1sna031805r1200 – 230vac opto w/led

Why Choose the TE Connectivity BNMS T230V-1 230V AC Input Optocoupler Plug?

The TE Connectivity / Entrelec BNMS T230V-1, manufacturer part number 1SNA031805R1200, is a compact 230 V AC input optocoupler plug designed for industrial control and automation applications. It provides an electrically isolated interface between a 230 V AC control signal and compatible low-voltage electronic circuitry, making it particularly useful for PLC and machine-control signal interfacing.

The BNMS T230V-1 is specifically configured as an input optocoupler for 230 V AC and provides an electronic output rated at 58 V DC / 30 mA. Optical coupling provides galvanic separation between the input and output circuits, helping prevent a direct electrical connection between the higher-voltage field signal and sensitive control electronics.

Designed as a yellow plug-in module for compatible Entrelec Interfast MS interface assemblies, the 1SNA031805R1200 offers a convenient modular approach to AC signal isolation. Its plug-in construction simplifies replacement and maintenance while supporting compact, organised control-panel layouts.

Isolated 230 V AC Signal Interfacing for Industrial Controls

An optocoupler transfers a control signal across an electrically isolated barrier using light rather than a direct conductive connection. This allows a higher-voltage field circuit to communicate with compatible electronic control equipment while maintaining electrical separation between the two sides of the interface.

The TE Connectivity BNMS T230V-1 is configured for 230 V AC input signals and provides a 58 V DC / 30 mA electronic output. This makes it a practical interface component for PLC systems, machine controls and industrial automation equipment where isolated detection of mains-level AC control signals is required.

Typical Applications

• PLC input signal isolation.
• 230 V AC industrial control circuits.
• Machine-building and OEM automation systems.
• Industrial control panels and electrical cabinets.
• Process-control and instrumentation systems.
• AC field-signal interfacing.
• Compatible Interfast MS interface assemblies.
