XGB-E04A

Description

Compact expansion chassis that accepts up to 4 XGB I/O modules, used to increase local I/O without adding another CPU. Thin, DIN-friendly footprint and connector bus for easy stacking to a main base.

The Polar Energy Assessment:

The E04A is a 4-slot extension base for the LS/XGB modular PLC family, offering a small, low-cost way to add four additional I/O or specialty modules to an existing CPU base. It connects to the main base via the system connector, follows XGB mechanical mounting and power rules, and is specified for typical industrial ambient ranges so it fits straight into machine panels.

Pros

• Small footprint, good when you only need a few extra modules.
• Simple connector bus interface, same form factor as other XGB expansion bases.
• Low weight and easy mounting for tight panels.

Limitations

• Only 4 slots; if you underestimate I/O you’ll be back ordering.
• Requires correct mating to the main base and compatible cable accessories.

Typical use cases

• OEM panels that occasionally need a handful of extra I/O channels.
• Adding a small analog block or a temperature/relay module without changing the main rack.
