ABB 216DB61 HESG324063R100/H – High-Performance Digital I/O Module for Industrial Automation

If you’re working on a compact control system that still demands solid performance, this ABB AC500 series digital input/output module tends to fit the bill pretty well. The 216DB61 (also marked as HESG324063R100/H) is one of those workhorse components that shows up in a lot of OEM panels—especially where reliability and integration with existing ABB PLCs matter. From my experience, it’s typically chosen not because it’s flashy, but because it just works, over and over.

Key Features

• 16-channel digital input: Operates at 24 VDC, with filtering to reduce noise interference—useful in environments with frequent electrical transients.
• Sink/source configurable inputs: Offers flexibility during wiring; one thing I appreciate is how it adapts to different field device types without needing extra relays.
• Integrated diagnostics: LED indicators per channel make troubleshooting faster—on-site techs usually find this cuts downtime significantly.
• Hot-swappable design: In most configurations, you can replace or service the module without powering down the whole rack, which helps maintain uptime.
• Compatible with AC500 PLC ecosystem: Works seamlessly with CPU modules like 260CP500 and backplanes such as HESG324050R, simplifying system expansion.

Technical Specifications

Application Fields

This module pops up frequently in water treatment skids, HVAC control panels, and small-scale packaging lines—basically anywhere an OEM wants deterministic I/O handling without overspending on high-end redundancy. It also seems to be common in retrofits where legacy ABB systems are being expanded incrementally. One customer mentioned using it in a pump station control cabinet where vibration and temperature swings were concerns; after two years, no field failures reported.

Advantages & Value

Procurement teams tend to like this model because it balances cost and compatibility. You’re not locked into proprietary tooling—standard screwdrivers and 0.2–2.5 mm² wires are all you need. Firmware updates are handled through standard PCM software, so there’s no learning curve if your team already uses ABB tools. In many cases, sourcing a replacement locally ends up being harder than just ordering a new one from a reliable supplier, which is where delivery timelines become important.

Installation & Maintenance

Mount it on a clean DIN rail inside an IP54-rated enclosure, ideally with at least 10 mm clearance on both sides for heat dissipation. Avoid placing near VFDs or transformers unless shielded conduit is used—the inputs are filtered, but EMI can still cause glitches in extreme cases. Routine maintenance is minimal: check terminal tightness annually, clean dust buildup every 18 months, and verify firmware version during major system checks. Calibration isn’t required since it’s a digital-only module, but diagnostic logs should be reviewed periodically if connected to a supervisory system.

Quality & Certifications

It carries CE, UL, and RoHS compliance marks—typically sufficient for most EU and North American installations. The build quality feels robust: polycarbonate housing, gold-plated contacts, and clear labeling that doesn’t fade easily. Comes with a 365-day warranty covering defects in materials and workmanship. No registration needed—just keep the invoice and original packaging in case a claim arises.

Order Placement & Guarantees

• Delivery time: 1 week for in-stock units; no more than one month if shipped from secondary warehouse.
• Payment method: 50% advance payment, full balance due before shipment.
• Express delivery: FedEx, UPS, or DHL—tracking provided within 24 hours of dispatch.
