The relay module (Relay Module Board)
The relay module is in the relay based on the increase of the electronic control circuit, is the use of semi finished circuit board low voltage control of high voltage to the circuit board, which is provided to user.
The use of the relay module advantage is that you can reduce the design of relay module control circuit, so that developers and designers focus on the design of the whole system function realization.
Product classification:
1, the relay module according to the control voltage classification, common types are 3.3V 5V 9V 12V 24V.
2, the relay module according to the polarity control voltage can be divided into control, high level, low level control, level control is not restricted.
3, the relay module according to whether completely isolated and divided into non isolated and isolated type. Complete isolation is generally carried out by optical coupling isolation, use completely isolated relay more secure, but due to increase in some isolated components, the price will be slightly higher.
4, according to the relay module uses a relay is divided into contact, contact type and non-contact type. Non contact type relays in any case will not produce sparks, and contact type if the seal is not good or seal failure, can produce a spark.
