Chint JQX13F Electromagnetic Relay: Wide Octagonal High-Power Control Component
The JQX13F is a small-sized, high-power electromagnetic relay, not a time relay. A time relay features a delay function (delayed action after power-on or power-off), while the JQX13F is a standard electromagnetic relay that acts immediately upon receiving a signal, with no delay characteristics.
Product Features
Wide Octagonal Design: Adopts a standard 8-pin plug-in structure, facilitating easy installation and replacement.
High-Power Control: With a contact capacity of 10A, it can directly control loads such as small motors and solenoid valves.
Transparent Dust Cover: Protects the contacts and allows easy observation of the working status.
Multiple Specifications: AC and DC voltage options are available to meet different control requirements.
Status Indicator Light: Some models (e.g., JQX13FL) are equipped with LED indicator lights to display the working status.
Typical Application Scenarios
Industrial Automation: Controls the start and stop of production line equipment.
Home Appliance Control: Power switching for appliances such as air conditioners and water heaters.
Lighting Systems: Timed/remote control of street lamps and landscape lamps.
Motor Control: Power conversion in Y-Δ starting circuits (used in conjunction with time relays).
Smart Home: Control of devices such as curtains and rolling shutters.
Model Description
JQX13F(D)/[Contact Configuration][Coil Voltage][Suffix]
D: Version with indicator light.
Contact Configuration: 2Z (2NO + 2NC), 3Z (3NO + 3NC), etc. (NO = Normally Open; NC = Normally Closed).
Suffix: For example, “L” indicates a model with an LED indicator light.
Wiring Guide
1. Coil Connection
DC Coil: Distinguish between positive and negative poles, and connect to the corresponding voltage according to the markings.
AC Coil: No polarity distinction; directly connect to the corresponding voltage.
2. Contact Connection
Normally Open (NO) Contacts: Disconnected when the coil is de-energized, closed when the coil is energized.
Normally Closed (NC) Contacts: Closed when the coil is de-energized, disconnected when the coil is energized.
Example: Controlling a 220V Lighting Circuit
1. Connect the coil to a control signal (e.g., 24V DC).
2. Connect one end of the load (lamp) to the 220V live wire, and the other end to the NO contact.
3. Connect the other end of the NO contact to the neutral wire.
Purchase Recommendations
1. Select the corresponding coil specification based on the control voltage.
2. Choose an appropriate contact capacity according to the load type and power (10A is sufficient for most scenarios).
3. If status indication is required, select models with the LED suffix (e.g., JQX13FL).
4. Mounting method: Din-rail type or socket type; purchase a matching dedicated base.
Alternative for Time Relays
If a delay function is required, consider Chint’s time relay products:
JSZ6 Series: Power-on delay type, with a delay range of 0.1–3600s.
JZF Series: Multi-function time relays, supporting multiple delay modes.
Summary
The JQX13F is a reliable, general-purpose electromagnetic relay. Its “wide octagonal” design enables wide application in various control circuits. Although it is not a time relay, its 10A high-power contacts and flexible voltage specifications make it an ideal intermediate control component in electrical control systems. If a delay function is needed, please select Chint’s dedicated time relay products.
