KEYSYS KEYSYS-RJ-16CH-AD Industrial Ethernet Module
The KEYSYS-RJ-16CH-AD serves as a backbone for industrial network infrastructures where reliability and high-density connectivity are non-negotiable. I’ve seen this module excel in environments like smart factories and power grid monitoring systems, where real-time data synchronization across 16 channels prevents bottlenecks during peak operations. Its ability to auto-negotiate between 10/100/1000 Mbps speeds makes it adaptable to both legacy systems and modern high-speed networks.

Applications & Compatible Systems
This module becomes particularly valuable when integrating distributed control systems (DCS) with SCADA networks – a recent client in the oil & gas sector used it to bridge their legacy PLCs with new PROFINET-enabled flow meters. We commonly pair it with:
- ABB AC800M controllers for power plant automation
- GE VMIVME-7807 modules in railway signaling systems
- Honeywell DCS cards for refinery process monitoring
Our Service Commitment
While the KEYSYS-RJ-16CH-AD itself is built for 24/7 operation, we back it with our global support network. Our 16 regional warehouses ensure 90% of orders ship within 24 hours – last month we replaced a faulty unit at a wind farm in Texas using stock from our Dallas facility. All purchases receive:
- 1-year extended warranty (beyond standard 6-month)
- Free technical consultation with our engineers
- Price matching for bulk orders
