General Description
All PowerDAQ boards can control solid-state relays when
combined with PD-SSR series modules, which are available as
inputs for sensing changes or as outputs to send TTL signals
for control purposes.
The PD-SSR senses logic levels and sends results to the
PowerDAQ DIO subsystem. It also detects and reports opens
and shorts. PD-SSR modules plug into a 16-channel
backplane (PD2-DIO-BPLANE-16).
Up to four backplanes can connect to the PowerDAQ digital
distribution panel (PD2-DIO-CONN64-4 or PDL-DIO-
CONN64-4), which distributes 64 lines into four groups of
16. For the PD2-DIO-128 you can use up to two PD2-DIO-
CONN-64-4 panels.
The PD2-DIO-CONN64-4 and PDL-DIO-CONN64-4 are DIN
mountable and also has 5V, digital ground, latch and update
signals.
The PowerDAQ Software Suite includes extensive software
support for controlling and reading the digital signal-
conditioning products. Support is included for Visual C++,
Delphi, Visual Basic, Borland C++, LabVIEW, TestPoint,
DASYLab, Agilent VEE and DIAdem software.
