XGB-M04A

Description

Mini expansion base with 4 module slots for XGB I/O and specialty cards. Designed to be paired with XGB main bases when additional local I/O or function cards are needed. (Verified from regional reseller pages and LS Electric form-factor docs)

The Polar Energy Assessment:

The M04A is a compact 4-slot expansion chassis that extends an XGB PLC system’s I/O capacity. Its connector interface matches the XGB bus, it mounts on DIN rail or panel, and it supports the same ambient and electrical ratings as the main base. Good fit when machine space is tight and you only need a few extra cards.

Pros

• Small footprint, keeps panel real estate low.
• Plug-and-play mechanical/electrical bus for easy integration.
• Ideal for small expansions or mixed analog/discrete module fields.

Limitations

• Only 4 slots means not enough if the machine grows fast.
• Requires terminal blocks/cables (ordered separately).

Typical use cases

• Adding a couple of analog or specialty modules to a compact machine with space constraints.
