XBM-DR16S

Description

Mixed I/O base unit variant with 8 inputs (24 VDC) and 8 relay outputs; the DR16S is a compact all-in-one micro PLC that includes serial comms and common platform features. Great when you need on-board relay outputs for AC/DC switching.

The Polar Energy Assessment:

XBM-DR16S provides 8 discrete inputs and 8 relay outputs on the base unit, plus RS-232/RS-485 communications and XGB platform features (counters, PID, etc.). Relay outputs make this SKU preferable when you must switch AC loads or need galvanic isolation without adding separate relay modules. Specs and mechanical dimensions are documented in the XGB manual and product cut sheets.

Pros

• Relay outputs allow AC/DC switching and galvanic isolation for loads.
• Small, compact unit with communications and built-in functions simplifies small machine control.

Limitations

• Relay life and switching limits mean heavy loads should use contactors or external drivers.
• Lower native input count versus DN-type base units; combine appropriately per machine needs.

Typical use cases

• Small machines that require isolated switching (pilot lamps, small heaters, solenoids via relays) plus local sensing and counters.
