F&F Industrial Automation Spare Parts

The F&F PCR-513 Time Relay is designed for precise time control in both industrial and domestic automation systems, such as ventilation, heating, lighting, and signaling. This relay operates by delaying activation, ensuring reliable and accurate timing functions. Upon applying supply voltage, the contact remains in position 11-10, and the preset time begins to count down. Once the time elapses, the contact switches to position 11-12. The relay's operation can be reset by disconnecting and reconnecting the supply voltage.Key Features:Wide range of time settings from 0.1 seconds to 24 daysMountable on a 35 mm DIN railStable operation with smooth time adjustment within the set rangeON/OFF modes for permanent contact positionsApplications:Ideal for use in various automation systems, including HVAC, lighting control, and signaling, the PCR-513 ensures precise and reliable time-based control, enhancing the efficiency and functionality of your automation processes.

The Phase Sequence and Loss Sensor CKF-317 is designed to safeguard three-phase electric motors from potential damage caused by phase loss or voltage asymmetry. It ensures motor protection by monitoring the voltage in each phase and disconnecting the motor if an anomaly is detected. The sensor features an adjustable voltage asymmetry threshold and a delay of 4 seconds to prevent accidental shutdowns due to temporary voltage drops. Automatic reconnection occurs when the voltage rises 5V above the activation threshold. Additionally, the sensor prevents motor startup if the phase sequence is incorrect, ensuring proper motor rotation direction. The device is equipped with a relay output (1 x NO/NC) and provides clear status indication via two LEDs.Applications: Ideal for use in industrial settings where three-phase motors are employed, ensuring reliable operation and protection against phase-related issues.

The CKF-316 Phase Sequence and Loss Sensor is designed to safeguard three-phase electric motors from potential damage caused by phase loss or voltage asymmetry. This sensor is essential for maintaining the integrity and performance of motors in industrial applications. It automatically disconnects the motor if voltage drops in any phase or if there is a significant voltage imbalance, preventing motor damage. The sensor also ensures the correct rotation direction of the motor by monitoring phase sequence changes, preventing undesired motor operation.In the event of voltage loss or asymmetry exceeding the activation threshold, the sensor will disconnect the motor with a 4-second delay to avoid accidental shutdowns due to temporary voltage drops. The motor will automatically reconnect when the voltage increases by 5V above the activation threshold, ensuring seamless operation. If the phase sequence changes, the sensor will prevent the motor from starting until the correct sequence is restored.The CKF-316 is equipped with a relay actuator, has a maximum load current of 8A, and features a single NO/NC contact configuration. It includes LED indicators for power monitoring and is designed for easy installation on a 35mm DIN rail. With a robust design and reliable performance, the CKF-316 is an ideal solution for protecting motors in various industrial settings.
