ProComSol HM-USB-PWR USB HART Modem with Power

USB HART modem that also powers the HART transmitter — +24 Vdc from USB or AC outlet, 1500 Vdc opto-isolation, built-in loop resistor, and mini-grabber clips for Windows or Android configuration work.

Key advantages

Modem + power — configure HART transmitters without a separate loop supply.
+24 Vdc supply — from USB connection or AC outlet; self-powered modem (no batteries).
1500 Vdc isolation — opto isolation between HART and USB circuits; HCF_SPEC-54 physical layer design.
Host flexibility — Windows 7–11 (32/64-bit) virtual COM port; Android via DevComDroid; works with DevCom2000 and many HART apps.

Typical applications

Bench or field setup of HART transmitters with PC/tablet software.
Commissioning loops where a portable 24 V supply is otherwise missing.
Maintenance laptops needing a rugged ABS HART modem with grabbers.

Selection guide

Model — HM-USB-PWR (USB HART modem with integrated power supply).
Connectors — Integral USB Type A; heavy-duty HART mini-grabbers.
Loop resistor — Built-in.
Software — Virtual serial port driver + modem test program; DevCom2000 / DevComDroid (confirm package on RFQ).
Warranty — 1 year (OEM).

Common mistakes

Ordering a modem-only unit when integrated 24 V power is the reason for HM-USB-PWR.
Assuming phone/tablet USB-C hosts without checking OTG/power capability.
Forgetting HART software licensing (DevCom) if not already owned.
Calibration

When to RFQ / what to tell us

Confirm HM-USB-PWR (powered) vs modem-only siblings.
Windows vs Android; DevCom software needs.
Quantity; ship-to.

FAQ

Q: Does USB alone power the transmitter? A: OEM states +24 Vdc supply from USB connection or AC outlet — confirm host USB power budget for your transmitter; use AC when needed.

Q: What should I send for a quote? A: Quantity, host OS, software needs. Compatible with systems using ProComSol HM-USB-PWR if you need a drop-in check — we do not claim authorized-dealer status.
