HiC2871 Solenoid Driver
1-channel isolated barrier, 24 V DC supply (loop powered), Output 45 mA at 12 V DC, Up to SIL 3 acc. to IEC/EN 61508, Housing width: 12.5 mm.
Here is an introduction to the HiC2871 Solenoid Driver:
The HiC2871 is a 1 - channel isolated barrier solenoid driver designed by Pepperl+Fuchs for intrinsic safety applications2. Its features are as follows2:
Power Supply: It is loop - powered with a rated voltage range of 19 - 30 V DC. The power dissipation is less than 1 W. When the input voltage is 19 V with a 265 - ohm output load, the current is ≤ 72 mA; when the input voltage is 30 V, the current is ≤ 50 mA.
Output Characteristics: The output provides 45 mA at 12 V DC, and the open - loop voltage is ≥ 22.7 V. The internal resistor is ≤ 238 Ω. 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.
Indicators and Settings: It is equipped with an LED for status display and has a labeling space at the front for easy identification.
Safety and Compliance: It 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.
Environmental Adaptability: The ambient temperature range is - 20 - 60 °C, and the degree of protection is IP20. It weighs approximately 100 g, with dimensions of 12.5 x 106 x 128 mm.
Galvanic Isolation: There is safe electrical isolation between the input and output according to IEC/EN 60079 - 11, with a voltage peak value of 375 V.
In summary, the HiC2871 is a reliable solenoid driver that can supply power to solenoids, LEDs, and audible alarms in hazardous areas, ensuring the safety and stability of industrial automation systems in such environments2. It mounts on a HIC termination board, and the output signal has a resistive characteristic, with the output voltage and current being dependent on the load and the input voltage2.
