CEBEK 12V 4-Channel Isolated SPDT Relay Module
CEBEK 4-channel SPDT relay module with optocoupler isolation for 3–24V DC inputs. Ideal for automation & control systems.
The CEBEK 12V 4-Channel Isolated SPDT Relay Module provides reliable signal isolation and switching for various electronic applications. Through built-in optocouplers, this module ensures complete electrical isolation between control signals and outputs, offering protection against voltage spikes and interference.
Each channel activates when an input signal between 3V and 24V DC is applied, maintaining the output state until the input voltage drops to zero. The module features easy-to-use connection terminals and includes indicator LEDs for real-time status monitoring.
