Description
4-slot main base chassis for the GLOFA GM6 series, intended to host a CPU, power module and up to 4 functional I/O or option modules.
The Polar Energy Assessment:
The GM6-B04M is the compact 4-slot main base in the GM6 product family. It provides the backplane, CPU/power connectors and room for up to four modules, making it a neat choice for small machines and compact OEM panels where a single-rack controller is required. The GM6 family documentation lists the B04M as the 4-slot main base and specifies the standard module allocation and power/slot behavior for the series.
Pros
- Compact main base for small controllers, CPU and power local to the rack.
- Simplifies wiring and cabinet layout for compact OEM panels.
Limitations
- Limited to 4 slots; add expansion racks for larger I/O requirements.
- Check power/thermal budget when populating with power-hungry modules (analog, special modules).
Typical use cases
- Small machine controllers, local OEM panels, compact AHU drives where a single small PLC rack is preferred.
