Pepperl Fuchs HIC2871 for a Field Load Interface: Understanding the Loop-Powered Supply and Load-Dependent Output Before Procurement
The Pepperl Fuchs HIC2871 is a single-channel solenoid driver used to supply suitable solenoids, indicators or audible alarms through an isolated interface. Its energy comes from the input loop. That feature changes the selection discussion: a nominal input voltage alone does not establish what the complete output circuit will deliver to a particular field load.
| Requested product | Pepperl Fuchs HIC2871 |
|---|---|
| Function | Single-channel isolated solenoid/alarm driver |
| Supply concept | Loop powered; 19–30 V input reference in current datasheet |
| Load reference | Manufacturer describes 12 V at 45 mA at full load |
| Mounting | HiC termination board; board identity must match the installation |
What does loop powered mean here?
With Pepperl Fuchs HIC2871, the output energy is derived from the input signal instead of an independently assumed auxiliary supply. The manufacturer describes a resistive output characteristic, meaning voltage and current depend on load and input conditions. Use the applicable output characteristic and the approved loop calculation for the actual application. The stated full-load reference is not a blanket approval for any coil bearing a similar voltage marking.
Why the coil label matters
For Pepperl Fuchs HIC2871, identify the actual field load rather than using the word solenoid as a complete specification. Record its electrical requirements and the approved loop design. A valve assembly can contain a coil with options that are not obvious from the mechanical valve number. The Pepperl Fuchs HIC2871 comparison should therefore include the coil identification and the control-side signal source.

Keep board and module identities together
A Pepperl Fuchs HIC2871 module is fitted to a HiC termination board. Capture that board designation and the occupied position when preparing a spare request. These details establish the physical and electrical context without implying that the board is part of the module shipment. If Pepperl Fuchs HIC2871 is being purchased for several cabinets, list the intended supported installations so the stores record remains useful beyond the first repair.
The alarm-device case
A request for Pepperl Fuchs HIC2871 may concern an indicator or audible alarm instead of a valve. State that use explicitly. Include the field-device reference and its required behavior when the command changes or power is removed. This directs the engineering review toward the actual controlled function and prevents a valve-focused assumption from entering the purchase specification.
Before accepting a replacement proposal
Ask whether the offered Pepperl Fuchs HIC2871 is the exact marked module or a proposed alternative. A different driver needs a documented application comparison, including its output characteristic and board arrangement. Preserve the original loop references in the purchase file. Qualified personnel should perform the site-required functional checks before returning the connected equipment to service.
Ordering information
Provide Pepperl Fuchs HIC2871, quantity, intended board and load identification. Request the actual item condition and included accessories. Compare the received Pepperl Fuchs HIC2871 marking and connector condition with the agreed offer, then assign the spare to its cabinet or supported equipment group.
