Can the 900-2RS option board be used with the PS902 power supply?

The 900-2RS option board can be used with the PS902 power supply.  The PS902-2RS power supply option board combination is the basic power source that is used to operate either one or two of the current QEL+ exit devices.  We can use the 900-2RS board with this power supply today because the current QEL+ motor no longer requires a communication channel to operate.  Unlike the old/obsoleted QEL motor which required the 900-2Q option board supplying both voltage and communications to work.
