Product Description:
The PCLD-782B digital input daughterboards feature highvoltage (>
1500 V DC ) optical isolation on all inputs. The new PCLD-782B provides
either 16 or 24 channels, depending on the connector you use. The
PCLD-782B’s 20-pin connector lets you access 16 channels, similar to
the PCLD-782. The PCLD-782B also provides a 50-pin Opto-22 connector
with access to 24 channels. Both cards have on-board screw terminals
for easy input wiring. Opticallyisolated signal conditioning provides
isolation between separate channels, as well as between each input
channel and the PC. This isolation prevents floating potential and
ground loop problems while protecting the input lines from potentially
damaging fault conditions. A red LED on each input channel indicates
its status. If the input signal is high, the LED is on. You can
configure each channel to work in either isolated or non-isolated mode.
A variable resistor adjusts the threshold level for all 24 isolated
input channels simultaneously.
