Functional Role & Application Analysis
The SST 5136-DNP-PCI is a dedicated gateway that bridges your PC-based control software with a DeviceNet field network. It solves the integration challenge of connecting standard Windows PCs to industrial CAN-based devices without requiring a separate PLC. The card’s onboard 40 MHz processor and 256 KB of shared RAM handle the network stack independently. This offloads your host CPU and ensures deterministic communication.
The 500V optical isolation protects your expensive computer hardware from field ground loops and voltage spikes. The card supports all standard DeviceNet data rates and acts as a scanner, adapter, or peer-to-peer node. You can configure multiple cards in a single chassis to segment networks or increase channel count.
Typical deployments include:
- SCADA & HMI Systems: Connecting Windows-based supervisory software to remote I/O, drives, and sensors on the plant floor.
- Machine Control: Serving as the primary network interface for custom PC-based motion or process control applications.
- Data Acquisition: Logging real-time DeviceNet traffic for OEE tracking, predictive maintenance, or quality analysis.
- Legacy System Maintenance: Direct replacement for failed cards in aging control panels where migrating to Ethernet is not feasible.
Our Quality Standard & Testing Process
A failed network card means lost production data and extended troubleshooting. We do not ship untested hardware. Every 5136-DNP-PCI undergoes a rigorous validation process that mirrors actual field conditions. We verify electrical integrity and communication performance before it leaves our facility.
- Visual & Component Inspection: PCBs are inspected for thermal damage, cracked solder joints, and connector pin corrosion. Firmware version is read and documented.
- Live System Test: The card is installed in a PCI test rack and enumerated by the host OS. We verify shared RAM access and interrupt generation.
- Full-Function Diagnostics: We connect a DeviceNet test network and validate communication at 125K, 250K, and 500K baud. Message throughput, error frame handling, and LED status indicators are all verified.
- Warranty Backing: Only units passing all diagnostics are approved for shipment. Every card is backed by our full 12-month warranty.

Compatibility & Migration Paths
Do not assume this card will work in your system without verification. PCI bus timing, driver support, and network configuration are common failure points. You must confirm three critical factors before ordering.
- PCI Bus Compatibility: Verify your motherboard has a standard 5V PCI slot. This card is not compatible with PCIe slots or 3.3V-only backplanes. Check your system manual for slot voltage specifications.
- Driver & OS Support: Confirm your operating system and SCADA/HMI software support the 5136-DNP-PCI. Legacy drivers may be required for Windows XP or older control software. We can provide driver packages.
- Network Termination: The card has no built-in termination resistor. If it sits at the end of a DeviceNet trunk, you must add an external 120Ω resistor between pins 2 and 4. Failure to terminate correctly causes intermittent communication faults.
- Get Expert Help: Send us your motherboard model, OS version, and SCADA software name. We will confirm compatibility and identify any required drivers or accessories before you commit.
