Selection Guide
Use the following criteria to confirm the MTL24571 is the correct model for your application:
- Supply voltage: Confirm your panel supplies 24–30 VDC to the converter rail
- Signal type: Verify input/output signal range (4–20 mA, 0–10 V, HART, etc.)
- Hazardous area: Check if ATEX / IECEx certification is required for your zone
- Channel count: MTL24571 is a single-channel device — use MTL24572 for dual-channel needs
- Mounting: Standard 35 mm DIN rail — confirm available rail space in your cabinet
- Ambient temperature: Ensure installation environment is within -20°C to +60°C
