Product Details

105296 R0001 E5LA Product Description

The ABB 105296 R0001 E5LA is not a standalone component — it is a foundational power layer element engineered to sustain the full operational integrity of the AC800M distributed control platform. In any well-structured industrial control architecture, power stability is the prerequisite for every other system function. This module delivers precisely regulated DC power to the AC800M backplane, ensuring that the PM891, PM865, and PM864 processor modules receive clean, uninterrupted supply voltage under all load conditions, including cold-start sequencing, hot-standby switchover, and peak I/O scan cycles.

Within the I/O layer, the 105296 R0001 E5LA supports stable operation of S800 I/O modules — including AI810 analog input, AO810 analog output, DI810 digital input, and DO810 digital output modules — by maintaining rail voltage within tolerance even during simultaneous multi-channel switching events. This is critical in process industries where signal integrity directly affects loop control accuracy and alarm response latency.

At the communication layer, the power supply underpins the CI854 PROFIBUS DP communication interface and CI801 Foundation Fieldbus linking module, both of which are sensitive to voltage ripple and transient spikes. By providing a clean power foundation, the 105296 R0001 E5LA ensures that fieldbus communication cycles remain deterministic and that gateway modules maintain synchronization with field devices such as HART-enabled transmitters, positioners, and flow computers.

For redundant control architectures — a standard requirement in power generation, oil and gas, and chemical processing — the 105296 R0001 E5LA is designed to operate in parallel with a secondary power supply module, enabling seamless bumpless transfer during primary supply failure. This redundancy capability integrates directly with the AC800M's built-in redundancy management, coordinated through the PM891 redundant processor pair and the TB807 termination board, without requiring external switchover logic or additional relay panels.

In HMI and supervisory layers, the power supply's stable output supports the communication backplane that links the AC800M controller to ABB System 800xA operator workstations, historian servers, and engineering tools. Stable power at the controller level translates directly to consistent OPC DA/UA data publication rates, reducing latency in trend displays and alarm management consoles. Engineers integrating the AC800M with third-party SCADA platforms via Modbus TCP or IEC 61850 will find that power rail stability is a prerequisite for maintaining gateway synchronization.

From a maintenance and lifecycle perspective, the 105296 R0001 E5LA supports hot-swap replacement procedures consistent with ABB's modular maintenance philosophy. Field engineers can replace the power supply module without de-energizing the full control cabinet, provided the redundant supply is active. This capability significantly reduces planned maintenance windows and eliminates unplanned downtime risk during power module servicing. All units supplied by NANKMOS undergo pre-shipment functional testing, including load regulation verification, ripple measurement, and inrush current profiling, before dispatch.

Power Generation & Utilities: In combined-cycle power plants and hydroelectric facilities, the AC800M platform — powered by the 105296 R0001 E5LA — manages turbine governor control, excitation system interfaces, and grid synchronization logic. The power supply's ability to sustain stable rail voltage during generator load transients is essential for maintaining control loop integrity during grid disturbances.

Oil, Gas & Petrochemical: Offshore platforms and onshore refineries deploy AC800M controllers for wellhead control, separator automation, and compressor surge protection. The 105296 R0001 E5LA supports continuous operation in these environments, where power interruptions to the control system can trigger emergency shutdown sequences and costly production losses. Its compatibility with redundant power architectures aligns with SIL 2/3 functional safety requirements common in HAZOP-reviewed installations.

Water & Wastewater Treatment: Municipal water authorities use AC800M-based systems for pump station automation, chemical dosing control, and SCADA integration. The power supply module ensures that remote I/O stations and communication gateways remain operational during utility power fluctuations, supporting uninterrupted treatment process control.

Mining & Metallurgy: In mineral processing plants and smelting operations, the AC800M controls conveyor sequencing, crusher automation, and furnace temperature regulation. The 105296 R0001 E5LA provides the power foundation for high-density I/O configurations typical in these applications, where hundreds of digital and analog signals must be processed simultaneously without power-induced scan time degradation.

Marine & Shipboard Systems: Vessel automation systems using AC800M for propulsion control, ballast management, and cargo handling require power supply modules certified for marine electrical environments. The 105296 R0001 E5LA's robust design supports operation within the voltage variation ranges typical of shipboard power distribution networks.

Packaging & Discrete Manufacturing: High-speed packaging lines and assembly systems use AC800M for motion coordination, vision system integration, and OEE data collection. The power supply module supports the fast I/O scan rates required for servo drive coordination and reject gate timing, where millisecond-level power stability directly affects product quality outcomes.

Q1: Is the ABB 105296 R0001 E5LA compatible with both simplex and redundant AC800M configurations? Yes. The 105296 R0001 E5LA is designed for use in both simplex and redundant AC800M rack configurations. In redundant deployments, two power supply modules operate in parallel on the same backplane, with automatic load sharing and bumpless failover managed by the AC800M's internal redundancy logic. No external switchover relay or additional wiring is required. NANKMOS supplies matched pairs for redundant installations upon request, with coordinated pre-shipment testing to verify balanced load sharing before dispatch.

Q2: What are the installation and commissioning requirements for integrating this power supply into an existing AC800M control cabinet? The 105296 R0001 E5LA installs directly into the AC800M backplane slot designated for the power supply module. No firmware configuration is required for the power supply itself — it is recognized automatically by the AC800M system upon insertion. Engineers should verify input supply voltage is within the 24 VDC nominal range, confirm grounding continuity per ABB installation guidelines, and perform a post-installation load test using the AC800M diagnostic tools in Control Builder M. NANKMOS provides installation documentation and pre-shipment test reports with each unit to support site commissioning.

Q3: What does the 12-Month Warranty cover, and how does NANKMOS support long-term inventory supply for this module? The 12-Month Warranty covers functional defects in the power supply module under normal operating conditions, including output voltage regulation failure, inrush protection circuit malfunction, and backplane connector integrity issues. Warranty claims are processed with a replacement-first policy to minimize control system downtime. For long-term supply, NANKMOS maintains dedicated inventory of AC800M platform components — including the 105296 R0001 E5LA and related modules such as PM891, CI854, and S800 I/O cards — to support both planned maintenance programs and emergency replacement requirements. Customers with multi-site installations can arrange framework supply agreements for priority allocation and expedited dispatch.
