2 in 1 RS485/TTL232 4 Channel MOS Transistor 8 Channel TTL Level Output Module

1. Use high-quality materials with guaranteed quality. 2. It has RS485 and TTL232 interfaces, which are independent of each other and can be used simultaneously. 3.4 channel MOS transistor output (O1-O4), maximum driving capacity of 3A, NPN low-level output, capable of driving resistance and inductance loads such as LED relays, low-power motors, solenoid valves, etc. 4.8 channels of 5V TTL port output (O5-O12), with a maximum drive capacity of 10MA. Default Low Level Output (NPN), which can be set to High Level Output (PNP) by command.

5. For more stable operation, the power supply must be greater than 2 times the load power, and if it is an inductive load, it must be greater than 3 times. By default, the AT command and Modbus RTU command can be used simultaneously. The two pads of M0 are welded together and can only be used with Modbus RTU commands
