Function description Remarks
GND1
Ground
Ground
OUT
Output signal
OUT is the module signal output interface; drain output; normal
state: high-impedance state; supports a maximum of 30V
external input
IN1 and
IN2
Input signal
IN1 and IN2 are module signal input interfaces; pull-up input;
the external device is required to adopt drain output; the internal
10K resistance pulls up to 1.8V voltage.
485A1
and
485B1
RS485_1 interface
RS485 half-duplex communication interface. It supports
simultaneous connection with 32 devices in one bus, supports a
maximum transmission rate of 10Mbps, and fully complies with
the electrical specifications of RS485 and RS422 serial
protocols.
The hardware can be configured as: RS232 interface

Reserved
(interface RS232)
By default, the configuration is not defined.
485A2
and
485B2
RS485_2 interface
RS485 half-duplex communication interface. It supports
simultaneous connection with 32 devices in one bus, supports a
maximum transmission rate of 10Mbps, and fully complies with
the electrical specifications of RS485 and RS422 serial
protocols.
VCC and
GND2
Power interface
VCC and GND2 are respectively the positive electrode and
negative electrode of the DC input. The DC supply voltage
ranges from 5V to 26V. 12V 1A DC power supply is
recommended.
