Why Choose the TE Connectivity EM14DA Common Anode Diode Module?

The TE Connectivity EM14DA, part number 1SNA020267R0600, is an industrial 14-diode common anode module designed for signal interfacing, isolation and steering within electrical control and automation systems. Part of the established Entrelec Interfast Series 20.000, it integrates multiple diode circuits into a single open electronic module, providing a practical alternative to installing individual discrete diodes throughout a control panel.

The EM14DA uses a common anode configuration, with 14 integrated diodes arranged around a common positive connection. This configuration is useful for combining, isolating and directing control signals while preventing unwanted current paths between individual circuits, making the module particularly suitable for PLC interfaces, relay circuits and industrial machine control applications.

With 14 diodes integrated into a module with 50.8 mm spacing, the EM14DA provides a high density of diode functions while maintaining an organised panel layout. Screw clamp terminals provide secure conductor connections, while compatibility with G32, TH 35-7.5 and TH 35-15 rails enables straightforward installation in common industrial control cabinets.

Reliable Common Anode Diode Interfacing for Industrial Control

Diode modules are widely used in industrial automation systems to direct electrical signals, isolate interconnected control paths and prevent unwanted reverse-current flow. A common anode arrangement connects the anode side of multiple diodes to a shared point while retaining individual diode paths, providing a convenient architecture for suitable control and interface circuits.

The TE Connectivity EM14DA incorporates 14 common anode diodes into a dedicated DIN rail interface module. By centralising these diode functions within one assembly, it helps reduce discrete component wiring and supports cleaner, more serviceable control panel installations for PLC, relay and machine automation applications.
