The TE Connectivity EM30DC 1SNA020271R0200 is an industrial 30 double diode module designed for signal isolation, grouping and interface functions in electrical control and automation systems. Part of the established TE Connectivity / Entrelec electronic module range, it consolidates multiple diode circuits into a single DIN rail-mounted assembly for cleaner and more efficient panel wiring.
The EM30DC uses a common-cathode diode configuration, providing a practical solution where numerous diode-isolated signals need to be handled within one control-panel module. Its high connection density makes it particularly useful for PLC interfacing, alarm systems, indication circuits and other applications where unwanted feedback between control signals must be prevented.
Designed for industrial panel installation, the EM30DC features screw-clamp terminal connections and is suitable for mounting on G32, TH 35-7.5 and TH 35-15 rails. With a module spacing of 101.6 mm and a net weight of approximately 110 g, it provides a robust, integrated alternative to installing numerous individual discrete diodes.
Diode modules are used throughout industrial automation systems to control current direction and electrically decouple interconnected signals. This helps prevent feedback from one circuit into another and enables functions such as signal grouping, common alarm generation, indication control and PLC input or output interfacing.
The EM30DC integrates a large number of diode functions into one industrial module, reducing the need to mount and wire individual discrete diodes throughout a control cabinet. Its common-cathode arrangement, screw-clamp terminals and DIN rail mounting provide a practical solution for creating organised, serviceable and space-efficient interface circuits.
