GM4-B04M

Description

4-slot main base board for the GLOFA GM4 PLC family; holds CPU, power modules and up to 4 functional modules.

The Polar Energy Assessment:

The GM4-B04M is a 4-slot main base (primary chassis) for GM4 controllers. Unlike expansion bases, the main base accepts the CPU module, power supply module and hosts up to four I/O or option modules directly. Choose a main base when building a compact, self-contained GM4 controller (CPU + power + modules) for small machines or panels.

Pros

• Compact main base capable of hosting CPU and power modules plus up to 4 I/O/option modules.
• Ideal for small standalone controllers and compact OEM panels.

Limitations

• Slot-limited compared with larger main bases (6/12 slots); may require expansion boards for bigger systems.
• Pay attention to power budget when fitting power-hungry modules in a 4-slot main base.

Typical use cases

• Small standalone machine controllers, compact OEM control panels, and quick deploy GM4 systems where footprint and cost are priorities.
