HRT-370 HART Signal Filter, 1-ch Analog Current Output with HART Bypass
DIN-rail HART signal filter that splits a HART loop into a filtered analog current output and a bypass HART channel, keeping analog readings clean when HART traffic is present.
- One analogue current output channel with HART signal filtering, plus one bypass HART signal channel
- Supports HART Burst mode and point-to-point HART mode, with two HART masters allowed
- Loop power function provides +30 V output from the module
- Analogue output zero and span drift of ± 0.1% FSR @25 °C and ± 0.5% FSR @-30/+80 °C
- 2500 VDC isolation on the analogue output and HART side, with 4 KV ESD protection
- Input impedance 250Ω ±5% (2 W) and auxiliary supply 24 V @ 20 mA

Produktinformation "HRT-370 HART Signal Filter, 1-ch Analog Current Output with HART Bypass"
HRT-370 is a HART signal filter for installations where an analogue current reading and HART communication share the same loop. The HART signal is split into two outputs: one passes the original HART signal through, while the other delivers a filtered, pure analogue current, so both data paths can be processed without interference from the HART carrier.
The module works with 2-wired or 4-wired HART devices in point-to-point connections and supports both HART Burst mode and point-to-point HART mode. It allows two HART masters to be connected, and its loop power function supplies +30 V from the module. The analogue output is isolated to 2500 VDC and specified with a 250Ω load resistor and 40 ms response time at 250 Ω.
- Suits engineers who need both HART data and a stable analogue current from one instrument.
- Mounts on DIN-rail, with an unregulated +10 ~ +30 VDC supply input and reverse polarity protection.
- Rated for operation from -25 ~ +75 °C, with storage from -30 ~ +80 °C.
Applications
- Measuring analogue current from HART transmitters while keeping HART communication active on the same loop
- Point-to-point HART instrument loops where analogue data collection must remain precise
