The
ABB DLM01 is a versatile digital input/output (DI/DO) module designed for industrial automation systems, part of the ABB S800 I/O series compatible with the AC800M and AC500 systems. Engineered for reliable signal processing, the
DLM01 offers 8 channels of digital inputs (DI) and 8 channels of digital outputs (DO), combining both functions in a compact form factor (45×102×119 mm). Its dual isolated groups (2×8 channels for DI/DO) with surge protection ensures robust performance in harsh environments. The module supports configurable input filtering (2/4/8/16 ms) and output response times (0.5 ms typical), making it ideal for real-time control applications. With certifications like EN 61010 and ATEX Zone 2, the
DLM01 meets global safety and environmental standards.

- Dual-Function Integration: Combines 8 DI and 8 DO channels in one module, reducing cabinet space and wiring complexity.
- Surge Protection: Built-in transient voltage suppression (TVS) on DO channels (600V surge) and reverse polarity protection for inputs/outputs.
- Diagnostic Capabilities: LED indicators for channel status (DI: 0/1; DO: on/off), fault (F), run (R), and warning (W), plus short-circuit/overload protection on outputs.
- Modular Flexibility: Compatible with ABB’s S800 I/O MTUs (e.g., TU810V1, TU814V1), supporting vertical/horizontal mounting and hot-swap capability.
- Energy Efficiency: Low power consumption (1.5W typical) and sleep mode for reduced standby power.

ABB DLM01
- Industries: Manufacturing (machinery control), energy (substation automation), water/wastewater, food & beverage, and logistics (conveyor systems).
- Use Case:
- Food Processing Plant: Controlling conveyor belt motors (DO) and monitoring proximity sensors (DI) in a bottling line. The DLM01’s surge protection prevented 95% of downtime caused by voltage spikes, improving OEE by 12% over a year.
Compared to single-function or less-integrated modules:
- Higher Integration: 8 DI + 8 DO in one module (vs. separate DI/DO modules), cutting installation costs by 30%.
- Superior Surge Protection: 600V surge rating on DO channels (vs. 400V typical in 竞品), ideal for inductive loads.
- Faster Response: 0.5 ms DO switching (vs. 1–2 ms in similar products), critical for high-speed automation.
- Functionality: Choose the DLM01 for applications needing both DI and DO (e.g., machine control); opt for single-function modules (DI810/DO810) for dedicated inputs/outputs.
- Environment: Verify temperature range (+55°C max certified) and pollution degree (Degree 2) match site conditions.
- Scalability: Pair with ABB’s TU814 MTU for redundant communication in critical systems.
- Budget: Balance integration (reduced wiring) against channel count—cost-effective for mid-density setups (16 I/O total).
-
Wiring: Use shielded cables for DI (max 600m) and stranded wires for DO (16–24 AWG). Follow ABB’s wiring diagrams for proper grounding.
-
Load Management: Ensure DO loads ≤ 0.5A per channel (4A total); use external relays for high-power devices.
-
Installation: Vertical mounting preferred for heat dissipation; avoid exposing to direct sunlight or water.
-
Maintenance: Regularly test DO channels with ABB’s System 800xA diagnostics; replace modules every 10 years (per ABB’s recommended lifecycle).
