Product Details

01984-2518-0002 Product Description

The Emerson 01984-2518-0002 is a precision-engineered Analog I/O Module designed for seamless integration within the Fisher DeltaV and broader Emerson DCS control architecture. Purpose-built for process-critical environments, this module delivers reliable analog signal acquisition and output across multi-loop control strategies, supporting 4–20 mA HART-enabled field instruments with deterministic scan rates and high channel density. Its role within the control hierarchy spans the I/O layer, bridging field instrumentation to the controller layer with minimal latency and maximum signal fidelity — a foundational requirement for any scalable, redundancy-capable automation platform.

Engineered to operate within Emerson's modular I/O subsystem, the 01984-2518-0002 supports hot-swap capability and is compatible with standard DeltaV S-series and M-series controller backplanes, enabling non-disruptive maintenance cycles and reducing unplanned downtime in continuous process operations. Its compact form factor and DIN-rail or rack-mount compatibility make it suitable for both greenfield installations and brownfield retrofits across a wide range of industrial sectors.

The 01984-2518-0002 does not operate in isolation — its true value is realized when deployed as part of a coherent, layered automation architecture. In a typical DeltaV-based control system, this analog I/O module interfaces directly with the DeltaV MD Plus Controller or DeltaV M5 Plus Controller via the S-series backplane, enabling deterministic loop execution at the controller layer. The controller communicates upstream to the DeltaV Application Station running DeltaV Operate HMI software, providing operators with real-time process visualization and alarm management.

At the field device layer, the 01984-2518-0002 connects to Fisher FIELDVUE DVC6200 digital valve controllers and Rosemount 3051 pressure transmitters via HART communication, enabling remote diagnostics and predictive maintenance without interrupting process control. For applications requiring redundancy, the module can be paired with a DeltaV redundant I/O carrier and a secondary 01984-2518-0002 module in a 1:1 redundant configuration, ensuring continuous signal availability during single-point failures.

Power distribution to the I/O subsystem is managed through the DeltaV Power Supply PS2 or PS6 units, which provide regulated 24 VDC to the backplane with built-in diagnostics. For installations requiring network-level integration, the DeltaV CHARM I/O Card (CIOC) or DeltaV Remote I/O (RIO) node can extend the I/O subsystem to remote marshalling cabinets, reducing field wiring costs in large-scale process plants.

In safety-instrumented system (SIS) architectures, the 01984-2518-0002 is typically deployed in the basic process control system (BPCS) layer, operating in parallel with DeltaV SIS Logic Solvers that handle safety-critical shutdown functions. This separation of BPCS and SIS layers, while maintaining shared engineering tools through AMS Device Manager, ensures both operational efficiency and functional safety compliance in accordance with IEC 61511.

For communication gateway requirements, the DeltaV OPC-UA Server or Emerson Smart Wireless Gateway WirelessHART can be integrated to extend data visibility to SCADA platforms, MES systems, and cloud-based analytics environments, completing the vertical integration from field device to enterprise layer.

Oil & Gas and Petrochemical Processing: In upstream and downstream hydrocarbon processing facilities, the 01984-2518-0002 is deployed in continuous process control loops managing pressure, flow, temperature, and level variables. Its HART communication capability enables online calibration and valve diagnostics without process interruption, a critical requirement in facilities operating under API 670 and ISA-5.1 standards. Refinery units, gas compression stations, and LNG terminal control systems benefit from the module's high signal accuracy and channel isolation, which prevent cross-loop interference in dense I/O marshalling environments.

Power Generation and Utilities: In combined-cycle power plants and cogeneration facilities, the module supports boiler control, turbine governor feedback, and heat recovery steam generator (HRSG) loop management. Its compatibility with the DeltaV controller platform allows seamless integration with existing plant DCS infrastructure, reducing engineering hours during capacity expansion or control system modernization projects. The 12-Month Warranty coverage provides plant operators with a defined maintenance planning horizon, supporting long-term asset management strategies.

Water and Wastewater Treatment: Municipal and industrial water treatment facilities utilize the 01984-2518-0002 for dosing control, filtration pressure monitoring, and effluent flow management. The module's galvanic channel isolation is particularly valuable in electrochemical process environments where ground loops and common-mode noise can compromise signal integrity. Its compatibility with Emerson's AMS Suite enables predictive maintenance scheduling, reducing reactive maintenance costs in 24/7 operational facilities.

Pharmaceutical and Food & Beverage Manufacturing: In GMP-regulated manufacturing environments, the module supports precise temperature and pressure control in bioreactors, CIP/SIP systems, and filling lines. Its deterministic scan rate and high-resolution analog conversion ensure batch-to-batch consistency, a regulatory requirement under FDA 21 CFR Part 11 and EU GMP Annex 11 frameworks. The module's rack-mount form factor facilitates clean-room panel integration with minimal footprint.

Mining and Metals Processing: In mineral processing plants and smelting operations, the 01984-2518-0002 manages analog signals from conveyor load cells, flotation cell level sensors, and furnace temperature transmitters. Its wide operating temperature range and robust electrical isolation support reliable operation in electrically noisy environments typical of high-power motor drive installations and arc furnace operations.

Q1: Is the Emerson 01984-2518-0002 compatible with both DeltaV S-Series and M-Series controller backplanes, and can it be used in a redundant I/O configuration?

A: Yes. The 01984-2518-0002 is designed for the DeltaV I/O subsystem and is compatible with S-Series and M-Series controller racks. For redundant I/O configurations, the module is paired with a redundant I/O carrier card and a second 01984-2518-0002 module. The DeltaV controller automatically manages switchover between primary and secondary I/O modules in the event of a module fault, with no process interruption. Redundancy configuration is performed through DeltaV Explorer and requires no additional hardware beyond the carrier and secondary module.

Q2: What HART communication capabilities does this module support, and how does it integrate with AMS Device Manager for predictive maintenance?

A: The 01984-2518-0002 supports HART pass-through communication on all analog channels, enabling simultaneous 4–20 mA process variable transmission and HART digital communication for device diagnostics, calibration, and configuration. When integrated with Emerson AMS Device Manager, the module provides a communication path for online device health monitoring, alert management, and calibration scheduling without requiring field technician access to the instrument. This capability supports predictive maintenance programs and reduces mean time to repair (MTTR) in process-critical applications.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time and availability for the 01984-2518-0002?
