Constant Temperature and Humidity Control Mainboard
When the box temperature is high over that of preset (highthreshold ) ,the relay shut up, the ACC220V power input isdisconnected ,whole System stop working, when temperaturedown below that of preset (high threshold) over 5°C,the relayopen ,the system return to work.
When the box temperature is down below that of preset (lowthreshold ) ,the relay shut up, the ACC220V power input isdisconnected ,whole System stop working, when temperatureascend high over that of preset (low threshold) over 5°C,the
relay open ,the system return to work.
Temperature-controlled motherboard for outdoor projector waterproof enclosures
When the box temperature or below that of presetthe Relay shut up ,the heating device start to work.When the box temperature high that of presetOver 5 C,the relay open ,the heating device stop
working.
When the box humidity high over that of preset,The relay shut up ,the heating device start to workwhen the box humidity low below that of preset,the relay open ,the heating device stop working
The temperature control mainboard integrates RS-485 and serial communication interfaces, supporting remote parameter reading and configuration. It is widely used in outdoor advertising systems, charging stations, base stations, and temperature monitoring applications.
