Current relay is an electronic control device that has a control system (also known as input circuit) and the control system (also known as output circuit). It is usually used in automatic control circuits.A "automatic switch" with a large current.Therefore, automatic adjustment, security protection, and conversion circuits are played in the circuit.

Current relay settled
Fixed error 1. If the absolute value of its average error is generally less than or equal to three % within the range of the fixed value.Average error = 5 measurement average-set value ÷ set value × 100%2. Under standard conditions, the maximum and minimum value of the 5 movement values ??measured on the same setting value should be less than or equal to 4%.3. At -10 ° C-50 ° C, the absolute value of any fixed-point error is less than 5 % of the fixed value.4. In the range of 80-110%of the auxiliary voltage, the absolute value of the setting error of any setting value should be less than 4%.5. 1.1 times the action time of the fixed value is less than or equal to 30ms; the action time of the two times the fixed value is not more than 20ms.
Current relay model
The first part of the relay model uses letters to represent the main type of relay.JR ——Long power relay JZ —— medium -power relay JQ —— high -power relay JC — magnetic electrical relay JU — heat relay or temperature relay
The role of current relay
There is a gap between the moving tablets in the current relay and the magnetic pole. We must ensure that the current relay is in any working state, and the moving piece and magnetic pole of the current relay cannot be bumped. The current relay is used.Should not lubricate the bearing of the current relay, when the contact of the cleaning current relay is suitable for using a blade of blade or fine grinding stones, and then wipe the clean and soft cloth to avoid the contact of the current relay of the current relay in the finger.Remember not to use sandpaper or other rough things to clean the contacts of the current relay.
