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

- Model Naming Convention
| Part | Significado |
| BMX | Modicon X80 series identifier |
| DRA/DRC | Discrete relay output module (DRA = single contact, DRC = double contact) |
| 8月16日 | Number of channels (08 = 8 canais, 16 = 16 canais) |
| 05/04T/15 | Function code (05 = standard, 04T = 100~150V DC dedicated, 15 = high isolation) |
| H | Suffix for Hardened / Harsh Environment version |
- Selection Advice
- Channel Count: Choose 8 channels for small systems, 16 channels for medium systems; mixed use improves flexibility.
- Adaptabilidade Ambiental: H‑type hardened modules must be used if temperature exceeds 0°C~+60°C or special environmental stresses exist.
- Contact Type: Choose DRA series (NÃO) for simple on/off control; choose DRC series (NÃO/NC) for switching control.
- Load Characteristics:
Normal loads (≤2A): all models suitable
Heavy loads (2~3A): prefer H‑type (3A rated current)
Special voltage systems: select dedicated models with matching voltage range (por exemplo, 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, facilitating system upgrade and maintenance.
