Description
Product Introduction
The REO REOTRON 567LH-DP24 is a robust micro-controller-driven power regulator built for process automation systems that demand precise, stepless AC power output control. Utilizing internal semiconductor thyristors, the unit converts fixed-frequency line voltage into a fully adjustable RMS output voltage tailored for resistive/inductive industrial loads and vibratory bowl feeders.
The part designation 567LH-DP24 breaks down into the 567-series power control platform, Phase-Angle Drive mode (LH), an integrated PROFIBUS-DP communication module (DP), and a 24 Amp continuous load current rating (24). Installing a pre-tested 567LH-DP24 controller resolves erratic feeder bowl amplitudes, eliminates thermal drift in industrial ovens, and restores missing PROFIBUS network drops.

Application Scenarios & The “Trench” Experience
In automated packaging lines, electromagnetic vibratory feeders use phase-angle controllers like the 567LH-DP24 to precisely meter small parts or food products into weigh hoppers. If the main thyristor firing circuit degrades or the PROFIBUS controller node loses sync, the feeder bowl either surges violently—spilling product across the line—or stops feeding altogether, causing an upstream machine fault lock.
Replacing the damaged controller with a tested REOTRON 567LH-DP24 unit restores smooth, soft-start amplitude ramping and re-establishes fieldbus setpoint control from the master PLC within minutes.
Typical Applications:
- Industrial Vibratory Feeders – Tuning vibration frequency and stroke amplitude on heavy material transfer bowls and conveyors.
- Industrial Electric Heating – Phase-angle power regulation for infrared drying tunnels, injection molding nozzles, and heat-treating furnaces.
- Transformer & Inductive Load Control – Soft-starting primary windings on large step-down industrial transformers.

Transparency SOP: Quality Assurance & Testing
Every surplus or reconditioned REOTRON 567LH-DP24 unit goes through a rigorous 5-stage bench test protocol before shipment:
- Visual & Internal Component Inspection: High-magnification check of SCR power modules, trace integrity, internal bus bars, and electrolytic filter capacitors.
- Logic & Fieldbus Boot Test: 24V DC logic power-up check verifying firmware initialization, status LEDs, and PROFIBUS station address DIP-switch responses.
- Phase-Angle Waveform Verification: Oscilloscope audit across the output terminals while adjusting 0–10V analog and fieldbus setpoints to ensure clean SCR firing symmetry.
- Full-Load Thermal Burn-In: 4-hour dynamic load test at maximum 24A current rating to verify heatsink thermal dissipation and overcurrent protection logic.
- ESD Cleaning & Packaging: Cleaned, terminal screws torqued, sealed in anti-static protective bags, and foam-encapsulated for shipping protection.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Verify PROFIBUS Node Termination: When replacing a DP-series unit on a daisy-chained fieldbus line, ensure the DB9 connector’s bus termination resistor is set correctly (ON if it is the last device on the segment, OFF if the network continues to other nodes).
❗ Set Correct Load Type Jumpers: Phase-angle control behaves differently on purely resistive loads (heaters) versus inductive loads (electromagnetic vibratory coils). Ensure the internal parameter profile or jumpers match your specific load type to prevent current spikes and blown thyristor fuses.
⚠️ Proper Heat Sink Ventilation: The 567LH-DP24 generates internal heat proportional to load current. Mount the unit vertically inside control cabinets with at least 100mm (4 inches) of clearance above and below the heatsink fins for natural or forced-air cooling.
Frequently Asked Questions (FAQ)
Q: What does the “DP” suffix mean in 567LH-DP24?
A: The “DP” designation indicates that the unit is equipped with a PROFIBUS-DP industrial fieldbus interface for remote setpoint, enable, and diagnostic control.
Q: Can this unit operate with standard analog control signals if PROFIBUS is not used?
A: Yes. The controller includes onboard terminal blocks supporting standard analog setpoint signals (0–10V DC or 4–20mA) and contact-closure enable lines.
Q: Is the 24A rating maximum surge or continuous?
A: The 24A rating represents the maximum continuous RMS current capacity when mounted according to manufacturer cooling specifications.
Q: What warranty is provided with this surplus unit?
A: Every surplus and reconditioned REOTRON 567LH-DP24 module is backed by a full 12-month operational warranty. If the unit experiences SCR breakdown, signal drift, or fieldbus communication failure within 365 days, we replace it or issue a full refund.
