MIVII1000E00HI00 GE Universal relay
First, the relay structure
Although the operation principle and structural form of relays are different, they are composed of the following three parts:
1, induction MIVII1000E00HI00 mechanism (accept input signal) : can reflect a certain input variable (such as current, voltage,
power, impedance, frequency, temperature, pressure, speed, light, etc.) induction mechanism (input part), input loop.
2, comparison mechanism (to provide comparison) : between the input part and the output part of the relay, there
are coupling and isolation of the input, function processing and the output part of the intermediate mechanism (drive part)
3, the actuator (output switching signal) : can achieve the controlled circuit “on”, “off” control of the actuator (output part), output loop.
Relays generally refer to MIVII1000E00HI00 electromagnetic relays, that is, the kind of mechanical action. The essence of the role of the relay
is to use a loop (generally small current) to control the on-off of another loop (generally large current), and in this
control process, the two loops are generally isolated, its basic principle is to use the electromagnetic effect to control
the mechanical contact to achieve the purpose of on-off. The coil with an iron core is energized, the coil current generates
a magnetic field, and the magnetic field absorbs the armature to break the contact. The whole process is a process of “small current – magnetic – mechanical – large current” [2].

Second, the form of relay contact
1. Dynamic closing type (H type) : The two contacts are disconnected when the coil is not powered on, and the
two contacts are closed after the power is turned on. It is represented by the alphabetic prefix “H”.
2. The breaking type (D-type) coil is not MIVII1000E00HI00 powered on when the two contacts are closed, and the two contacts are
disconnected after the power is powered on. It is denoted by the phonetic prefix “D”.
3. Conversion type (Z type) This is the contact group. This contact group has a total of three contacts, that is, the
middle is a moving contact, the upper and lower one static contact. When the coil is not powered on, the moving
and one of the static contacts are disconnected and the other is closed, and after the coil is powered on, the
moving contact moves to make the original disconnected into a closed state, and the original closed into a disconnected
state to achieve the purpose of conversion. Such a group of contacts is called a transfer contact. It is represented by the pinyin prefix “z” of the word “turn”
