Product Details

CL6824X1-A2 12P0767X012 Product Description

The Fisher CL6824X1-A2 (full SKU: CL6824X1-A2 12P0767X012) is a high-integrity analog input card engineered for the Emerson DeltaV distributed control system (DCS) platform. Designed to serve as a critical data acquisition node in smart factory environments, this module bridges field-level instrumentation — including 4–20 mA transmitters, HART-enabled sensors, and process analyzers — with the upper layers of the automation hierarchy: PLC controllers, SCADA servers, HMI workstations, and enterprise MES/ERP systems. Its role in the industrial data chain is foundational: without reliable, protocol-compliant analog input, the entire data flow from sensor to dashboard is compromised.

In modern process automation sites — petrochemical plants, power generation facilities, pharmaceutical production lines, and discrete manufacturing cells — the CL6824X1-A2 functions as the first link in a continuous data chain. Field instruments such as pressure transmitters, flow meters, temperature sensors, and level gauges deliver 4–20 mA signals that are captured, digitized, and transmitted upstream via the DeltaV FOUNDATION Fieldbus or HART communication layer. This digitized process data then flows through the DeltaV controller network to SCADA platforms such as Emerson DeltaV Operate, OSIsoft PI, or Wonderware InTouch, enabling real-time monitoring, alarm management, and historical trending across the entire production site.

The CL6824X1-A2 sits at the intersection of physical process measurement and digital control intelligence. In a typical DeltaV-based smart factory architecture, field instruments — including Emerson Rosemount 3051 pressure transmitters, Micro Motion Coriolis flow meters, and Rosemount 644 temperature transmitters — deliver analog signals directly to the CL6824X1-A2 input channels. The module digitizes these signals and passes them through the DeltaV I/O bus to the DeltaV MD or MQ controller, where control logic executes in real time.

From the DeltaV controller, process data propagates across the plant network via OPC-DA or OPC-UA gateways, feeding SCADA historian servers and HMI displays simultaneously. Operators at DeltaV Operate workstations receive live process values, alarm states, and trend data with sub-second latency. In parallel, HART diagnostic data embedded within the 4–20 mA signal — device status, loop integrity, sensor calibration offsets — is extracted by the CL6824X1-A2 and made available to asset management tools such as Emerson AMS Device Manager, enabling predictive maintenance without interrupting the primary control loop.

For sites integrating variable frequency drives (VFDs) and motor control centers, the analog input data from the CL6824X1-A2 can be cross-referenced with drive feedback signals from Emerson Control Techniques or Nidec drives, enabling coordinated process optimization across pumping, compressor, and conveyor systems. Edge gateway devices — such as the Emerson ROC800 remote operations controller or third-party IIoT gateways — can aggregate CL6824X1-A2 data streams alongside data from Modbus RTU field devices, PROFIBUS DP remote I/O stations, and EtherNet/IP-connected sensors, creating a unified data fabric that feeds cloud analytics platforms and digital twin environments.

In multi-loop control architectures, the CL6824X1-A2 works in concert with DeltaV analog output cards (such as the CL6824X1-A1 series), discrete I/O modules, and DeltaV SIS safety instrumented system components to deliver a fully integrated, redundancy-capable control infrastructure. This modular I/O architecture allows engineers to scale the system incrementally — adding input channels as new measurement points are commissioned — without disrupting existing control loops or requiring controller downtime.

Many industrial sites operate with fragmented instrumentation architectures: legacy 4–20 mA loops that lack digital communication capability, proprietary DCS platforms that cannot natively exchange data with modern SCADA or MES systems, and remote field stations that are invisible to central control rooms. The CL6824X1-A2 directly addresses these challenges within the DeltaV ecosystem.

Protocol Fragmentation: By supporting HART communication over standard 4–20 mA wiring, the CL6824X1-A2 eliminates the need for separate HART multiplexers or protocol converters in most DeltaV installations. Field devices that previously delivered only a raw analog value can now transmit rich diagnostic and configuration data to the DCS, closing the protocol gap between legacy instrumentation and modern digital control systems.

Data Silos and Production Transparency: In plants where process data is trapped in isolated control loops, the CL6824X1-A2 — integrated with DeltaV's OPC-UA server — enables seamless data sharing with MES platforms, quality management systems, and enterprise dashboards. Production managers gain real-time visibility into process KPIs, batch yields, and equipment health metrics that were previously inaccessible outside the DCS operator station.

Remote Monitoring and Alarm Tracking: HART diagnostic data surfaced by the CL6824X1-A2 enables remote identification of sensor drift, loop failures, and device faults before they escalate into process upsets. Alarm rationalization workflows in DeltaV can be configured to trigger maintenance work orders automatically when HART device status changes, reducing unplanned downtime and improving alarm management compliance with ISA-18.2 standards.

System Expansion Without Disruption: The modular DeltaV I/O architecture supported by the CL6824X1-A2 allows new measurement points to be added to an existing DCS without controller replacement or network reconfiguration. This scalability is critical for plants undergoing capacity expansion, process optimization projects, or digital transformation initiatives that require incremental instrumentation upgrades.

Q1: What communication protocols does the Fisher CL6824X1-A2 support? The CL6824X1-A2 supports HART (Highway Addressable Remote Transducer) protocol over standard 4–20 mA analog wiring. Within the Emerson DeltaV platform, HART data is natively processed by the DeltaV controller and made available to SCADA, HMI, and asset management applications via OPC-DA and OPC-UA interfaces. No additional protocol converter is required for DeltaV-native deployments.

Q2: Is the CL6824X1-A2 compatible with both DeltaV S-Series and M-Series controllers? Yes. The CL6824X1-A2 is designed for the Emerson DeltaV I/O subsystem and is compatible with DeltaV S-Series and M-Series controller platforms. It integrates directly into the DeltaV I/O bus without requiring additional interface hardware, supporting both simplex and redundant I/O configurations depending on the controller and carrier assembly used.

Q3: How does the CL6824X1-A2 support remote diagnostics and predictive maintenance? The module passes HART device diagnostic data — including sensor status, loop integrity indicators, and device configuration parameters — from field instruments to the DeltaV controller and onward to Emerson AMS Device Manager. This enables remote condition monitoring of connected field devices without requiring physical access to the instrument or interruption of the control loop, supporting predictive maintenance programs and reducing unplanned shutdowns.
