DZK-100T series intermediate relayDetailed product description：

Application of DZK-100T series intermediate relay

The DZK-100T series fast intermediate relay is used in various protection and automatic control circuits for DC operation to expand the control range.

Meaning of Model 2


3 Working principle and structure
3.1 This relay adopts a protruding installation, and the main body is a plug-in structure.
3.2 The main body of the DZK-100T series fast intermediate relay is the same as that of the DZK-100 series relay
3.3 The DZK-100T series fast intermediate relay is equipped with a mountain shaped snap on electromagnetic mechanism, with the coil located on the column. The relay consists of five parts: mountain shaped iron column, coil, armature, bracket, and contact system.
3.4 In order to reduce the power consumption and temperature rise of the relay, additional resistors are added in series in the relay voltage winding circuit.
When the coil of the relay is energized, there is current flowing through the coil, which magnetizes the iron core and attracts the armature. When the coil is de energized, the magnetic force is consumed and the armature is released. The movement of the armature drives the support plate of the spring, causing the spring contacts to be attracted and disconnected accordingly.
The internal wiring diagram of the DZK-100T series fast intermediate relay is shown in Figure 1.
The appearance and installation dimensions of the DZK-100T series fast intermediate relay are shown in Figure 2.

4.2 Action value and hold value
4.2.1 The operating voltage and holding voltage should be between 50% and 70% of the rated voltage.
4.2.2 The operating current and holding current shall not exceed 80% of the rated current.
4.3 Return value: not less than 5% of the rated value.
The operating time of the relay at rated voltage and rated current shall not exceed 15ms.
In an AC circuit with a voltage not exceeding 220V and a current not exceeding 5A, the relay contacts have a breaking power of (COS Φ=0.4) 500VA. The contact of the relay device in a DC circuit with a voltage of 220V and a current not exceeding lA can disconnect a DC inductive load (T=5 × 10-3S) of 50W.
4.6 The electrical life of the relay at rated capacity is 104 times.
4.7 Power consumption of relays
4.7.1 Voltage coil power consumption of relay at rated capacity
Relays without self-protection current coils have a voltage coil power consumption of no more than 3W.
Relays with self-protection current coils have a voltage coil power consumption of no more than 8W.
4.7.2 The power consumption of the self-sustaining coil at rated current shall not exceed 3W.
4.8 DZK-110T type relays are long-term energized products, while relays with self protective coils are short-term energized products.
