ABB 87TS50-E-E Controller: Keeping Your Process Running When It Counts

If you’ve ever had a controller crash during a critical batch run, you’ll appreciate what this ABB workhorse delivers. The 87TS50-E-E (GKWE857800R1214) isn’t just another PLC—it’s the silent guardian for continuous processes where downtime means six-figure losses. From my time visiting chemical plants, I’ve seen these units handle everything from sudden power dips to corrosive environments without breaking a sweat.

Why plant engineers keep this in their rack

• Dual Ethernet resilience – One thing I appreciate is how it automatically fails over between ports during cable swaps. No more scrambling during network upgrades at 2 AM.
• Hot-swap I/O modules – Replace a faulty analog input card without killing the whole process. Typically saves 3-4 hours per maintenance window in pulp & paper mills.
• Native PROFIBUS/PROFINET – Seems to cut integration time by half versus gateways. A refinery engineer told me it talked straight to their legacy valves on day one.
• Extended temperature tolerance – In many cases, it keeps humming at 60°C where competitors throttle performance. Crucial for those cramped compressor skids.

The specs that actually matter

Where it earns its keep

You’ll find these controllers deep in wastewater treatment plants managing aeration cycles, or on offshore platforms controlling flare systems. One cement plant I visited uses them for kiln temperature ramping—critical when thermal shock cracks refractory linings. They’re not for simple conveyor lines; this is for processes where a 5-minute outage triggers cascade failures.

Your procurement team will thank you

Let’s be real—nobody buys ABB for the lowest price. You’re paying for 365-day warranty coverage that actually includes firmware updates (unlike some brands). From my experience, the real value kicks in during brownfield upgrades: its native compatibility with older ABB 800xA systems typically avoids $20k+ in gateway costs. And when things go sideways? ABB’s support usually has a replacement unit shipped before you finish the trouble report.

Keeping it humming

Install it in standard 19″ cabinets with at least 100 CFM airflow—those dual Ethernet ports generate more heat than the single-port version. Always use shielded cables grounded at one end; I’ve seen noise issues kill analog signals in unshielded setups near VFDs. For maintenance: blow dust out quarterly (compressed air below 30 PSI), check terminal torque annually, and schedule firmware updates during planned shutdowns. One caveat: don’t attempt hot-swap on analog modules above 55°C ambient—it might glitch the signal.

Built to survive audits

CE, UL 61010-1, and ATEX Zone 2 certified out of the box. RoHS 3 compliant with full material declarations available. The 365-day warranty covers field failures but excludes damage from improper grounding—something inspectors always check. Fun fact: its conformal coating option (order code suffix “-CC”) passed 1,000-hour salt spray tests in a coastal desalination plant.

Getting it to your site

We keep 12 units in Rotterdam for EMEA rush orders—typically ships within 7 days. For new projects, expect 3-4 weeks if we need to configure I/O maps. Payment’s 50% upfront to lock production slots, balance before FedEx/UPS/DHL dispatch. One thing to note: if you need hazardous location certification, add 10 days for ATEX documentation review.
