XBC/XEC-DP40SU

Description

SU-class compact CPU with higher local I/O (typical ≈24 DI / 16 DO), SU performance for bigger compact panels that still need PID/HSC/positioning.

The Polar Energy Assessment:

DP40SU ups the local I/O count while keeping SU performance characteristics: ~15k steps program capacity, ≈94 ns/step execution and the usual SU feature set (multi-channel HSC, PID loops, limited positioning). Good for medium-density panels that require both more inputs and the SU control feature set. As always, confirm exact DI/DO split and output type/polarity on the quote.

Pros

• Higher local I/O density in the SU tier; reduces need for immediate expansion.
• SU class features provide robust HSC/PID/positioning in one compact unit.

Limitations

• Larger I/O density increases wiring complexity and power budget planning.

Typical use cases

• AHU/chiller panels with many sensors, mid-sized OEM machines that need lots of discrete I/O plus PID/HSC, and consolidated plant zone controllers.
