Product Details
C-440 provides two independent temperature-control channels, each with a dedicated NTC 10K thermistor temperature sensor for independent temperature measurement and output control; Channel 1 temperature control relay output has NO and NC contacts; Channel 2 has NO contacts.
Can measure temperatures from -50.0 to 150.0°C and provide constant-temperature control between -20°C and 120°C.Temperature measurement deviation correction compensates for measurement errors.
The switching power supply automatically adapts to AC80V～240V input, providing stable, reliable, and durable operation.
