Product Details
BF-D220A+ is widely used in temperature control applications, including hot water, solar, and heat pump systems.
One input, two outputs.Temperature measurement uses one 10K NTC thermistor sensor.
Two outputs independently control two relays (normally open contacts) for temperature control across -45℃～110℃, with special functions including [Control Hysteresis] adjustment and [Measurement Deviation] correction.
The wide-range power supply automatically adapts to AC80V–240V for stable, reliable, long-term operation.
