XBC/XEC-DP60SU

Description

SU-class compact main unit with high local I/O density: typically 36 DI + 24 transistor outputs, SU performance (≈15k step program memory, ~94 ns/step).

The Polar Energy Assessment:

The DP60SU is the SU (standard) tier main unit in the XGB/XBC family intended for medium-to-large compact panels that require significant local I/O with professional control features. It pairs the SU performance tier (fast scan, PID, robust high-speed counter and positioning support) with a 60-point class local I/O layout so many plant-zone or applications avoid external expansion. Catalogs list program memory ≈ 15K steps and SU processing speeds around 94 ns/step; max I/O and expansion stages follow XGB expansion rules.

Pros

• High local I/O density reduces need for additional racks.
• SU performance: fast scan, PID, HSC and positioning capability in a compact form.
• Good expansion headroom per XGB family rules.

Limitations

• Dense terminals increase wiring complexity and power/thermal planning requirements.
• Transistor outputs (no relays) require external contactors/relays to switch mains loads.

Typical use cases

• Medium-density AHU/chiller zone controllers, packaging machines with many discrete I/O and counters, mid-size panels that need PID/HSC but want a single compact rack.
