UNITEC

Unitec control and protection components for panels and machine cells

Unitec supplies core building blocks for low-voltage panels, machine control, and retrofit programs. The range helps engineering and maintenance teams standardize on reliable coil behaviour, clean wiring, and predictable service life under European conditions.

Unitec automatics and control selection for panel builders and OEMs

Scope contactors, motor starters, interlocks, and interface modules in unitec automatics and control. Match device families across coil voltages, auxiliary contact layouts, and mounting formats to keep spares lean and assembly fast.
Key checks: utilization category AC 3 or AC 4, mechanical and electrical endurance, coil inrush and holding power in warm panels, creepage and clearance for enclosure pollution degree, IP rating, ambient limits, and EMC immunity near VFDs.

Unitec relays for clean PLC interfacing and load switching

Use unitec relays for signal isolation, voltage level translation, and reliable actuation of solenoids, lamps, or small motors. Select contact metallurgy for the load type, verify bounce and release times for PLC inputs, and choose sockets with retention springs and test buttons for commissioning.
Spec points: contact arrangement, dielectric strength, coil suppression, indicator LEDs, and identification accessories for dense racks.

Timer relays to stabilize sequences and reduce nuisance trips

Sequence starts, delays, and watchdog functions with timer relays. Typical functions include on-delay, off-delay, interval, star-delta, cyclic, and one-shot. Parameterize ranges that match your process windows and document settings in the panel pack.
Engineering focus: timing accuracy over temperature, supply tolerance, relay life under expected duty, and front-panel readability for maintenance.

Coordination for motor circuits with Unitec devices

• Select overloads by motor FLA and duty; confirm trip class to match thermal profile.
• Check short-circuit withstand and verify type 1 vs type 2 coordination with upstream protection.
• Validate auxiliary feedback to PLC for starters and safety interlocks.

Panel documentation and QA checklist

1. Single control-voltage policy (e.g., 24 V DC) to cut SKUs and training.
2. Terminal coding and wire ferrules aligned with drawings and device labels.
3. Torque logs for terminals; routine verification records and dielectric tests.
4. Selectivity tables and heat-rise assumptions filed with the project pack.
5. Spares list by board: coils, contact blocks, sockets, and timing modules.

Commissioning and maintenance practices

• Record pickup/dropout for critical coils and verify chatter-free PLC inputs.
• Use secondary injection or function tests to confirm protection behaviour.
• Schedule quarterly inspections for hot spots, loose terminals, and relay cycle counts.
• Keep a quarantine bin for removed protective devices to prevent accidental reuse.
