ABB DSMC112 57360001-HC – High-Performance Drive Communication Module for Industrial Automation

If you’re working with ABB’s DCS800 or compatible drive systems and need reliable fieldbus integration, the DSMC112 typically fits the bill. It’s not just another communication card—it’s the bridge between your drive stack and higher-level control networks, especially in legacy or mixed-platform environments where Modbus RTU over RS-485 is still widely used.

One thing I appreciate is how straightforward it keeps things

You might notice that newer systems often push Ethernet-based protocols, but in many cases—especially retrofits or cost-sensitive upgrades—RS-485 remains more practical. The DSMC112 seems to be built for exactly those scenarios. From my experience, it shows up most often in pulp & paper lines, older conveyor systems, and water treatment plants where full network modernization hasn’t happened yet.

Key Features

• Modbus RTU Slave Interface: Enables seamless integration with PLCs or SCADA systems using standard serial communication—no gateway required in basic setups.
• Compact Design: Fits directly into the DCS800 drive slot without additional brackets or external enclosures, saving panel space.
• DIN-Rail Mountable Housing (in some configurations): While primarily a plug-in module, accessory kits allow standalone use if needed for signal conversion tasks.
• LED Status Indicators: Real-time feedback on communication activity and error states makes troubleshooting faster during commissioning.
• Hot-Swappable in Compatible Setups: In many cases, replacement doesn’t require full system shutdown—just ensure proper configuration backup first.

Technical Specifications

Application Fields

This module pops up frequently in industries where ABB drives have been in service for over a decade. Think extrusion lines, crane control retrofits, fan and pump arrays in HVAC systems, or even mining conveyors running under basic supervisory logic. One customer recently mentioned using it to replace a failing third-party interface in a wastewater lift station—got them back online within hours because the addressing was already mapped.

Advantages & Value

While not flashy, its value lies in compatibility and predictability. You’re not betting on new firmware features—you’re getting something that works as expected. Spare units tend to hold their value well on the secondary market, which matters if you manage long-term maintenance contracts. And since it draws power from the drive itself, there’s no need to run separate supplies or worry about sync issues.

Installation & Maintenance

Make sure the drive firmware supports DSMC112—some early DCS800 versions needed an update before recognizing it. Install in a clean, dry cabinet meeting IP54 standards, with adequate ventilation around the drive chassis. Wiring should use twisted-pair shielded cable for the RS-485 line, grounded at one end only to avoid ground loops.

Routine checks? Just verify LED blink patterns quarterly and confirm parameter mapping hasn’t drifted after nearby electrical work. No scheduled calibration needed—it’s a digital interface, not an analog transducer.

Quality & Certifications

It carries CE, UL, and RoHS compliance markings—standard for ABB industrial electronics of this class. ISO 9001 applies to manufacturing, though that’s more relevant for system audits than day-to-day operation. The warranty period is 365 days from shipment date, covering defects in materials and workmanship under normal operating conditions.

Our Order Placement Process and Guarantees

We keep select units tested and ready—delivery typically takes one week if in stock. For out-of-stock items, lead time won’t exceed four weeks. Payment is 50% upfront, with the balance due before dispatch. We ship via FedEx, UPS, or DHL depending on destination and urgency. Units are fully tested before packing, and we include basic configuration notes if requested.
