24V switch
From Rsewiki
Switch - intended for a 24V motor with no more than 3-4A continuous current
The box has a microprocessor controllable with a simple set of commands.
power on power off power help
"help" shows the list of commands, when using e.g. putty as a client.
"power" without parameter returns current setting as
"# power is 0\n" or "# power is 1\n"
The schematic is as in figure 1.
Figure 1. Schematics for 24V switch. The teensy is a 3.2 (the pin layout is here for a teensy 3.5). The MOSFET is mounted on the PCB, but 1W (5A) should be OK. The fuse is an automotive-fuse, that could be replaced with 10A if close to 5A use.
RHD
The RHD plugin is called 24v_switch and uses the following configuration in rhdconfig.xml
<switch24v enable="true" lib="24v_switch.so.1" critical="false" device="/dev/ttyACM0" debug="0"> </switch24v>
This should create a write variable for the MRC
