Here is an English introduction to the HiC2877 Solenoid Driver:

The HiC2877 Solenoid Driver is a 4 - channel isolated barrier solenoid driver developed by Pepperl+Fuchs, designed to meet the demanding requirements of industrial applications, especially in hazardous areas.

Power Supply

• It operates with a loop - powered design, accepting a rated voltage range of 19 - 30 V DC. The power dissipation is relatively low, less than 1 W, which helps to reduce energy consumption and heat generation. When the input voltage is 19 V with a 265 - ohm output load, the current is ≤ 72 mA, and when the input voltage is 30 V, the current is ≤ 50 mA. This stable power supply performance ensures the reliable operation of the solenoid driver under different voltage conditions.




Output Characteristics

• Each channel of the HiC2877 can provide 45 mA at 12 V DC, with an open - loop voltage of ≥ 22.7 V. The internal resistor of each channel is ≤ 238 Ω. These output parameters allow the driver to effectively power a variety of loads, such as solenoids, LEDs, and audible alarms. The energized / de - energized delay for single operation is typically 1.7 ms / 50 µs, and for periodical operation, it is typically 5 µs / 50 µs, enabling precise control over the solenoid's activation and de - activation.




Indicators and Labeling

• The device is equipped with an LED for status indication, which provides visual feedback on the operating state of the solenoid driver. Additionally, there is a labeling space at the front of the device, allowing for easy identification and marking of channels and other relevant information, which is convenient for installation, maintenance, and troubleshooting.




Safety and Compliance

• The HiC2877 achieves a safety integrity level of up to SIL3 according to IEC/EN 61508. It complies with the electromagnetic compatibility directive 2014/30/EU and the relevant standard EN 61326 - 1:2013. It also has EU - type examination certificates and other approvals for use in hazardous areas, with markings such as II (1) G (Ex ia Ga) IIC, II (1) D (Ex ia Da) IIIC, and I (M1) (Ex ia Ma) I. These certifications and approvals ensure that the solenoid driver meets the highest safety and quality standards, making it suitable for use in potentially explosive environments.




Environmental Adaptability

• The driver can operate in an ambient temperature range of - 20 - 60 °C, demonstrating good adaptability to different environmental conditions. The degree of protection is IP20, which provides basic protection against solid objects and dust. Weighing approximately 100 g with dimensions of 12.5 x 106 x 128 mm, it is compact and easy to install in various industrial control cabinets and equipment.




Galvanic Isolation

• There is safe electrical isolation between the input and output of the HiC2877 according to IEC/EN 60079 - 11, with a voltage peak value of 375 V. This galvanic isolation helps to prevent electrical interference and ensure the safety and stability of the entire system, especially in applications where different parts of the circuit need to be electrically separated.

  
  

In conclusion, the HiC2877 Solenoid Driver is a reliable and high - performance device that offers multiple channels, precise control, and excellent safety features, making it an essential component for powering solenoids in industrial automation systems, particularly in hazardous area applications.
