Triconex 4201N is a Nuclear 1E qualified Remote Extender Module for the Tricon v10 system and is technically referenced to standard model 4201. It is installed at the remote RXM chassis location and uses multimode fiber with ST connectors. The RXM data path operates at 375 kbit/s with a multimode link limit of 2 km. A complete remote RXM set contains three identical modules for channels A, B and C. Each remote location uses six fiber connections, with one transmit and one receive path per channel.
The 4201N extends the triplicated Tricon I/O bus from a primary installation to an engineered remote chassis while maintaining ground-loop isolation between locations. Its optical architecture supports reliable separation of safety-system equipment across the plant. The module should be matched with the correct remote RXM role and must not be confused with a primary extender or a complete three-module set. Procurement teams should confirm the installed revision, fiber arrangement and qualification records before replacement. This clear identification helps maintenance teams source the correct Triconex remote extender for an existing safety platform.
Extends the triplicated Tricon I/O bus to a remote chassis in a Tricon v10 Nuclear 1E system.
Connects a remote RXM chassis across a multimode fiber link while maintaining ground isolation between locations.
Supports remote Tricon chassis placement over multimode fiber at distances up to 2 km from the primary location.
We verify the label, condition and supplied scope, then provide available photos or test evidence before dispatch.
We arrange shipment immediately after payment is received and normally provide tracking as soon as the parcel is collected.
4201N identifies one Remote Extender Module; 4201-3N identifies the complete three-module set.
Please confirm the installed revision, remote RXM role, multimode ST fiber and system qualification records.
It is protected with antistatic and shock-resistant packing, then placed in a reinforced shipping carton.
A 12-month warranty is provided, and the relevant official technical literature can be supplied with the order.

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.
We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.
An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.
Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.
A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
