Coil Characteristics:

– Powered by 24V DC, with a power consumption of approximately 0.9W, the operating time ≤ 20ms, and the release time ≤ 20ms.

– A freewheeling diode (for DC models) is built-in to suppress the reverse electromotive force when the coil is powered off.

Environmental Adaptability: The working temperature is from -25°C to +55°C, the humidity ≤ 90% (without condensation), and the protection level is IP20.

วิธีการติดตั้ง: Plug-in structure, supporting 35mm rail installation or screw fixation. The matching base model is CZY14A (14 หมุด).

1. Application Scenarios and Functions
2. การใช้งานทั่วไป

ระบบอัตโนมัติทางอุตสาหกรรม: Used for the amplification and isolation of PLC output signals, controlling loads such as solenoid valves and contactors.

Power System: As a signal relay, it realizes functions such as relay protection and alarm indication.

Equipment Control: Realizes the logical switching of multiple sets of circuits in machine tools and production lines.

2. คุณสมบัติการใช้งาน

Multi-contact Design: Four sets of independent contacts can control multiple loops simultaneously, reducing the number of relays.

Status Indication: The model with a light (with the D suffix) can intuitively display the on-off status of the coil through the LED, which is convenient for troubleshooting.

High Reliability: The silver alloy contact material has strong arc resistance, and the mechanical life reaches more than 10^7 times.

III. คู่มือการเดินสายไฟและการติดตั้ง

1. Pin Definition

ขั้วต่อคอยล์: หมุด 13 และ 14 are connected to the 24VDC power supply (pay attention to the positive and negative polarities).

Contact Terminals:

– Each set of contacts includes a common terminal (COM), เปิดตามปกติ (เลขที่), and normally closed (เอ็นซี). ตัวอย่างเช่น:

– 42 (COM), 82 (เลขที่), และ 43 (เอ็นซี) are the first set of contacts.

– For the specific pin arrangement, refer to the markings on the relay housing or the instruction manual.

2. Wiring Example

Basic Control Circuit: Control the relay coil through a button, and then drive the indicator light or load with the contacts. ตัวอย่างเช่น:

– One end of the button is connected to the positive pole of the 24VDC power supply, and the other end is connected to pin 14 of the coil. เข็มหมุด 13 of the coil is connected to the negative pole.

– One end of the indicator light is connected to the positive pole of the power supply, the other end is connected to the NO contact (เช่นพิน 82), and the COM (เช่นพิน 42) is connected to the negative pole of the load.

3. Installation Precautions

Vibration Prevention: In a vibrating environment, it is recommended to use rail clips or screws for reinforcement.

Wire Specification: It is recommended to use multi-strand flexible wires with a cross-sectional area of 0.5-1.5mm² to ensure reliable connection.

Heat Dissipation Requirements: Avoid dense installation in a high-temperature environment, and reserve at least 10mm of heat dissipation space.

1. Price and Supply
2. Market Quotation

Model with Light (with D suffix): ประมาณ 15-30 yuan per piece (on domestic e-commerce platforms), and it can be lower than 10 yuan per piece for bulk purchases.

Model without Light: ประมาณ 8-15 yuan per piece, and the specific price varies depending on the packaging (เช่น 20 ชิ้นต่อกล่อง) and the channel.

2. Supply Status

Conventional Model: The 24VDC version is a mainstream specification and is usually available in stock.

Special Requirements: For the version with a light or customized pins, it is necessary to confirm the inventory in advance, and some distributors can provide fast delivery services.

1. Alternative Models and Compatibility
2. Alternatives of the Same Brand

JZX-22F/4Z (without D suffix): It has the same function but lacks a status indicator light, suitable for scenarios with limited budgets.

JQX-13F series: It is a large-current model (such as 5A contacts), suitable for high-load control.

2. Cross-brand Alternatives

Omron G2R-1 series: Four sets of contacts, 24VDC coil, and the pin definitions are compatible, which can be directly replaced.

Schneider LC1D series: Pay attention to the differences in pin arrangements, and it is recommended to refer to the wiring diagram for confirmation.

1. Genuine Product Verification and Purchase Suggestions
2. Genuine Product Identification:

– The packaging should have a Chint anti-counterfeiting label, and the silk printing on the product surface should be clear without burrs.

– The serial number can be queried for authenticity through the Chint official website or customer service.

2. Purchase Channels:

Overseas Users: Purchase through the platform of www.transformerandswitchgear.com (such as wa: 86-13811255435).

ปกเกล้าเจ้าอยู่หัว. ข้อควรระวัง

1. Coil Voltage Matching: Strictly distinguish between the AC/DC versions to avoid burning the coil due to incorrect connection.
2. Contact Load Limitation: For resistive loads (such as heaters), it can be close to the rated current, and for inductive loads (such as motors), it needs to be derated to less than 50%.
3. Electromagnetic Interference Protection: In a high-frequency environment, it is recommended to use shielded cables, and connect an RC absorption circuit in parallel at both ends of the contacts.

It is recommended that users select the model with or without a light according to specific requirements and obtain the latest manual through official channels. If complex control logic is required, it can be matched with Chint PLC (such as the NICE series) to achieve automated integration.
