SK200PRO is an industrial wireless single switch control module. It consists of SK200PRO-TX ( transmitter module ) and SK200PRO-RX ( receiver module ). The transmitter can choose a module with a power of 100mW, 1W or 5W as required. The wireless design uses LoRa technology, which has highly efficient receiving sensitivity and strong anti-interference performance. It has better communication distance and receiving sensitivity than FSK and GFSK modulation. In the one-to-many working mode, in cooperation with the MESH network that comes with the receiving end, it can form a network transmission without blind spots and distance restrictions. The module provides single signal input and single control output interface. It has the characteristics of simple interface and reliable operation. Users can combine our PC interface to configure and modify the internal parameters of the module. The parameters of the receiver can be wirelessly configured by the transmitter, which is convenient for online changes. Multi-pair simultaneous communication will not interfere with each other, and it is flexible and convenient to use.

Specification:

The electrical parameters of SK200PRO-TX module are as follows:

The electrical parameters of SK200PRO-RX module are as follows

Input and output:

1) Input and output

CS pin of the transmitter is the input. With a built-in pull-up, disconnected CS pin or givenahighlevel (3.3V) means high level input, Short the CS pin to the ground GND means lowlevel input, andthe relay of the receiver module will correspondingly be open or close.

Note1: You can contact us to get the relay to reverse state Note2: After power on reset of the receiver, the default state of the relay is close. ( Usercanchange the default state with our PC software )

2) Operating mode

There are several working mode for user to choose through our PC software. Real Time Mode: In this mode, both the transmitter and receiver are ready all the time. The receiver will synchronizetherelay out immediately when the input state of the transmitter is changed. Every 60s, the transmitterwillsend synchronize signal to the receiver, the receiver is lost link and the relay of receiver will changetodefault state after no synchronize signal received for consecutive 3 times. User can set this 60stoothertime period with our PC software. Low Power Mode: In this mode, the transmitter can work in low power mode. Most of the time, the transmitterissleeping to save power consumption. It will be awaken and send signal out once the input state(CSPin) is changed. In this mode, no lost link indication in the receiver.

Note: 1 The relay state when lost link can be changed by PC software 2Time interval can be modified by PC software 3 The lost link function is available in real time mode only. In order to prevent thereceiverfrom working uncontrollably and causing the equipment to work abnormally, the receiverwillopen or close the relay automatically if it does not receive the synchronization signal withinaspecified time. 4 Transmitter and receiver must work in the same mode. *5 Factory default working mode is Real Time mode.

2) Operating mode There are several working mode for user to choose through our PC software. Real Time Mode: In this mode, both the transmitter and receiver are ready all the time. The receiver will synchronizetherelay out immediately when the input state of the transmitter is changed. Every 60s, the transmitterwillsend synchronize signal to the receiver, the receiver is lost link and the relay of receiver will changetodefault state after no synchronize signal received for consecutive 3 times. User can set this 60stoothertime period with our PC software. Low Power Mode: In this mode, the transmitter can work in low power mode. Most of the time, the transmitterissleeping to save power consumption. It will be awaken and send signal out once the input state(CSPin) is changed. In this mode, no lost link indication in the receiver.

3) MESH networking When one transmitter controls multiple receivers, some receivers may not receive control signalsdue to the range. To solve this problem, SK200PRO comes with MESH networking function. Thereceivers can be organized as MESH network to extend the longer range.
