Product Overview

Endress+Hauser AG319100-0200C/D Ruggedized PCB Module: Industrial Resilience for Harsh Environments

The Endress+Hauser AG319100-0200C and AG319100-0200D are precision-engineered PCB replacement boards designed for continuous, fault-free operation in the most demanding process instrumentation environments. Built to Endress+Hauser’s exacting German engineering standards, these boards serve as the electronic backbone of field transmitters and measurement systems deployed across oil & gas, chemical processing, water treatment, metallurgy, and power generation facilities worldwide.

Whether your plant operates under extreme thermal cycling, persistent vibration, corrosive atmospheres, or high electromagnetic interference (EMI), the AG319100-0200C/D delivers the signal integrity and processing stability that mission-critical instrumentation demands. Its robust PCB construction — featuring conformal coating, reinforced solder joints, and industrial-grade component selection — ensures reliable performance across the full operating temperature range without derating.

In continuous production lines where unplanned downtime translates directly to lost revenue and safety risk, having a verified, tested replacement board in stock is not optional — it is a core element of your maintenance strategy. The AG319100-0200C/D is a direct form-fit-function replacement for the original Endress+Hauser board assembly, eliminating the need for recalibration or firmware re-flashing in most field applications.

Comprehensive Protection Solutions

The AG319100-0200C/D does not operate in isolation — it is a critical node within a broader instrumentation and control architecture. In a typical process plant, this board interfaces directly with the transmitter’s 4–20 mA HART output loop, feeding real-time process values to a Siemens S7-300 or S7-400 PLC via analog input modules such as the SM 331. In DCS environments, it integrates seamlessly with Emerson DeltaV I/O cards and Honeywell Experion C300 controller modules, maintaining signal fidelity even under high-density cable routing conditions.

For installations where the transmitter is mounted in a hazardous area (Zone 1 or Zone 2), the AG319100-0200C/D is paired with Endress+Hauser RN221N or RN221 Zener barriers and galvanic isolators to maintain intrinsic safety compliance. In control cabinet assemblies, it works alongside Phoenix Contact QUINT power supplies and Weidmüller WDU terminal blocks, ensuring clean, stable power delivery and reliable field wiring termination.

When deployed in high-vibration environments such as compressor skids or rotating machinery platforms, the board is typically installed within Endress+Hauser TMT82 or TMT84 temperature transmitter housings, which provide additional mechanical damping. In wet or chemically aggressive environments — common in water treatment and chemical dosing systems — the conformal-coated PCB resists moisture ingress and chemical vapor attack far more effectively than standard commercial-grade boards.

For facilities running PROFIBUS PA or FOUNDATION Fieldbus H1 networks, the AG319100-0200C/D supports the communication stack required for digital process variable transmission, alarm signaling, and remote diagnostics — reducing the need for physical site visits during routine maintenance cycles. This capability is particularly valuable in offshore platforms and remote pipeline monitoring stations where technician access is costly and time-constrained.

Application in Critical Infrastructure

Oil & Gas: On upstream wellhead platforms and midstream pipeline compression stations, the AG319100-0200C/D maintains accurate flow and pressure measurement under continuous mechanical vibration, wide ambient temperature swings, and exposure to H₂S-laden atmospheres. Its robust design supports SIL 2 functional safety loops when integrated with certified safety instrumented systems (SIS).

Power Generation: In coal-fired, gas turbine, and nuclear auxiliary systems, this board sustains reliable level and temperature measurement in steam drum and feedwater circuits. Its EMI-hardened design prevents measurement drift caused by high-voltage switching transients from nearby variable frequency drives (VFDs) and large motor starters.

Water & Wastewater Treatment: Municipal and industrial water treatment plants rely on continuous flow and chemical dosing measurement. The AG319100-0200C/D withstands the high-humidity, chlorine-rich atmospheres typical of chlorination and ozonation facilities, maintaining calibration stability over extended service intervals.

Metallurgy & Mining: In blast furnace gas measurement, ore slurry flow monitoring, and smelter off-gas analysis, this board operates reliably under extreme dust loading, thermal shock, and ground loop interference — conditions that rapidly degrade standard instrumentation electronics.

Chemical Processing: Continuous chemical reactors and distillation columns demand uninterrupted process variable feedback. The AG319100-0200C/D supports ATEX and IECEx certified installations in Zone 1 and Zone 2 classified areas, making it suitable for ethylene, ammonia, and chlorine production environments.

Security & Quality FAQ

Q1: What does the 12-month warranty cover?
The 12-month warranty covers all manufacturing defects, component failures, and functional faults under normal operating conditions. If the board fails within the warranty period, TOPNLMS will provide a free replacement or full refund. The warranty period begins from the date of confirmed delivery.

Q2: How is each unit tested before shipment?
Every AG319100-0200C/D unit undergoes a full functional test bench inspection prior to dispatch. This includes power-on verification, signal output validation, and visual inspection for physical damage. A test report is available upon request for quality-critical procurement processes.

Q3: Is this board compatible with my existing Endress+Hauser transmitter?
The AG319100-0200C and AG319100-0200D are direct replacement boards for the Endress+Hauser AG31 series field transmitters. If you are unsure about compatibility with your specific instrument model or firmware version, please contact our technical team with your transmitter nameplate data and we will confirm compatibility before shipment.

Q4: Can TOPNLMS guarantee long-term supply for ongoing maintenance programs?
Yes. TOPNLMS maintains dedicated stock of critical Endress+Hauser spare parts to support planned maintenance, turnaround shutdowns, and emergency replacement requirements. We can provide blanket order arrangements and reserved stock agreements for facilities with high-volume or time-sensitive spare parts programs. Contact us to discuss your site’s specific requirements.
