Typical Applications
Compact 6-channel Heating Control
For ovens, packaging machinery, molds and small multi-zone equipment with six centrally controlled single-phase branches.
Modular Equipment Integration
For repetitive multi-loop heating units, easing OEM integration and maintenance.
Zoned Resistance Heating
For resistance wire, far-infrared and auxiliary heating zones; confirm each branch’s parameters independently.
FAQ
SMART-6 or ZERO-6?
Both are 6-channel integrated single-phase controllers; they differ in control supply, interfaces and functions — confirm per project.
Suitable for ovens and mold heating?
Yes for 6-zone single-phase heating; verify per-zone power, current, temperature control and continuous duty.
Can the six channels start/stop independently?
Start/stop and control per channel depend on the model, external signals and system logic.
How to size each channel’s current?
Base it on the branch’s maximum operating current, considering start-up, ambient rise and long-term continuous duty.
Does a single-channel fault affect the others?
Per-branch protection and control logic limit the impact; isolation depends on wiring, protection scheme and fault type.
