1sna020268r1700 – em30da 30 way double diode

Why Choose the TE Connectivity Entrelec EM30DA Diode Module?

The TE Connectivity Entrelec EM30DA, manufacturer part number 1SNA020268R1700, is a 30-diode common-anode module designed for industrial control, automation and interface circuits. Part of the Entrelec electronic module range, it combines multiple diodes and screw-clamp connections in a single rail-mounted assembly, providing an organised alternative to wiring individual discrete diodes within a control panel.

The EM30DA provides 30 diodes with a common-anode configuration in a module with 101.6 mm spacing. This arrangement is useful where numerous signals need diode isolation, steering or decoupling while sharing a common electrical point, helping reduce component count and simplify panel wiring.

Designed for industrial terminal systems, the EM30DA uses screw-clamp connection technology and can be mounted on G32, TH 35-7.5 and TH 35-15 rails. Its integrated format makes it particularly suitable for PLC interfaces, automation systems and machine-control applications requiring multiple diode functions in a compact, serviceable assembly.

Integrated Common-Anode Diode Connections for Control Systems

Diodes are frequently used in industrial control circuits for signal isolation, decoupling and steering. Where many diode functions are required, installing individual components can increase wiring complexity and consume valuable panel space. A multi-diode module groups these functions into a structured terminal assembly that is easier to incorporate into an industrial control system.

The TE Connectivity Entrelec EM30DA provides 30 integrated diodes in a common-anode arrangement. The 101.6 mm screw-clamp module can be installed on common industrial rail formats, providing panel builders with a convenient solution for applications requiring a large number of common-anode diode connections.

Typical Applications

• Industrial control and automation panels.
• PLC input and output interface circuits.
• Signal isolation and decoupling circuits.
• Diode steering and logic arrangements.
• Machine building and OEM control systems.
• Industrial signalling and interlocking circuits.
• Rail-mounted electronic interface assemblies.
