Azbil (Yamatake) EST0240Z05WBX00 – Compact DIN-rail Temperature Transmitter for RTD to 4–20 mA

The YAMATAKE-EST0240Z05WBX00 typically belongs to Azbil’s EST series of compact, industrial temperature transmitters. From my experience, this model is used to convert an RTD (commonly Pt100) signal into a stable 4–20 mA loop output for PLCs, DCS, or data loggers. You might notice that it’s designed for tight panels and OEM skids where a low-noise, loop-powered analog signal just makes life easier for controls engineers.

Company’s Order Placement Process and Guarantees

Key Features

• RTD to 4–20 mA conversion – Converts Pt100 RTD input into a stable 2‑wire loop signal for most PLC/DCS analog inputs.
• Compact DIN-rail footprint – Slim housing saves cabinet space; ideal for multi-point temperature panels.
• Noise-resistant, loop-powered design – Typically powered from the current loop (around 24 VDC) to reduce wiring complexity.
• Industrial operating range – Designed to run reliably in control cabinets with ambient heat and continuous duty.
• Consistent accuracy – Provides linearized output for Pt100 input, which helps reduce controller-side scaling issues.
• Simple integration – Standard 4–20 mA output makes it drop-in compatible with most brands of PLC AI cards.

Technical Specifications

Notes: The EST0240Z05WBX00 designation appears to indicate an EST-series transmitter with a 24 VDC loop environment and standard options common to Pt100 inputs. If you need a thermocouple variant or different wiring scheme, we can verify the exact code pairing before shipment.

Application Fields

• HVAC and building automation – Supply/return temperature monitoring, AHU coil protection, and energy metering inputs.
• Process skids – Food & beverage, pharma utility panels, and CIP/SIP loops where clean 4–20 mA signals are preferred.
• Factory automation – Oven, dryer, and heater temperature feedback to PLCs for closed-loop control.
• OEM machinery – Compact panels with multi-point RTD measurements feeding a shared AI module.

Advantages & Value

• Reliable signal chain – Stable, linearized 4–20 mA reduces programming overhead and nuisance alarms.
• Broad compatibility – Works with most PLC/DCS AI cards without special scaling blocks.
• Space and wiring savings – Slim DIN-rail form factor and loop-powered wiring simplify cabinet layouts.
• Total cost control – In many cases, lowers commissioning time compared to raw sensor direct-wiring.
• Support you can reach – We can help cross-check the exact EST code against your RTD type and range before ordering.

Installation & Maintenance

• Panel environment – Mount vertically on TS-35 DIN rail with adequate ventilation; avoid hot spots near drives.
• Wiring – Use twisted, shielded cable for RTD leads; ground the shield at one end only to minimize loops.
• Sensor hookup – For 3‑wire Pt100, match lead resistance; keep sensor wiring separate from power lines.
• Power loop – Ensure 12–36 VDC loop supply with headroom for total loop resistance.
• Routine checks – Periodically verify output at known temperature points; clean terminals and re-torque screws annually.
• Firmware/config – If a configuration tool is used, save parameter backups; update only when necessary and validated.
• Safety – De-energize the loop before service; follow local electrical codes for control panels.

Quality & Certifications

• CE and RoHS compliance typically available for this series
• UL/cUL for control panel components in many cases
• Manufacturer warranty: typically 12 months; we support a 365-day warranty window
