Phoenix UPBV/UP/UIK/UEGM/UDK Series Terminals & Functional Modules Selection Guide

Phoenix this batch of products covers 12 sub-series including UPBV/UP (basic wiring terminals), UIK/UISLKG (high-current terminals), UEGM/UEGH (relay/functional modules), and UDK/UDMTK (multi-functional terminals with marking/grounding functions). The wire cross-section ranges from 2.5mm² to 35mm², integrating color coding, grounding protection, signal switching, and circuit marking functions. It is widely used in industrial control cabinets, power distribution systems, and automation equipment for standardized circuit connection and management.

1. Core Model Classification & Product Descriptions

The series is categorized by product function for clear matching of application needs, with key parameters including wire cross-section, pole count, functional attributes, and color coding:

1.1 Basic Wiring Terminals (UPBV/UP Series)

General-purpose wiring terminals, with UPBV supporting color coding for circuit identification, and UP being a cost-effective universal model.

1.2 High-current Terminals (UISLKG/UIK Series)

Designed for medium-high power main circuit connection, supporting 16mm²/35mm² large wire cross-sections.

1.3 Special Interface & Auxiliary Terminals (UKB/UHK/UHSK/UGSK Series)

With FS interface or specialized structure, suitable for signal transmission and function expansion between terminals.

1.4 Relay & Functional Modules (UEGM/UEGH/UEG Series)

Integrates relay switching, signal isolation, and other functions, suitable for industrial control system signal conversion.

1.5 Multi-functional Terminals (UDMTK/UDK Series)

Integrates marking, grounding, testing, and other functions, with color coding for circuit identification.

2. Quick Interpretation of Model Naming Rules

The naming logic of this batch of products follows Phoenix's standardized specification, with each segment corresponding to clear product parameters:

3. Core Advantages of This Batch of Products

1. Full-spec Coverage & Strong VersatilityCovers wire cross-sections from 2.5mm² to 35mm², pole counts from 1 to 10 poles, meeting the connection needs of low-power signal circuits, medium-power control circuits, and high-power main circuits.
2. Clear Color Coding & Easy MaintenanceBlue (signal), yellow-green (grounding), and red (power) color-coded models realize visual circuit classification, reducing maintenance errors in complex control systems.
3. High Integration of Multiple FunctionsUDK series integrates grounding, marking, and testing functions; UEGM series integrates relay switching and signal isolation, eliminating the need for additional external components and simplifying circuit layout.
4. Strong Compatibility & Easy InstallationMost models support standard rail mounting (e.g., SO35), compatible with mainstream industrial control cabinet layouts; special interface models (FS) facilitate signal transmission between different devices.

4. Product Selection Suggestions

1. Select by Wire Cross-section & Current Requirements
   • For low-power signal circuits (2.5–4mm²): Choose UPBV/UDK series models (e.g., 3045253, 2775223).
   • For medium-power control circuits (6–16mm²): Select UP/UISLKG 16 series models (e.g., 3060649, 0443052).
   • For high-power main circuits (35mm²): Adopt UIK 35/UISLKG 35 series models (e.g., 3006302, 0443065).
2. Select by Functional Requirements
   • For circuit identification & labeling: Choose color-coded UPBV/UDMTK models (e.g., 3045758, 3101113).
   • For grounding protection: Select PE suffix models (e.g., 3045253, 2775184).
   • For signal switching & isolation: Use UEGM series relay/isolation modules (e.g., 2757322, 2766850).
   • For on-site circuit testing: Choose UDK 4-TG models with test points.
3. Select by Interface & Expansion Needs
   • For signal transmission between terminals and external devices: Select FS interface models (e.g., 1960013, 2017224).
   • For terminal function expansion: Use UHSK/S/UGSK/S auxiliary terminals (e.g., 0704076, 0305080).
