Product Details
Product Overview
The Schneider Electric ASMBKT185 serves as a critical passive component for maintaining signal integrity within Modbus Plus networks. Designed specifically for the Modicon Quantum, Premium, and Momentum automation platforms, these line terminators prevent signal reflection by matching the characteristic impedance of the transmission cable. This ensuring clean, error-free data communication across industrial distributed I/O systems. We supply the ASMBKT185 as 100% brand new, original factory hardware, sold in a convenient set of two to secure both ends of your network segment.

Engineering Advantages
-
Elimination of Signal Reflection: High-speed Modbus Plus data packets often reflect off the open ends of a trunk cable, creating "ghost" signals that corrupt data. The ASMBKT185 absorbs these redundant signals at the physical layer, ensuring the PLC processor receives clear, distinct pulses.
-
Broad Platform Interoperability: This terminator supports the entire Modicon family. Whether you manage a legacy Quantum rack or a modern Premium architecture, the ASMBKT185 provides the universal impedance matching required for the 1 Mbps Modbus Plus protocol.
-
Rapid Junction Box Integration: Engineers designed this part for direct insertion into the 990NAD23000 junction box. The plug-and-play mechanical fit reduces installation time during commissioning and eliminates the need for custom soldering or resistor splicing in the field.
-
Optimized for Multi-Drop Topologies: Modbus Plus supports up to 64 nodes per segment. The ASMBKT185 stabilizes these long-distance cable runs, particularly in environments with high electromagnetic interference, by maintaining the required voltage levels across the differential pair.
FAQs
-
Where exactly should I install the ASMBKT185?
You must install one terminator at the first physical node and one at the final physical node of the Modbus Plus trunk cable. Leaving an end unterminated will likely cause "Token Rotation" errors or intermittent communication loss.
-
Can I use a standard resistor instead of the ASMBKT185?
While the terminator contains a resistor, the ASMBKT185 provides the correct mechanical form factor and specialized impedance ratings required for Schneider junction boxes. Using non-standard components increases the risk of loose connections and network downtime.
-
Is this product sold as a single unit?
No, the ASMBKT185 comes as a Set of 2. This ensures you have exactly what is needed to terminate both ends of a standard network segment in one package.
-
How do I know this is a brand new Schneider part?
We ship every ASMBKT185 in its original Schneider Electric "PCE" packaging. Each set remains factory-sealed and includes the original manufacturer markings to guarantee it has never been used or refurbished.

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
