The **KADS-2Z-R** is a specific model of an **Industrial Power Relay**, typically used in automation control systems, PLC interfacing, and motor control circuits. It is designed to act as an electrically operated switch, allowing a low-power signal to control a high-power load. --- ### 1. Technical Specifications The following table outlines the primary electronic and physical characteristics of the KADS-2Z-R: | Feature | Specification | | :--- | :--- | | **Contact Form** | 2Z (DPDT - Double Pole Double Throw) | | **Contact Rating** | Usually 5A or 10A (Model dependent) | | **Coil Voltage Options** | 12VDC, 24VDC, 110VAC, or 220VAC | | **Mounting Type** | Plug-in (compatible with DIN Rail sockets) | | **Indications** | Built-in LED status indicator | | **Manual Override** | Often includes a mechanical test button | --- ### 2. Key Internal Components The KADS-2Z-R consists of four main functional electronic parts: 1. **Electromagnetic Coil:** When electricity flows through this coil, it generates a magnetic field. This is the "input" side of the component. 2. **Armature and Spring:** The magnetic field pulls a metal armature toward the coil. When power is removed, a spring pulls the armature back to its original position. 3. **Contacts (2Z Configuration):** The "2Z" designation means it has two sets of changeover contacts. Each set includes: * **COM (Common):** The moving part of the switch. * **NC (Normally Closed):** Connected to COM when the relay is OFF. * **NO (Normally Open):** Connected to COM when the relay is ON. 4. **Protection/Feedback (LED):** An integrated LED (usually green or red) provides a visual confirmation that the coil is energized, aiding in troubleshooting. --- ### 3. Connection Diagram (General Logic) In a typical installation using a 24VDC control signal, the wiring logic follows this structure: ```text [Input Side] Terminal 13/14: Coil Power (+/- 24VDC) [Output Side - Pole 1] Terminal 9: Common (Line In) Terminal 1: Normally Closed (NC) Terminal 5: Normally Open (NO) [Output Side - Pole 2] Terminal 12: Common (Line In) Terminal 4: Normally Closed (NC) Terminal 8: Normally Open (NO) ``` --- ### 4. Applications * **PLC Interfacing:** Using a small 24V PLC output to switch 220V motors or solenoids. * **Signal Isolation:** Protecting sensitive controllers from voltage spikes in the load circuit. * **Logic Operations:** Using multiple relays to create "AND/OR" hardware logic gates.
