The SST SST-5136-DNP-PCI is a high-reliability DNP3 (Distributed Network Protocol) communication interface card developed by Schweitzer Engineering Laboratories (SEL) for utility and industrial SCADA systems. Designed as a PCI-bus solution, this module enables legacy control systems to communicate with intelligent electronic devices (IEDs) such as protective relays, RTUs, and meters using DNP3 Level 3/4 over serial connections. The SST-5136-DNP-PCI supports both DNP3 Master and Outstation roles, providing time-synchronized data acquisition, event reporting, and secure command execution. With dual isolated RS-232/485 ports and surge protection (±15 kV ESD), it ensures robust performance in electrically harsh environments like substations or water treatment plants. Its driver compatibility with Windows® and Linux® systems simplifies integration into existing automation infrastructures.

Main Features and Advantages
Protocol precision: Full support for DNP3 Secure Authentication (v5) prevents unauthorized command execution. Dual-port architecture allows simultaneous master/outstation operation or redundant communication paths. Time-stamped event reporting (<1>
Robust connectivity: Automatic baud-rate detection and software-configurable RS-232/485 modes eliminate hardware jumpers. Galvanic isolation protects host systems from ground loops in substation environments. Built-in data loggers buffer 50,000+ events during communication outages.
Engineering efficiency: Precompiled drivers and SEL’s AcSELerator QuickSet software enable configuration in under 15 minutes. Legacy system compatibility avoids costly control hardware upgrades.
Application Field
The SST SST-5136-DNP-PCI bridges critical infrastructure:
Electric Utilities: SCADA integration for substation relays (SEL-351, SEL-421) and feeder monitoring.
Water/Wastewater: Controls pump station RTUs and reservoir level sensors.
Renewables: Interfaces wind farm controllers with plant DCS.
Oil & Gas: Monitors pipeline cathodic protection rectifiers.
In transportation, it tunnels traffic signal data through legacy control centers.
