DI/DO Module


DIO-52 is a DI/DO module that integrates wired devices into wireless networks to create automated responses and enhances security and convenience. With a digital input (DI) and a digital output (DO) connecting to wired devices, DIO-52 serves as a bridge of reliability and fast communication between a security system and wired devices.

DIO-52 turns the device connected to its DI point into the trigger of events, and its DO point into the responder of events. Open it, close it, turn it on, turn it off, wirelessly remotely activate or obtain data from devices that are hard to reach. Devices commonly connected are smoke detectors, PIR motion sensors, door/window contacts, garage doors, motorized shades, gates, or valves.

DIO-52 can be flexibly incorporated into new or existing smart home security systems, further improving process efficiency and safety for the entire home.
