The role of price high and low temperature solid state relay

　　high and low temperature test chamber price, although the intermediate relay specification model on the sales market varied, but most of their principles are similar. Key, optocoupler circuit and an output (load) of the power supply circuit is constituted by three type portion (manipulating) the power supply circuit.

　　Type power supply circuit Linpin price high and low temperature intermediate relay, for manipulating the data type signal to produce a control loop to make it into a video signal relay opening. Type power supply circuit common DC intermediate relay type, some type of communication. DC type power supply circuit is divided into a resistive type and a constant current type. Resistive type power supply circuit with current manipulation type of typing a forward voltage change linearly. Constant current type power supply circuit when the voltage exceeds must type value, no longer with increasing the amount of current operating voltage is significantly enlarged, the relay such vehicles is applicable to a very wide operating voltage type category.
　　High and low temperature price relay output power supply circuit is opened under the manipulation of the data signal, remains turned convert the intermediate relay. Power output from an output circuit key components (integrated IC) and starting transient antagonism absorbing control loop configuration, and sometimes further comprises a feedback circuit.
　　Linpin small series production of a high temperature chamber, temperature and humidity chamber may G code, the key walk test chambers Formula adjustment value of the heat pipe and heat pipe with a humidifier TEMI880 with temperature and humidity control relay. PID + relay price remains high and low temperature in accordance with temperature and humidity stable.
