8101-HI-TX-02 High?Isolation Two?Channel Signal Transmitter for DIN?Rail I/O

The 8101-HI-TX-02 is a compact, DIN?rail transmitter designed to isolate and convert analog process signals with dependable accuracy. It’s typically used to break ground loops, protect PLC/DAQ inputs, and standardize field signals (for example, 4–20 mA to 4–20 mA or voltage-to-current). From my experience, it fits well in tight control panels where stability and electrical noise immunity matter more than bells and whistles.

• High isolation between input, output, and power – Helps prevent ground loops and protects upstream PLC/remote I/O from surges and common?mode noise.

• Dual?channel architecture (TX?02) – Two independent channels to maximize I/O density on a single DIN segment.

• Flexible signal handling – Commonly supports 4–20 mA, 0–10 V, and similar analog ranges; in many cases configurable per channel.

• 24 VDC cabinet power – Standardized supply for most machine and process panels, simplifying spares and power distribution.

• DIN?rail, slim housing – Saves panel real estate; wiring via screw or spring terminals for quick maintenance.

• Stable thermal performance – Typically specified for extended ambient ranges found in plant rooms and outdoor cabinets.

• Noise?resistant design – You might notice cleaner readings in electrically “busy” cabinets compared to basic isolators.

This model makes sense in process plants and OEM skids where you need clean, repeatable analog signals. Typical examples include:

• Water/Wastewater: isolating level transmitter loops before SCADA RTUs to avoid ground potential issues on long runs.

• Oil & Gas skids: conditioning 0–10 V sensor outputs to 4–20 mA for DCS compatibility.

• Power & Utilities: filtering noisy analog signals inside substation cabinets.

• Food & Beverage: dual channel isolation for temperature or pressure transmitters feeding PLC analog cards.

• HVAC/Building Automation: converting mixed sensor types to a unified 4–20 mA standard.

A maintenance supervisor at a beverage plant told me their analog trends “finally flattened out” after inserting HI?TX modules between field transmitters and a sensitive PLC card—seems to be consistent with what we see in cabinets with variable?speed drives nearby.

• Reliability – High?isolation architecture in many cases outlasts lower?cost isolators in electrically noisy environments.

• Compatibility – Works with standard 24 VDC panels and mainstream PLC/RTU analog cards; straightforward loop integration.

• Space efficiency – Two channels per body can cut rail usage and wiring time versus single?channel blocks.

• Lifecycle cost – Fewer nuisance trips and cleaner measurements typically reduce troubleshooting time and callouts.

• Supportability – Simple I/O mapping, no complex firmware, and easy spare stocking.

• Panel environment – Install on EN 60715 DIN rail inside an IP54 (or better) cabinet. Provide basic ventilation; avoid direct radiant heat.

• Power & wiring – Use a stable 24 VDC source with proper grounding. Keep analog wiring away from VFD outputs; use shielded twisted pairs and land shields at a single point.

• Loop checks – Verify 4 mA and 20 mA endpoints after commissioning. You might notice improved linearity once isolation is in place.

• Maintenance – Minimal. Periodic terminal re?torque, dust removal with dry air, and annual loop validation are usually sufficient.

• Safety – De?energize loops before service. If you need intrinsic safety (Ex ia) or SIL certification, confirm the exact 8101?HI?TX?02 variant—base transmitters are not always IS/SIL.

• CE conformity and RoHS alignment are typical for this class of DIN transmitters.

• UL/cUL listings may apply depending on production lot; we can verify on the nameplate or data sheet before order.

• Standard manufacturer warranty is commonly 12 months; extended coverage can be arranged in many cases.

• 24 VDC DIN?rail PSU (60–120 W) with surge protection for clean analog power.

• DIN end?stops and labeled terminal markers to keep channel wiring organized.

• Shielded twisted?pair cable for low?noise analog runs; ferrules for vibration?resistant terminations.
