JL-6A,JL-6C type current relayDetailed product description：

Purpose:
The JL-6 series integrated circuit current relay is a static, non directional, transient, AC current relay. Can be used as a starting element in power system transmission lines, motors, overload and short circuit protection. Relays are not sensitive to the DC component in short-circuit currents, so they can be used in lines that require small transient exceedance. This relay is composed of an integrated circuit to form an execution circuit, which has the characteristics of high sensitivity, fast action speed, low power consumption, and easy setting. The DC power supply and outlet relay of the relay are monitored by signal indicator lights, and the outlet relay has 2 sets of large capacity conversion contact outputs. Users can directly control the protected equipment according to specific situations (except for JL-6A). The relay action value is set by the dial switch on the panel, which is intuitive and convenient.

Relay model name:

Working Principle:
The input current is converted into an appropriate voltage by a current voltage converter, and through the setting of the operating value and active bandpass filtering, it undergoes full wave rectification. The pulsating voltage is compared and integrated, and the detector determines the integration level horizontally. When the integration level exceeds the detection level, the detector outputs a high level to drive the output relay to operate. This relay adopts a new type of integral judgment circuit, which makes the action time and return time of the relay fast, and the transient overshoot is also small, with strong anti-interference performance.

Usage:
To use the JL-6C, 6A model, please carefully observe the panel of this relay. The four speed ID setting switch in the upper left corner is used for rough adjustment of the relay's current value. For example, if you have a relay with IN=5A in your hand, you can obtain the setting values of 0.1IN, 0.2IN, 0.4IN, 0.8IN, 1IN, 2IN, 4IN, and 8IN through the ID switch (see the figure below). If it cannot meet your needs, please use the MN dial switch in the lower left corner for fine adjustment. Please calculate according to the formula I=ID (1. MN) on the panel. The calculation method is as follows: If IN=5A, you need the operating current IN=15A. You can first set the ID to 2IN=10A, and then calculate M=5 and N=0 through the formula. After setting according to the above method, when the applied current I=15A, the right indicator light changes from green during normal operation to red, and the relay acts.

Wiring diagram behind the relay:
The wiring diagram on the back of the relay is shown in Figure 1 (the contacts in the diagram are the state when the relay is in a power-off state without applying DC voltage and AC voltage. When the relay is applied with DC auxiliary voltage but the AC voltage is zero, the contact state of the overvoltage relay is the same as that in the diagram, while the contact state of the low current relay is exactly the opposite).

Refer to Figures 2 and 6 in the protruding modular insertion structure.
