Miniature DC Temperature / Process Controller

The CT325 Miniature DC Temperature Controller is designed for use with Minco Thermofoil™ heaters and RTD or thermistor sensors. It offers inexpensive on/off temperature control of your process or equipment with accuracy many times better than bimetal thermostats. You can control temperatures up to 200°C (RTD sensor) or 75°C (thermistor). Easily read and adjust the set point temperature using your voltmeter, then monitor the actual signal temperature at the other end. Operating from your 4.75 to 60 volt DC power supply, the controller can switch up to 4 amps power to the heater. A bright LED indicates when power is applied to the heater. The entire unit is epoxy filled for moisture resistance, with a through-hole for a mounting bolt. A terminal block provides the power input, sensor input and heater output connections.

• Miniature package: 1" × 1" × 1.5"

• Solid state on/off control with adjustable setpoint

• Uses standard 100 Ω or 1000 Ω platinum RTD or 50 kΩ thermistor sensor input

• Single DC power source provides power to the controller and heater up to 240 watts

• Simple setup with voltage output pins for process and setpoint temperatures • 3-wire RTD connection cancels lead resistance
