Power indicator light , 16-way relay status indicator light (blue)
Module control terminal: There are 19 wire interfaces, all interfaces have terminal blocks, which is convenient for users to connect
If high level control is used: this signal should be connected to the negative pole of the power supply of the user control board
If low-level control is used: this signal should be connected to the positive pole of the user control board power supply
4. X1-X16: relay control interface,
If XM is connected to the negative/positive pole of the power supply: when this port is high (relative to XM), the corresponding relay is closed
Note: The isolated relay module is designed to adapt to the occasions where the electromagnetic environment is relatively harsh or the signal requirements are relatively high. If a complete isolation effect is to be achieved, the power supply of the user control board (that is, the reference power supply connected to XM) and the power supply supplied by the relay module (DC+/DC-) should be distinguished.
Relay output terminal: There are 48 wire interfaces, all interfaces have wiring terminals, which is convenient for users to wire
