XBC-DR32H/DC

Description

H-class compact CPU with 16 DC inputs + 16 relay outputs, 24 VDC supply option, ~15Kstep memory and high-speed features for moderate I/O + isolated output needs.

The Polar Energy Assessment:

The XBC-DR32H/DC is a high-performance compact controller offering a relay-output local card (16 DI / 16 RO) in the XBC H family. It’s meant for applications that need the H-family speed and functionality (fast counters, PID, multiple comm ports) but also require relay outputs for AC pilot switching or isolated actuation. The H-type datasheets and reseller pages list the DR32H/DC configuration, program memory and expansion capability.

Pros

• Relay outputs provide galvanic isolation for AC pilot loads and contactor coils.
• H-class CPU performance with PID and fast counters.
• Compact, with expansion slots if you need more I/O.

Limitations

• Relays have limited mechanical life under high cycle rates; not ideal for very frequent switching without consideration.
• Lower local transistor-output speed characteristics for pulse outputs compared with transistor DO variants.

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.
