The **SVB-FZ-R/Q** is a specific technical configuration within the **SMC SV series** of solenoid valve manifolds. This designation typically refers to a sub-assembly or a base-mounted interface designed for industrial automation and pneumatic control. ### Component Breakdown The part number can be broken down into specific electronic and mechanical modules: | Component Identifier | Description | Function | | :--- | :--- | :--- | | **SV** | Series Series | Multi-pin or fieldbus compatible solenoid valve series. | | **B** | Base Mounted | Indicates the valve is mounted on a manifold base rather than being pipe-connected. | | **FZ** | Connector Type | Represents a specific electronic interface, often a **D-sub connector** or a **flat cable** interface for parallel wiring. | | **R/Q** | Technical Spec | **R** usually denotes an external pilot specification; **Q** often refers to specific CE/UKCA compliance or global standards. | --- ### Core Electronic Characteristics The electronic parts of this assembly focus on signal distribution and power management for solenoid actuation. #### 1. Integrated Circuit (PCB) The internal manifold block contains a small Printed Circuit Board (PCB) that distributes power from the central connector (D-sub or Fieldbus) to individual solenoid coils. - **Polarity Protection:** Most modules include diodes to prevent damage from reverse wiring. - **Power Consumption:** Optimized for low wattage (typically **0.6W to 0.1W** per coil) to allow high-density mounting. #### 2. Solenoid Actuators The solenoids are the "muscles" of the electronic assembly: - **Voltage:** Standard 24V DC (though 12V DC variants exist). - **Response Time:** Rapid switching (approx. 10-30ms) managed by the electromagnetic coil. - **Indicator Lights:** Features integrated **LEDs** to show the ON/OFF state of each valve for troubleshooting. #### 3. Protection Circuits The electronic assembly includes: - **Surge Voltage Suppressors:** Prevents back-EMF spikes from damaging the PLC (Programmable Logic Controller) outputs when the solenoid is de-energized. - **IP Rating:** The electrical interface is usually rated **IP67**, meaning it is dust-tight and protected against temporary immersion in water. --- ### Comparison of Connection Interfaces Depending on whether the "FZ" refers to a specific wiring block, the electronic interface changes: | Feature | Parallel Wiring (D-sub) | Serial Wiring (Fieldbus) | | :--- | :--- | :--- | | **Wiring Complexity** | High (Individual wires per valve) | Low (Single data cable) | | **Data Feedback** | No (Output only) | Yes (Diagnostic data/Short circuit alerts) | | **Max Valves** | Typically up to 24 stations | Up to 128 (depending on protocol) | --- ### Technical Specifications Summary - **Rated Voltage:** 24 VDC (+/- 10%) - **Power Consumption:** 0.65W (standard type) / 0.1W (with power-saving circuit) - **Ambient Temperature:** -10 to 50°C - **Lead Wire Entry:** D-sub connector, Flat ribbon cable, or Terminal block. ---
