XBC/XEC-DN64H

Description

High-performance H-class compact PLC with 32 DC inputs + 32 transistor outputs, fast scan and up to 10 expansion slots for larger I/O systems.

The Polar Energy Assessment:

The XBC/XEC-DN64H is an H-type XGB compact CPU designed where speed and I/O density matter. It typically ships with 32 DI and 32 DO (transistor), ~15k step program capacity, H-class execution rates (H family ~83 ns/step) and support for up to 10 expansion modules to reach high total I/O counts. Use it when you need fast logic, robust high-speed counters, floating point/PID and a compact footprint.

Pros

• High local I/O density (64 points) reduces need for external racks.
• H-class speed and features: fast counters, PID, floating point.
• Up to 10 expansions for scalable architectures.

Limitations

• Transistor outputs only; not for switching mains without relays/contactors.
• Dense terminals need careful wiring and panel planning.

Typical use cases

• AHU/chiller local controllers with demanding loops, packaging and motion lines that use multiple fast counters, mid-size machine centers where compact high performance is needed.
