The SB401-50 is the entry-level basic model in the
SB401 series, featuring a standard design without explosion protection,
tailored for general non-hazardous industrial environments. As a core ESB bus
slave interface component, it connects FCUs and ESB Bus Node Units seamlessly,
working in tandem with EC401/EC402 coupler modules to ensure stable data
transmission. Unlike other SB401 models with advanced features, this basic
model focuses on reliable performance and cost-effectiveness, making it ideal
for routine industrial control tasks that do not require explosion protection
or ISA G3 compliance.
Adapter Matching & Connection Details (Sold
Separately):
•
Required Adapters: Dedicated ESB Bus Adapters —
A2EE1A-N (Connector unit for ESB Bus, G3 compatible) and A2EE1A-T (Connector
unit with terminator for ESB Bus, G3 compatible), both sold separately;
selection depends on ESB bus configuration (branching or termination).
•
A2EE1A-N Adapter: Designed for scenarios where the
ESB bus is branched off to the next SB401 module, serving as the connection
bridge between the SB401-50 module and the ESB bus. It ensures smooth signal
transmission between the module and other bus components, supporting the
module’s maximum 9 connectable units.
•
A2EE1A-T Adapter: Essential for scenarios where the
ESB bus is terminated, it terminates the bus signal to prevent reflection and
interference, ensuring the entire ESB bus system operates stably. The adapter
is easy to install, perfectly matching the SB401-50’s ESB bus connector (CN1)
for secure connection.
•
Adapter Features: Both A2EE1A-N and A2EE1A-T
adapters adopt a standard plug-and-play design, compatible with the SB401-50’s
interface, and feature durable construction to adapt to general industrial site
conditions, reducing maintenance time and operational costs.
