The **ADS-BB-R** is a specific electronic component typically used as a **Remote Battery Box** or power supply module, often associated with proximity sensors, automatic door systems, or specific industrial controller setups (commonly found in the Optex or BEA catalogs for door automation). Below is a breakdown of the electronic parts, specifications, and functions of the ADS-BB-R. --- ### 1. Technical Specifications The ADS-BB-R serves as the "brain" or interface for sensor beams. It manages the power distribution and signal processing between the infrared heads and the main controller. | Feature | Specification | | :--- | :--- | | **Input Voltage** | 12 to 24V AC or DC | | **Current Consumption** | 160mA Max. | | **Output Contacts** | Form C Relay (N.O. / N.C.) | | **Relay Contact Rating** | 1A at 30V DC | | **Detection Channels** | Supports up to 2 pairs of sensor heads | | **Operating Temperature** | -20°C to +55°C (-4°F to 131°F) | --- ### 2. Key Internal Components The unit is composed of several critical electronic sub-assemblies: #### A. Microprocessor / Logic Controller The central integrated circuit (IC) processes the signals received from the infrared receiver heads. It determines if the beam is broken and manages the "Hold Time" logic. #### B. Form C Relay This is the physical mechanical switch that toggles the output state. * **Common (COM)** * **Normally Open (NO)** * **Normally Closed (NC)** #### C. Potentiometers (Adjustment Dials) The board usually contains small variable resistors used to adjust: * **Sensitivity:** Increases or decreases the threshold for beam interruption. * **Self-Diagnosis:** Some versions include a test cycle potentiometer. #### D. Connection Terminals Screw-down or plug-in terminal blocks provide the interface for: 1. **Power Input:** Terminals 1 & 2. 2. **Relay Output:** Terminals 3, 4, & 5. 3. **Sensor Input:** Specific ports for the Emitter (TX) and Receiver (RX) cables. --- ### 3. Wiring Configuration The following table outlines the standard wiring logic for the ADS-BB-R controller: | Terminal Number | Function | Description | | :--- | :--- | :--- | | 1 & 2 | Power Input | Connects to 12-24V source | | 3 | Common (COM) | The shared relay contact | | 4 | Normally Closed (NC) | Connected to COM when beam is clear | | 5 | Normally Open (NO) | Connected to COM when beam is blocked | --- ### 4. Operational Indicators (LEDs) The board features diagnostic LEDs to help technicians troubleshoot the circuit: * **Green LED:** Indicates the power is ON and the system is in standby. * **Red LED:** Indicates a detection event (the beam is broken and the relay has triggered). ---
