A3. DB-8225
The DB-8225 provides an
on-board CJC
(Cold Junction Compensation)
circuit for thermocouple measurement and a
terminal block
for easy
signal connection and measurement. The CJC is connected to AD
channel_0. The PCI-1002 series can connect CON3 directly to DB-8225
through a 37-pin D-sub connector. Refer to “
DB-8225 User Manual
” for
details.
A3. DB-16P Isolated Input Board
The DB-16P is a 16-channel isolated digital input daughter board. The
optically isolated input of the DB-16P consists of a bi-directional
optocoupler with a resistor for current sensing. You can use the
DB-16P to sense DC signal from TTL levels up to 24 V, or use the
DB-16P to sense a wide range of AC signals. You can use this board to
isolate the computer from large common-mode voltage, ground loops and transient voltage spikes
that often occur in industrial environments.
