Description
The 3250-L532M is a specialized Remote Terminal Unit (RTU) built upon the reliable SLC 5/03 processor architecture. Designed for decentralized control, this module enables efficient data acquisition and local logic execution in demanding industrial environments, including electrical substations, oil and gas infrastructure, and large-scale mining operations. By maintaining high-speed serial connectivity and local processing capabilities, it ensures operational continuity at the network edge, effectively isolating field-level faults from the central control system.
Features
-
Integrated Communication: Features native Modbus Slave protocol support on Channel 0, allowing for direct integration into existing SCADA frameworks without the need for external protocol converters.
-
Flexible Serial Connectivity: Equipped with three RJ45 ports: one dedicated RS-232 configuration port and two application-specific ports (PRT1 and PRT2) that support RS-232, RS-422, and RS-485 physical layers.
-
Robust Processing: Leverages the standard SLC 5/03 instruction set to execute complex discrete logic and mathematical functions, providing deterministic performance for critical monitoring tasks.
-
Simplified Deployment: Designed for seamless integration into standard SLC 500 backplanes, utilizing the existing power and communication infrastructure.

Installation Guidelines
- Ensure the system power is disconnected before installing or removing the module from the SLC 500 chassis.
- Use shielded communication cables for all serial connections to minimize EMI interference, especially in high-voltage environments.
- Verify that the RJ45 port selection (RS-232/422/485) matches the specific field device requirements before finalizing wiring.
- Maintain proper ventilation in the control cabinet to ensure the ambient temperature remains within the 0 to 60 deg C operating range.
- Follow standard ESD precautions when handling the module to prevent damage to internal circuitry.
