The role of output modules plc

Fire alarm, the alarm controller output module needs to start by the linkage of external control devices, such as ethernet module plc control valve, sending valve, fire shutter doors, fans, alarm, etc., and to accept the action device to answer.
output module plc connected to the bus loop controller can be installed in the vicinity of the control equipment can also be installed in the plc high-speed counting module inside the terminal module. Electronic writing code, you can live encoding. Ji-output control logic output module 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 procedure, the controller via the bus output control signal to the interlocking modules, output modules linkage needs to start fire-fighting equipment; action after the device receives a reply signal.
