V*AN digital PID temperature controller, one 40A solid state relay (SSR 40DA), one K-type thermocouple probe (6mm thread, 1m cable, 0–600°C range), and one aluminium heat sink (60×49×81mm). All components are ready to wire together for a complete temperature control solution.

Q: What voltage does the REX-C100 temperature controller support?

A: The REX-C100 controller accepts an input voltage of 100–240V AC, making it compatible with standard power supplies in North America, Europe, Australia, and most other regions worldwide.

Q: Can I use a different thermocouple or RTD sensor with this controller?

A: Yes. While this kit ships with a K-type thermocouple, the REX-C100 controller supports a wide range of sensor types including K, J, R, S, B, E, N, T, W5Re/W26Re, and PLII thermocouples, as well as Pt100 and JPt100 RTDs. Simply select the correct input type in the controller's settings menu.

Q: What is the maximum load the 40A SSR can handle?

A: The included 40DA solid state relay is rated for loads up to 40 amps, suitable for heating elements up to approximately 4,400W on a 110V supply or up to 8,800W on a 220V supply. Always ensure your load stays within the SSR's rated capacity and use the included heat sink to maintain safe operating temperatures.

Q: How do I install the REX-C100 into a panel?

A: The REX-C100 uses a standard 48×48mm embedded (panel-mount) format with a 45×45mm panel cutout. Slide the unit through the cutout from the front, then secure it with the included mounting clips from behind. Connect your SSR, thermocouple, and power supply according to the wiring diagram.
