7.0 Relay Functional Schematic
The DLP-IO20 contains two latching relays. These are controlled by host software. The relay contacts
R1, S1, C1, R2, S2, and C2 are described in table 1. A functional view of how one of the relays works
is shown here.
Note: On power up of the DLP-IO20, the relay states will be unknown. Each can power up in either
the set or reset state. If a known initial state is required, the user will need to issue either a set or reset
command on power up.
Rev. 1.0 (January 2009)
100% duty cycle. The 5V power source provided by the host USB interface has limited power.
For this reason the amount of current drawn by the relay drivers MUST be limited to
there may not be enough current available to power the board, and the PC’s USB port could
be damaged.
