FAQ

Q: Can this module be installed outdoors?
A: No, CMA141 has IP20 protection and must be mounted inside an enclosed cabinet.

Q: Is it compatible with non-ABB PLC systems?
A: While designed for ABB systems, it can be used with other platforms if terminal voltage/current requirements match.

Q: Can multiple modules be combined for larger installations?
A: Yes, multiple CMA141 units can be linked to expand terminal capacity beyond 16 points.

Comparison with Similar Modules
Compared with ABB CMA142 (32-point version), CMA141 offers a smaller footprint suitable for compact panels while maintaining 10 A per terminal current handling.
