DIN rail mounting

“Modular” equipment is flexibly installed and applied in the actual environment. The system is equipped with standard 35mm DIN rail mounting, providing convenient installation and maintenance for users.

S-Net bus modular design

The module is designed for the MCU pure hardware architecture and has local data processing and channel control. The overall power consumption of the module is low and the task processing is timely. The module communicates via the bus to ensure the stability and reliability of data transmission. Each module has a corresponding physical address. The DIP dialer can be used to set the address of the module to ensure that each module can operate correctly and accurately receive and execute commands transmitted from the bus.

Multifunction IO channel

SDR-DCI3528 is a diversified and compact module that supports third-party switch panel access and debugging as a bus program, supports up to one active 5~24VDC input, 35 inputs are dry contact inputs, and 28 output indicator outputs The output voltage is in the range of 5~20VDC, and the output current is more than 100mA. The total output is about 400mA. Universal third-party button input ports can be used for a variety of scene applications, functioning in custom style locations such as homes, offices, and hotel rooms that require a large number of buttons and indicators.

High compatibility

The module supports various types of third-party all-in-one hotel house numbers, doorbells, card panels, and sensor access. Simple debugging can complete the functions of sweeping/do not disturb/energy saving/power taking.
