32-Channel Lock Control Board for Smart Lockers — RS485, 9-24V Industrial High-Density
OEM lock control board with 32 lock outputs on one PCB — for high-density lockers (parcel, BOPIS, pharmacy). RS485 + IO + relay, -40°C to 85°C industrial grade.
Product Overview
The 32-channel RS485 lock control board is a core electronic control board for smart locker OEM projects. It manages 32 independent electric lock channels, communicates through RS485, and helps the main Android terminal or upper computer system open doors, read lock status, detect door magnetic status, and report abnormal conditions. It is built for high-density cabinet sections where a larger number of doors must be managed from one board. This helps reduce board count, wiring complexity, and installation space for parcel locker banks, campus lockers, retail pickup walls, and multi-door service cabinets. For integrators, the value is not only the number of channels but also predictable electrical behavior: 9V to 24V DC working voltage, 9V to 18V DC lock voltage, less than 3A unlocking current, low static current at 12V, and an industrial operating range from -40°C to 85°C. The board also includes reverse polarity protection, RS485 misconnection protection, lock short-circuit protection, surge protection, ESD Level 3 protection, waterproof and dustproof design, real-time channel indication, address configuration from 1 to 199, and support for multi-board cascading. It is suitable for cabinet makers that already have metal structure capability and need reliable control electronics, and for software companies that want to connect physical locker doors to their own cloud, mobile app, OMS, POS, or local platform.
Where It Fits in a Smart Locker System
This component is designed for OEM cabinet builders, smart locker integrators, and software platform teams that want to build their own parcel lockers, pickup lockers, laundry lockers, storage lockers, vending lockers, charging lockers, or internal asset lockers. It is not a complete cabinet by itself; it is a core control part used inside a complete smart locker solution.
- Smart parcel lockers and package pickup stations
- Self-service order pickup lockers for retail and staff handover
- Smart laundry and shoe service lockers
- Storage, file, tool, and asset lockers
- Smart vending cabinets and phone charging lockers
Integration Workflow
A typical integration connects the customer cloud, app, OMS, POS, or local management platform to the Android terminal or main controller. The terminal communicates with the lock control board through RS485, and the board drives each electromagnetic lock while returning lock status, door magnetic status, alarm information, and fault feedback to the upper system.

OEM Buying Guidance
Before ordering samples or bulk quantities, confirm the cabinet door count, power supply plan, lock voltage, cable length, main controller type, communication protocol, address plan, and whether you need software support, API documents, custom firmware, or a complete screen plus board plus lock kit.
- Confirm cabinet door quantity and channel plan before selecting board capacity.
- Confirm 12V or 24V power design, lock voltage, cable routing, and installation space.
- Confirm whether your software team needs protocol documents, API support, sample testing, or firmware cooperation.
- For new OEM projects, evaluate the complete screen + lock control board + electromagnetic lock kit to reduce compatibility risk.
