PC4012-E

The Okuma PC4012-E control board from the E4809 CNC Boards series delivers robust high-voltage switching capabilities in a compact form factor, engineered for demanding industrial automation environments. It supports a rated operational voltage (Ue) of AC 690V and sustains switching currents up to 12A (ac-3, 400V), providing reliable performance for medium-to-heavy load control. Designed and manufactured by Okuma in compliance with IEC 60947-4-1, the board ensures adherence to stringent safety and performance standards. Its high endurance design encompasses both a mechanical endurance of 10 million operations and an electrical endurance of 1 million operations, guaranteeing long-term reliability in high-cycle applications. With a rated insulation voltage (Ui) of AC 1000V, this board excels in high-voltage control tasks where consistent insulation performance is critical.

All critical specifications are carefully balanced to meet rigorous application demands. The PC4012-E offers IP20 degree of protection, safeguarding internal assemblies against inadvertent contact and solid objects larger than 12.5 mm. Coil drive flexibility is provided by multiple coil voltage options, accommodating diverse control circuit requirements without hardware changes. The contact configuration of 3NO + 1NC permits both normally open and normally closed switching, optimizing circuit design in motor starters and multi-function control schemes. At a rated power of 5.5 kW (ac-3, 400V), the board supports reversing, star-delta, and soft-start applications. Weighing just approx. 350g, the unit minimizes added mass in compact switchgear designs.

Operational performance emphasizes safety and consistency under challenging conditions. Dual mounting options—DIN rail or screw mounting—facilitate rapid installation in control panels or switchgear assemblies, reducing downtime during service. The board’s high endurance rating stems from precision-engineered contacts and durable insulating materials that maintain low contact resistance over millions of cycles. Consistent coil response and low chatter are assured through optimized electromagnetic design and stringent factory calibration. Thermal stability across the operating range preserves contact integrity under fluctuating load conditions, while the protective coating on printed circuit tracks resists moisture and corrosion.

System integration is streamlined for modern CNC and PLC-based automation platforms. The PC4012-E’s standard-compatible form factor ensures drop-in replacement or upgrade paths in existing Okuma systems, minimizing engineering reconfiguration. Its comprehensive compliance with IEC 60947-4-1 enables seamless certification in global installations, while the flexible coil voltage options support cross-regional deployments. Ideal applications include motor control centers, switchgear assemblies, and industrial automation systems where high durability, precise control, and simplified integration are paramount.
