Motorola FLN3524A | ACE3600 CPU3640 Controller Module

The Motorola FLN3524A is a high-performance central processing unit (CPU) module designed specifically for the ACE3600 Remote Terminal Unit (RTU) family.

As the "brain" of the ACE3600 system, the FLN3524A (often labeled as the CPU3640) manages complex logic, data logging,

and multi-protocol communications in mission-critical SCADA and industrial automation environments.

Technical Parameter Table

High-Security Standards: Features advanced encryption and security protocols designed to protect critical infrastructure from cyber threats.

Large Scale I/O Support: Capable of managing up to 110 I/O modules via expansion, making it suitable for both small local sites and large-scale plant automation.

Protocol Versatility: Supports simultaneous communication over multiple media (radio, cellular, landline, and Ethernet) using MDLC, Modbus, and DNP3.

Redundancy Capability: Can be configured in a redundant CPU mode for zero-fail operations in power or water utility applications.

Ruggedized for Field Use: Specifically built to withstand the electrical noise and temperature fluctuations found in outdoor NEMA enclosures.

Application Cases

Water & Wastewater: Monitoring pump stations, tank levels, and water quality sensors across a wide geographic area.

Oil & Gas: Real-time data acquisition and valve control for pipeline monitoring and wellhead automation.

Electric Utilities: Substation automation and smart grid management where high-speed protection logic is required.

Public Safety: Managing siren warning systems and remote telemetry for emergency responder infrastructure.

Other Models in the Same Series

The ACE3600/Moscad ecosystem includes several compatible power and I/O modules:

FLN3527A: Mixed I/O module (Analog and Digital).

FPN1640A: 18-72 VDC Power Supply module often paired with the FLN3524A.

FLN3641A: Alternative CPU module version with different memory/port configurations.

ACE3680: A compact variant of the RTU family for smaller-scale deployments.

Installation and Maintenance

Installation: Insert the FLN3524A into the designated CPU slot (usually the first or second slot) of the ACE3600 frame. Ensure the module is firmly seated and the front panel screws are secured to the frame ground.

Battery Maintenance: The module typically contains a backup battery for non-volatile RAM. It is recommended to replace this battery every 2–3 years to prevent configuration loss during power cycles.

Firmware Updates: Use the Motorola STS (System Tool Suite) software to upload application logic and update firmware via the Ethernet or Serial programming port.

Cleaning: Ensure the ventilation slots on the RTU housing are clear of dust. Use low-pressure compressed air for cleaning internal components during scheduled maintenance.

Unique Product Description

The Motorola FLN3524A is the definitive choice for engineers who require a "fortress" for their data. Unlike standard PLCs,

the ACE3600 CPU3640 is built with a deep emphasis on secure communication over radio and long-distance networks.

It excels in "invisible" infrastructure—the remote sites where reliability isn't just a metric, but a requirement for public safety.

By combining the power of a RISC processor with the versatility of the MDLC protocol, this module ensures your remote assets stay connected, secure, and fully operational.
