1sna020264r0300 – diode baord 8way

Why Choose the TE Connectivity EM8D 8-Way Diode Module?

The TE Connectivity EM8D, manufacturer part number 1SNA020264R0300, is an industrial 8-diode module from the Entrelec Interfast electronic module range. Designed for control-panel and automation applications, it provides eight individual pass-through diodes in a compact open-module format, allowing diode functions to be integrated neatly into structured industrial wiring assemblies.

The EM8D uses eight diode channels arranged within a module measuring 50.8 mm in spacing. Individual diode paths can be used for functions such as signal isolation, steering and preventing unwanted current flow between compatible control circuits, eliminating the need to mount and wire multiple discrete diodes separately.

Designed for industrial rail mounting, the 1SNA020264R0300 uses screw-clamp terminal connections and is compatible with G32, TH 35-7.5 and TH 35-15 rails. Its modular design makes it particularly useful for machine controls, PLC interfaces, relay circuits and process automation installations requiring multiple diode functions in one organised assembly.

Eight Diode Channels for Industrial Control Circuits

Diodes allow electrical current to flow primarily in one direction and are commonly used in industrial control circuits for signal isolation, current steering and protection against unwanted reverse-current paths. Using multiple discrete diodes can increase wiring complexity, particularly where several control signals require the same function.

The TE Connectivity EM8D consolidates eight pass-through diodes into one rail-mounted interface module. This arrangement helps panel builders create cleaner and more serviceable control assemblies while providing convenient terminal access to each diode circuit.

Typical Applications

• Industrial control panels and electrical cabinets.
• PLC input and output interface circuits.
• Signal isolation and diode steering circuits.
• Relay and contactor control systems.
• Industrial machinery and machine-building applications.
• Process automation and instrumentation systems.
• Multi-signal DIN rail interface assemblies.
