3. คำอธิบายผลิตภัณฑ์
The IDEC GE1A-C10-HAD24 is an electromechanical on-delay timing relay designed for industrial control applications. It features a Double Pole Double Throw (DPDT) contact configuration, a 5 Amp current rating, and operates on 24VAC. The on-delay function means that the relay contacts will change state after a set time delay once power is applied to the coil. It is typically used for sequencing operations, motor starting, and other time-dependent control tasks.

5. การติดตั้งและการตั้งค่า
5.1 การติดตั้ง
The GE1A-C10-HAD24 is designed for plug-in mounting. It typically plugs into a compatible relay socket (sold separately) which can then be mounted on a DIN rail or panel. Ensure the socket is securely fastened before inserting the relay.
5.2 การเดินสายไฟ
Refer to the wiring diagram provided with your relay socket or the product's technical datasheet for specific terminal connections. Always ensure power is off before wiring. Connect the 24VAC power supply to the designated coil terminals. Connect the load to the DPDT contact terminals according to your application requirements (e.g., normally open or normally closed configuration).
- ตรวจสอบพลังงาน: Confirm that the main power supply to the control circuit is disconnected.
- Connect Coil: Wire the 24VAC control voltage to the relay coil terminals.
- เชื่อมต่อโหลด: Wire the load circuit to the appropriate DPDT contact terminals (Common, Normally Open, Normally Closed).
- การเชื่อมต่อที่ปลอดภัย: ตรวจสอบให้แน่ใจว่าการเชื่อมต่อสายไฟทั้งหมดแน่นหนาและปลอดภัย เพื่อป้องกันการหลวมของหน้าสัมผัสและอันตรายที่อาจเกิดขึ้น
- Double Check: Before restoring power, visually inspect all wiring for correctness and ensure no bare wires are exposed.
6. การดำเนินการ
6.1 การเปิดเครื่อง
Once the relay is correctly installed and wired, restore power to the control circuit. The green 'POWER' LED indicator on the front panel should illuminate, indicating that the relay is receiving power.
6.2 Setting Time Delay
The time delay is set using the large rotary dial and the smaller 'RANGE' switch on the front panel. First, select the desired time range using the 'RANGE' switch (e.g., seconds, minutes). Then, rotate the large dial to set the specific time value within that range. The relay will initiate the timing sequence when power is applied to the coil, and the contacts will switch after the set delay.
6.3 Output Status
The red 'OUT' LED indicator on the front panel illuminates when the relay contacts have switched state after the set time delay. This provides a visual confirmation of the relay's output status.
7. การบำรุงรักษา
The IDEC GE1A-C10-HAD24 timing relay is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.
- การทำความสะอาด: Keep the relay free from dust and debris. Use a soft, dry cloth for cleaning. Do not use solvents or abrasive cleaners.
- การตรวจสอบ: Periodically inspect the relay and its connections for any signs of damage, discoloration, or loose wiring. Ensure the relay is securely seated in its socket.
- การตรวจสอบสิ่งแวดล้อม: Verify that the operating environment remains within the specified conditions (temperature, humidity, absence of corrosive substances).
- การทดแทน: If the relay shows signs of malfunction, inconsistent timing, or physical damage, it should be replaced by a qualified technician.
