Relay contacts There are three basic forms: 1. moving together type (H type): two contacts when the coil is not energized is disconnected, the power, the two contacts is closed. In co-word phonetic prefix "H" represents. 2. move off type (D type): when the coil is not energized the two contacts are closed, the two contacts after power is disconnected. With hyphenation phonetic prefix "D" indicates. 3. Conversion type (Z type) This is the type of contacts. This contact group consisted of three contacts, namely the middle is moving contact, a stationary upper and lower contacts. When the module relay coil is not energized, the movable contact and one of the stationary contacts open and another closed, the coil is energized, 24V Omron relay modules, movable contact to move into a closed off so that the original, the original closed the open state, the purpose of conversion. Such a contact group called changeover contacts. Relay module module combination relay series, from the terminal block adapter protection function, the best Omron relay module, 8 inputs, mainly for the automated control of the modular combination relay, using imported relay, the international standard Terminal station and wiring standard type relay modules now 4/8/12/16 bit relay module, 1 normally open 1 normally closed and two normally open normally closed output specifications, and the other we can be customized according to a variety of models relay modules. The relay module is based on the increase in the relay electronic control circuit, you can use low voltage control high-voltage semi-finished circuit boards, in the form of a circuit board to the user. The advantage of using the relay module relay module can reduce the control circuit is designed so that designers will develop more energy to achieve the design features of the system. Classification according to the control voltage relay module, common types of 12V 24V. Relay module in accordance with control voltage polarity can be divided, high-level control, low level control, does not limit the level control. The relay module is completely isolated and divided according to whether not isolated and totally isolated. Completely isolated are generally carried out by opto-isolation of using fully isolated relay safer, Omron relay modules, but due to increased number of isolated components, the price will be slightly higher. The relay module relay if there is contact, Omron relay module block, divided into contact type and non-contact type. Non-contact type of the relay in any case will not produce sparks, while if the seal is not good or seal failure, it will produce contact type of spark.
