3. Application Differences

4. คำแนะนำในการคัดเลือก
5. Environment First Principle: BMXDRA1605H must be selected if operating temperature exceeds 0~60°C, or there is risk of corrosive gas, ฝุ่นหนัก, or mold growth.
6. Load Capacity: For loads up to 3A, the H version provides higher current margin and more reliable long‑term operation.
7. Cost Balance: The standard version (BMXDRA1605) is lower‑cost and offers sufficient performance in normal environments with better cost‑effectiveness.
8. ความเข้ากันได้: Both modules are fully compatible with Modicon M340/M580 PLC systems and X80 racks. They can be directly interchanged without program modification.

2. Detailed Technical Parameter Comparison

3. คุณสมบัติที่สำคัญ & Applications by Model

3.1 BMXDRA0805 Series (8‑channel Standard)

BMXDRA0805: Basic 8‑channel NO relay output for normal industrial environments (0°C~+60°C), เช่น, โซลินอยด์วาล์ว, contactors on production lines.

BMXDRA0805H: Harsh environment hardened version, same functions as BMXDRA0805, stable at -25°C~+70°C, tested against corrosion, ฝุ่น, fungi, salt spray; ideal for chemical, marine, โลหะวิทยา.

3.2 Special‑Purpose 8‑Channel Models

BMXDRA0804T: All‑climate (TC) โมดูล, dedicated for 100~150V DC systems, for industrial equipment with special power supplies.

BMXDRA0815: High‑isolation 8‑channel NO relay output with wider DC voltage range (24~125V DC), better isolation for precision equipment control.

BMXDRC0805: Only model with NO/NC (พปส) ผู้ติดต่อ, one channel with both NO and NC; suitable for complex switching control circuits.

3.3 BMXDRA1605 Series (16‑channel Standard)

BMXDRA1605: Basic 16‑channel NO relay output, 8 groups with shared common terminals, for medium‑to‑large automation systems such as assembly lines and HVAC.

BMXDRA1605H: Harsh environment hardened version, same functions as BMXDRA1605, -25°C~+70°C wide temp, 3จัดอันดับปัจจุบัน (higher than standard), stronger load capacity for outdoor/unconditioned panels.

5. คำแนะนำในการเลือก
6. Channel Count: เลือก 8 channels for small systems, 16 channels for medium systems; mixed use improves flexibility.
7. การปรับตัวด้านสิ่งแวดล้อม: H‑type hardened modules must be used if temperature exceeds 0°C~+60°C or special environmental stresses exist.
8. ประเภทการติดต่อ: Choose DRA series (เลขที่) for simple on/off control; choose DRC series (ไม่ใช่/ NC) for switching control.
9. Load Characteristics:

Normal loads (≤2A): all models suitable

Heavy loads (2~3เอ): prefer H‑type (3จัดอันดับปัจจุบัน)

Special voltage systems: select dedicated models with matching voltage range (เช่น, BMXDRA0804T for 100~150V DC)

All models are fully compatible with Modicon M340/M580 PLC systems and X80 racks. Direct interchange is supported without program changes, อำนวยความสะดวกในการอัพเกรดและบำรุงรักษาระบบ.
