IM502 Input module

DC24V power output with reset power off function

◆ Product Features

The T+, T-alarm bus and the DC24V power bus are non-polar designs and can be regarded as the same fire detector connecting to the alarm buswhich is convenient for construction and flexible in use. The alarm bus is isolated from the DC24V power bus and enhances the anti-jamming performance.
Can detect the input signal and DC24V power line break, short circuit fault signal.
Its DC24V power output has a reset power-off function, so that the switching device in the alarm state can be reliably reset when the controller is reset.
