Here is an introduction to the HiC2873 Solenoid Driver:

The HiC2873 is a 1 - channel isolated barrier solenoid driver designed by Pepperl+Fuchs for intrinsic safety applications1. It has the following features1:

• Power Supply: It can be powered by either a 20.4 - 30 V DC bus or loop. When powered by a 24 V DC source with a 300 - ohm load, the input current is 62 mA, and the power dissipation is 1 W.

• Control Input: The control input can be an external switch (dry contact or open collector) that is non - isolated, or a fully floating logic signal input. For the logic signal, a 1 - signal is within the range of 15 - 30 V DC (with a current limit of 3 mA) or contact close (with an internal 10 - kΩ pull - up), and a 0 - signal is within the range of 0 - 5 V DC or contact open.

• Output Characteristics: The output provides 40 mA at 12 V DC, with a current limit of 55 mA. The open - loop voltage is approximately 22.5 V, and it can drive a nominal load of 0.1 - 5 kΩ. The switching frequency is up to 150 Hz (filter off) or 15 Hz (filter on) for bus - powered mode, and up to 10 Hz for loop - powered mode. The energized / de - energized delay is 1 ms (filter off) or 10 ms (filter on) for bus - powered mode, and for loop - powered mode, it is 50 ms for switch - on and 6 ms for switch - off (with a 300 - ohm load).

• Line Fault Detection: It can detect short - circuits when the resistance is less than 25 Ω and open - circuits when the resistance is greater than 100 kΩ. The fault indication output is an open - collector transistor (internal fault bus), which emits a 4 - mA pulsing signal (20 ms on, 200 ms off) to indicate faults.

• Galvanic Isolation: There is safe electrical isolation between the output, power supply, and inputs, in accordance with EN 60079 - 11:2007, with a voltage peak value of 375 V.

• 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.

• Safety and Compliance: It achieves a safety integrity level of up to SIL3 (SC3) in accordance with IEC/EN 61508. It complies with electromagnetic compatibility directives such as 2014/30/EU and relevant standards like 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.

In summary, the HiC2873 is a reliable solenoid driver that offers stable power supply and control for solenoids, LEDs, and audible alarms in hazardous areas, ensuring the safety and reliability of industrial automation systems in such environments1.
