XL9535-K16V5 16-Channel 5V Relay Module IIC Relay Control Board with Optocoupler Isolation 10A Resistive Load Relay Driver 0-220V Control Expandable 16-Channel Interface SCL SDA
- 16-channel relay module provides control for 16 relay outputs through an IIC interface, supporting projects that need multiple switched circuits.
- Optocoupler isolation separates the signal side from the relay drive side, with the module using a dedicated isolation-based relay control scheme.
- The relay contacts support a maximum 10A resistive load and 7A inductive load, with load ratings stated for the relay outputs.
- The module accepts a control voltage range of 0-220V and uses a 5V relay power supply for the relay section.
- Three address control bits, A2, A1, and A0, allow address selection for expanding the IIC relay control arrangement.
- The module can expand to up to 8 IIC address sets, providing address configuration for larger relay control systems.
- Using four 16-channel IIC relay modules, the source states that up to 128 relays can be controlled through two IIC buses.
- VIN supports 3.3-5V signal power, while SCL and SDA provide the IIC clock and data connections with signal levels consistent with VIN.
- A J1 jumper connects or disconnects the signal power and relay power supplies, while GND is the shared input and output negative terminal.

Product Description:
The XL9535-K16V5 is a 16-channel 5V relay module with optocoupler isolation and IIC communication. It is designed to drive multiple relays through an IIC interface when a project has limited I/O ports and requires expanded relay control.
Core Selling Points:
Optocoupler isolation supports stable relay driving and separates the signal and relay power circuits. The module supports IIC expansion and provides three address control bits, A2, A1, and A0. Each relay supports a maximum load of 10A for resistive loads and 7A for inductive loads. The expandable design supports control of multiple relay modules through IIC communication.
Technical Specifications:
Model: XL9535-K16V5; relay channels: 16; relay power supply: 5V; communication interface: IIC; signal power supply: 3.3-5V; relay load: 10A maximum for resistive loads, 7A for inductive loads; working current: 100mA per piece; control voltage: 0-220V; relay terminals: NC, COM, and NO; address control: A2, A1, and A0; jumper: J1 for connecting or disconnecting signal power and relay power; pins: VIN, 5V, GND, SCL, SDA.
Before Purchase:
Confirm that your control system supports the IIC interface and that the available signal and relay power match the module requirements. Check the load type and current before connection: the stated ratings are 10A for resistive loads and 7A for inductive loads. Verify the required relay terminal configuration using NC, COM, and NO, and check that the application voltage is within the stated 0-220V control voltage range.
