How to Choose a Smart Locker Electromagnetic Lock Control Board

Selecting a lock control board for a parcel locker requires comprehensive consideration of key parameters such as channel capacity, communication method, power supply compatibility, feedback function, and reliability design. Below, we'll explain how to choose the right lock control board from several perspectives.

1. Number of Channels and Cascading Capability

Choose a board based on the number of slots in the parcel locker. Common models include 12-channel (DEWO SK12), 24-channel (SK24), 40-channel (SK40), and 48-channel (SK48). A 10% margin should be reserved for expansion needs.

RS-485 interface boards typically support cascading up to 32 boards, making them suitable for scenarios such as multiple cabinets and large parcel locker networks.

2. Communication Interface Type

The RS485 communication interface is relatively common, offering advantages such as low cost and strong interference resistance, making it suitable for all cabinet types. Networking requires a host computer.

Communication interfaces such as 4G/RJ45/BT. If wireless communication is onboard, the cost is relatively high. Furthermore, certain locations, such as subway stations and basements, are not ideal for wireless communication due to high latency and signal issues.

3. Power Supply and Electrical Parameters

For voltage compatibility, a control board that supports both 12V and 24V is preferred. This makes it easier to adapt to electromagnetic locks. Currently, 12V electromagnetic locks (such as the DWEO S150/S220) are still common on the market. Furthermore, considerations such as drive current and unlocking time should be considered.

4. Lock Status Feedback and Object Detection

Lock status feedback is essential. This function monitors the door lock status (open/closed) in real time to prevent misoperation or missed faults.

Some users and scenarios require object detection, which requires a lock control board with infrared interface support (such as the DEWO SK12/SK24). This infrared detection interface can detect the presence of an object, but the cost is relatively high.

5. Lock Control Panel Protection Mechanism and Reliability Design

Consideration should be given to circuit protection, reverse polarity protection, surge protection (lightning protection), and isolation.
DEWO lock control boards utilize industrial-grade conformal coating for effective protection against moisture, dust and corrosion. The operating temperature range is -20℃ to +70℃

6. Scalability and Compatibility

Depending on the usage scenario, additional peripherals such as light box control, fan, and temperature and humidity control may need to be considered. Furthermore, lock control panel compatibility and program upgrades are crucial.

DEWO has its own R&D team and has customized lock control panels for various cabinets for many large enterprises. We support hardware and software customization of lock control panels. We also support command modification, making it a seamless replacement for any brand of lock control panel. We offer smart cabinet kits including electromagnetic locks, lock control panels, Touch Screens, Android/Windows all-in-one devices, barcode scanners, and customizable cables.
