Isolated input/output channels

The 16 relays are independent input / output channels, forming a one-to-one loop, all with independent transient surge protection circuits, and the standard resistive load current of each relay is 10A. The 1-11 loop is used for lighting, curtain control, etc., and the 12-16 loop is used for fan coil control. It can also indirectly support controlled sockets and air conditioning power control by controlling external AC contactors. The control of each loop can be configured through software. 15-16 circuit with 1NO and 1NC.

Relay cutoff and output limit

Each circuit of the dimming circuit has its own relay cut off to ensure that there is no thyristor leakage after the circuit is closed, which causes the lamp to flicker, and the range of the lowest starting voltage and the highest output voltage can be set through the software.

Multifunction IO channel

The device supports third-party switch panel access and debugging as a bus program, 22 dry contact inputs, 22 LED outputs, and an output voltage of 5 ~ 20VDC. The universal third-party button input port can be used in a variety of scene applications, and plays a role in custom style places such as homes, offices, and hotel rooms that require a large number of buttons and indicators. It also supports various third-party all-in-one hotel doorplates, doorbells, door and window magnets, etc. Simple debugging can complete cleaning / do not disturb / energy saving and other functions.
