The ABB 1MRK001608-CAR02 is a ruggedized protocol conversion gateway engineered to bridge RS-232 and RS-485 serial networks with LONWORKS control systems. Designed for mission-critical industrial environments, this module eliminates protocol barriers between legacy field devices and modern networked automation platforms, enabling cost-effective system modernization without equipment replacement.
Ideal for system integrators, plant engineers, and automation professionals managing hybrid control architectures in process industries, utilities, and building automation. This gateway solves the challenge of integrating serial-based instrumentation into LONWORKS ecosystems while maintaining data integrity and real-time performance.
Key differentiators include 2500V galvanic isolation for electrical noise immunity, extended temperature operation (-40°C to +70°C) for harsh environments, and LONMARK certification ensuring vendor-neutral interoperability. Configurable baud rates up to 115.2 kbps support high-speed data acquisition, while compact DIN-rail mounting (74×370×361mm) optimizes cabinet space utilization.
→ Universal Serial Connectivity
Supports RS-232 point-to-point and RS-485 multi-drop (2-wire/4-wire) configurations with auto-detection of communication parameters. Eliminates manual configuration errors and reduces commissioning time by 60% compared to traditional gateways.
→ LONWORKS Network Integration
Full ISO/IEC 14908 compliance with LONMARK certification enables plug-and-play connectivity to certified sensors, actuators, and controllers. Reduces integration risk and ensures long-term system compatibility across multi-vendor installations.
→ Industrial Hardening
Operates reliably in -40°C to +70°C ambient temperatures with 5-95% humidity tolerance. Conformal coating options and IP20 enclosure rating protect electronics from dust, moisture, and chemical exposure in demanding plant environments.
→ Electrical Isolation Protection
2500V AC isolation between serial ports and system ground prevents ground loop damage and protects sensitive control equipment from voltage transients. Reduces equipment failure rates by up to 80% in electrically noisy installations.
✓ Diagnostic Intelligence
Real-time LED status indicators and diagnostic registers provide instant visibility into communication health, error rates, and network activity. Enables proactive maintenance and cuts troubleshooting time from hours to minutes.
✓ Flexible Power Supply
24V DC nominal operation with wide 18-32V DC input range accommodates voltage fluctuations in industrial power systems. Low 8W power consumption supports battery-backed UPS installations for critical applications.

Solution: Gateway modules enable real-time data exchange between legacy equipment and modern analytics platforms. Achieved 22% energy reduction through integrated demand response and predictive scheduling.
Challenge: Interface batch reactor temperature controllers and pressure transmitters (serial protocols) with DCS for 21 CFR Part 11 compliant data logging and process validation.
Solution: High isolation voltage protects process control integrity while enabling bi-directional communication. Reduced validation documentation by 50% through standardized LONWORKS data models.
Challenge: Aggregate data from protective relays, RTUs, and metering devices (DNP3, IEC 60870-5) into utility SCADA via LONWORKS backbone network.
Solution: Extended temperature rating and EMI immunity ensure reliable operation in outdoor switchgear enclosures. Improved fault detection speed by 35% through deterministic LONWORKS messaging.
Challenge: Collect production counts, reject rates, and equipment status from packaging machines (proprietary serial protocols) for MES integration and OEE calculation.
Solution: Configurable serial parameters accommodate diverse equipment vintages. Real-time production visibility enabled 18% throughput improvement through bottleneck identification.

The module supports multi-drop RS-485 networks with up to 32 devices per segment. Use 4-wire RS-485 for full-duplex communication or 2-wire for half-duplex. Terminate both ends of the RS-485 bus with 120Ω resistors to prevent signal reflections. Configure unique device addresses in your serial protocol (e.g., Modbus slave IDs 1-32).
Standard RS-485 supports up to 1200 meters (4000 feet) at lower baud rates (9600 bps). At maximum 115.2 kbps, limit cable runs to 100 meters. Use shielded twisted-pair cable (Belden 9841 or equivalent) and proper grounding to minimize EMI in industrial environments.
Yes. By integrating legacy HVAC and lighting systems into modern LONWORKS-based energy management platforms, facilities typically achieve 15-25% energy savings through optimized scheduling, demand response, and real-time monitoring. ROI typically realized within 18-24 months.
Requires standard 35mm DIN rail (EN 50022) with minimum 400mm clearance for cable routing. Maintain 50mm spacing from adjacent heat-generating equipment. Ensure ambient temperature stays within -40°C to +70°C operating range. Provide adequate ventilation for convection cooling (no forced airflow required).
Yes. Diagnostic data accessible via LONWORKS network variables or optional Ethernet interface (when used with ABB edge gateways). Monitor communication errors, buffer overflows, and port status remotely. SNMP traps and email alerts configurable for critical fault conditions.
Firmware updates performed via LONWORKS network or local RS-232 connection using ABB's configuration tool. Update process takes approximately 5 minutes with automatic rollback on failure. Recommended to update during scheduled maintenance windows to avoid service interruption.
