Role of input and output modules

Fire alarm, the alarm controller output module plc needs to start linkage external control devices such as smoke control valve, sending valve, fire shutter doors, fans, alarm, etc., and to accept the action device answer.
Output modules connected to the bus loop controller can be installed in the vicinity of the control device can also be installed in the floor inside the terminal block. Electronic writing code, you can live encoding. Ji-output control logic output modules can be completed according to the project situation programming. When the controller receives the alarm signal to the detector, based on pre-programmed into the program, the controller will be linked via the bus control signal to theplc analog output module, the output module needs to start linkage firefighting equipment; action after the device will accept a signal answer.
