The PISO-DA/PIO-DA series provides 16 digital input channels and 16 digital
output channels, and all signal levels are TTL compatible. The connection
diagram and block diagram are as follows:

The D/I Port can be connected to a DB-16P, which is a 16-channel isolated
digital input daughter board. The D/O Port can be connected to either a DB-16R
or a DB-24PR. The DB-16R is a 16 channels relay output board. The DB-24PR
is a 24 channels power relay output board.
