- Seamless integration with existing MTL5000 series backplanes and power supplies
- Guaranteed interoperability with Honeywell Experion, Yokogawa CENTUM, ABB 800xA, and other major DCS platforms
- Long-term spare-parts availability through authorized distribution channels
Typical Applications
- Oil & gas upstream / downstream process control
- Chemical and petrochemical plant instrumentation
- Power generation temperature monitoring loops
- Pharmaceutical batch process control
- Water treatment and utilities SCADA systems
- Hazardous-area DCS / PLC I/O marshalling cabinets
System Compatibility
The MTL5575 is designed to interface with standard 4–20 mA analog input cards across all major control platforms:
- Honeywell Experion PKS / TDC 3000
- Emerson DeltaV / Fisher ROC
- Yokogawa CENTUM VP / ProSafe
- ABB System 800xA / AC500
- Siemens SIMATIC S7 / PCS 7
- Rockwell Automation ControlLogix / PlantPAx
- Schneider Electric Modicon M340 / Foxboro
Selection Guide
Use the following criteria to confirm the MTL5575 is the correct choice for your application:
| Selection Criterion | MTL5575 Capability |
|---|---|
| Input sensor type | Thermocouple (multi-type) or Pt100 RTD |
| Output signal | 4–20 mA (2-wire loop) |
| Hazardous area classification | Zone 1 / Zone 2 (ATEX / IECEx) |
| Mounting format | 35 mm DIN rail |
| Supply voltage | 24 V DC |
| Galvanic isolation required | Yes – input / output / supply isolated |
| HART pass-through required | No (use MTL5575H for HART) |
If your application requires HART communication, consider the MTL5575H. For non-hazardous areas, the MTL4575 may offer a cost advantage.

Replacement & Compatibility FAQ
Q: Can the MTL5575 replace an MTL4575 directly?
A: Not directly — the MTL4000 and MTL5000 series use different backplane connectors and supply voltage ranges. Verify mechanical and electrical compatibility before substitution.
Q: Is the MTL5575 suitable for SIL-rated safety loops?
A: The MTL5575 is not independently SIL-rated. For functional safety applications, consult Honeywell for SIL-capable alternatives within the MTL range.
Q: What is the difference between MTL5575 and MTL5575H?
A: The MTL5575H adds HART signal pass-through capability, allowing digital communication with HART-enabled field instruments over the same 4–20 mA loop.
Q: Can Konmask.com supply original Honeywell MTL5575 units?
A: Yes. Contact us with your quantity and delivery requirements for a prompt quotation.
Q: What certifications does the MTL5575 carry?
A: ATEX and IECEx for hazardous area use. Refer to the official Honeywell datasheet for the complete approval list.
