1sna020277r0000 – em4ddc
TE Connectivity EM8DDC 1SNA020277R0000 is an industrial screw clamp diode module designed for signal isolation, decoupling and interfacing in electrical control panels and automation systems.
Why Choose the TE Connectivity EM8DDC Diode Module?
The TE Connectivity EM8DDC, manufacturer part number 1SNA020277R0000, is an industrial screw clamp diode module designed for signal conditioning, isolation and interfacing within electrical control and automation systems. Part of the established Entrelec electronic module range, it integrates multiple diode functions into a single enclosed assembly for convenient installation within industrial control panels.
The EM8DDC provides an integrated diode arrangement for applications requiring signal decoupling, directional current control and isolation between control circuits. By incorporating multiple diodes into one module, it helps prevent unwanted feedback between connected circuits while reducing the wiring and installation work associated with individually mounted discrete diodes.
Designed for industrial panel applications, the EM8DDC features screw clamp terminal connections and an orange housing with approximately 101.6 mm spacing. It is suitable for mounting on G32, TH 35-7.5 and TH 35-15 rails, providing a practical interface solution for PLC systems, machinery controls and other industrial automation installations.

Reliable Diode Interfacing for Industrial Automation
Diodes are widely used in industrial control systems to control current direction, isolate signals and prevent unwanted feedback between interconnected circuits. Integrating these components into a dedicated diode module provides a convenient way to implement multiple diode functions while keeping electrical panel wiring organised and serviceable.
The EM8DDC combines its diode circuitry with industrial screw clamp connections in a rail-mounted format. This makes it a practical solution for panel builders and automation engineers who require repeatable diode-based signal interfacing without the additional installation and wiring associated with individual discrete components.
Typical Applications
- Industrial control panels and electrical cabinets.
- PLC input and output signal interfacing.
- Signal isolation and decoupling circuits.
- Machine control and automation systems.
- Collective signalling and indication circuits.
- Industrial process control installations.
