NOTICE

Ÿ   DOUT9 and DOUT10 are used to control relay K1 and K2 respectively, which are internal encapsulated interfaces. If you use relay for power supply or other applications, you can use the COM, NC, NO interfaces directly on the external expansion board after connecting it to Dobot M1. If you have to debug the relay K1 and K2, you can debug OUT09 and OUT10 on the M1Studio > I/O Assistant page. For details, please see 6.10.6 Example of Relay Connection.

Ÿ   All input and output interfaces of the Dobot M1 only can be used for signal control and cannot be regarded as power supply. You can use relays on the external expansion board for power supply. Take relay K1 as an example, the circuit diagram is shown in Figure 4.5.
