Each relay applied to the 4-channel relay module has an "alarm drive logic". The alarm driver logic can be programmed with and Gate and or Gate logic and can take advantage of the alarm inputs (warning or danger) provided by any monitor channel in the frame or a combination of any monitor channel. The alarm driver logic application framework configuration software programming can meet the special needs of applications.
Note: 3500/34 TMR relay modules should be used when triple module redundancy (TMR) is required.
A "4-channel relay module" is an electronic component or device that contains four separate relay channels. Each channel can control a separate circuit or load.
A relay is an electromagnetic switch that can be turned on or off by electrical signals. In the 4-channel relay module, each channel has a corresponding relay, which can control the switching state of the channel through an external control signal.
4-channel relay modules are typically used to control the switching operation of multiple circuits or loads. For example, it can be used in lighting control systems, motor control, automation systems, etc. By using the relay module, you can control the switching of multiple circuits with a single control signal, enabling more complex control functions.
A 4-channel relay module usually has an input interface for receiving the control signal, and an output interface for connecting the controlled circuit or load. They may also have other features such as overcurrent protection, short circuit protection, status indication, etc.
The characteristics and functions of the specific 4-channel relay module may vary from product to product. If you need more information, you are advised to refer to the relevant product specifications or technical documentation.
