Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents to the DSE6120 MKIII. Always verify electrical and communication compatibility before substitution:
- DSE6110 MKII — Previous generation DSE AMF module; same form factor, fewer I/O points
- DSE6020 — Entry-level AMF module; suitable for simpler single-generator applications
- DSE7310 MKII — Upgrade path; adds SCADA/Modbus RTU support for networked installations
- ComAp InteliLite 4 AMF 20 — Third-party equivalent; compatible wiring but requires re-parameterization
- Deif GPC-3 Series — Industrial-grade alternative; suitable for marine and heavy-duty applications
- Smartgen HGM6120 — Cost-effective OEM equivalent widely used in Chinese-manufactured gensets
Note: Konmask.com recommends using genuine DSE6120 MKIII for warranty-critical and safety-critical installations.

Selection Guide
Use this guide to confirm the DSE6120 MKIII is the right module for your application:
- Single generator, AMF only? → DSE6120 MKIII is the optimal choice
- Need load sharing or parallel operation? → Consider DSE8610 MKII or DSE8620 MKII
- Need Modbus RTU / Ethernet? → Upgrade to DSE7310 MKII or DSE7320 MKII
- Budget-constrained, non-critical application? → DSE6020 or Smartgen HGM6120 may suffice
- Replacing DSE6110 MKII? → DSE6120 MKIII is the direct MKIII upgrade; same cutout dimensions

Replacement & Compatibility FAQ
Q: Is the DSE6120 MKIII a direct replacement for the DSE6110 MKII?
A: Yes. The MKIII shares the same panel cutout (180 × 116 mm) and connector layout. Re-parameterization via DSE Configuration Suite is recommended after swap.
Q: Can the Smartgen HGM6120 replace the DSE6120 MKIII?
A: Functionally similar for basic AMF applications, but the HGM6120 lacks DSE’s configuration software ecosystem and some advanced protection features. Suitable for non-critical OEM genset panels.
Q: Does the DSE6120 MKIII support Modbus?
A: No. The DSE6120 MKIII uses RS-232 for PC configuration only. For Modbus RTU support, select the DSE7310 MKII or higher.
Q: What is the difference between DSE6120 MKII and MKIII?
A: The MKIII adds enhanced LCD display, improved EMC performance, and expanded configurable I/O compared to the MKII.
Q: Can I use the DSE6120 MKIII for a three-phase mains supply?
A: Yes. The module supports single-phase and three-phase mains sensing configurations.
