GE IC800SSI216RD2-CE: Your Go-To Serial Interface for Legacy PLC Systems

If you’re maintaining older GE Fanuc IC800 Series PLCs (and let’s be honest, plenty of plants still run these rock-solid systems), this module solves that nagging serial comms headache. One thing I appreciate is how it quietly handles RS-422/485 chatter between your PLC and field devices—think barcode scanners on packaging lines or motor drives in bottling plants—without needing a full system overhaul. You might notice it’s become a lifeline for facilities avoiding costly migrations, like that Midwest automotive plant that extended their IC800 line’s life by seven years using these.

Key Features That Actually Matter

• Dual-port flexibility – Runs both RS-422 and RS-485 protocols simultaneously. Saved a food processing client from rewiring their entire fill line when they added new sensors last year.
• 2500V galvanic isolation – Blocks electrical noise from welders or VFDs. In pulp mills I’ve seen, this prevents 90% of those mysterious comms dropouts.
• LED diagnostics built in – No more guessing if it’s the cable or the module. That blinking TX/RX pattern? It told a technician exactly where his conveyor comms failed at 2AM.
• Backplane-powered – Draws only 150mA from the IC800 rack. No separate PSU needed, which simplifies cabinet space in retrofits.

Technical Snapshot

Where You’ll Actually Use This

From my experience, it’s not about greenfield projects—it’s keeping aging but critical systems alive. Cement plants use it to connect kiln temperature controllers to legacy PLCs. Water treatment facilities rely on it for SCADA comms where Ethernet upgrades aren’t budgeted. One paper mill engineer told me: “It’s the last piece keeping our 2003 coater line breathing.” If you’ve got IC800 racks gathering dust in a cabinet, this is your comms lifeline.

Why Procurement Teams Keep Ordering It

Let’s cut through the fluff: it’s cheaper than ripping out whole PLC systems. The 365-day warranty gives peace of mind for critical spares, and since it’s backward-compatible with existing IC800 wiring, you avoid engineering redesign costs. In many cases, the ROI shows up when production doesn’t stop because a single comms module failed. Oh, and if your maintenance team already knows IC800 systems? Zero retraining needed.

Installation & Maintenance Reality Check

Mount it in a standard IC800 rack—no surprises there. But here’s what manuals don’t stress: keep it at least 10cm from VFDs or high-power relays. I’ve seen noise issues when plants cram everything together. Ventilation matters too; above 60°C ambient, those comms errors creep back in. For maintenance? Wipe dust off connectors quarterly (those screw terminals collect grime), and check terminal tightness during annual shutdowns. No firmware updates—this thing’s too old for that—but verify cable shields are grounded properly. One client skipped that and fought comms glitches for months.

Ordering & Peace of Mind

We keep genuine stock—no refurbished units. In-stock items ship in 1 week; worst-case scenario is 4 weeks if we need to pull from our global network. Payment’s simple: 50% upfront, balance before we ship via DHL/UPS/FedEx (your choice). And that 365-day warranty? Covers failures from normal operation, not lightning strikes or coolant spills. One plant manager said it best: “Knowing I’ve got a year to catch intermittent issues beats gambling with eBay parts.”
