KET-WIOM-845 wireless IO module

General The KET-WIOM-845 wireless input/output module (hereinafter referred to as the module) is suitable for installation in public places, factories and other environments. When there is a Fire Alarm, the module can send an alarm signal to the controller through wireless communication technology after receiving the closing signal, or it can output the closing signal to connect to other equipment. Features 1. Adopting 470MHz wireless communication technology, no need to pre-buried wiring, easy and quick engineering installation; 2. With battery low-voltage detection function, it can reflect the battery power status in time; 3. Use microprocessor to realize signal processing, and use digital signal to communicate with controller, work stably and reliably, and have good suppression ability against electromagnetic interference.
