XBC-DR64H/DC

Description

H-class compact CPU with 32 DC inputs + 32 relay outputs (64 local points with isolated relay outputs for many channels), 24 VDC variant and high-speed features.

The Polar Energy Assessment:

The XBC-DR64H/DC combines H-family performance with a large set of relay outputs (32 DI / 32 RO), giving you the speed of the H-type plus substantial isolated switching per slot. It is intended for applications that must switch many isolated pilot loads directly while keeping fast logic, counters and PID on the same compact CPU.

Pros

• Large number of isolated relay outputs in a single compact CPU.
• H-class speed and functional blocks (PID, HSC) available alongside isolated outputs.
• Reduces need for separate relay racks or external contactors for many pilot circuits.

Limitations

• Relay wear and life limited compared with solid-state outputs; plan maintenance for high-cycle points.
• Heavier terminal density and larger current draw when many coils are switched; before purchase, check power and backplane limits.

Typical use cases

• Small plant panels and machines where isolated outputs are required; e.g., HVAC valves/actuators, pilot contactors, alarm and annunciation circuits, plus any system that benefits from H-class scan speed.
