Introduction
PCLD-780 and PCLD-880 universal screw-terminal boards provide convenient and reliable signal wiring for PC-LabCard⢠products with 20-pin flat-cable connectors. PCLD-880
is also equipped with a DB37 connector to support PC-LabCard⢠products with DB37 connectors.
PCLD-780 and PCLD-880 let you install passive components on the special PCB layout to construct your own signal-conditioning circuits. You can easily construct a low-pass filter,
attenuator or current-to-voltage converter by adding resistors and capacitors onto the boardâs circuit pads.
Applications
ï§ Field wiring for analog and digital I/O channels of PC-LabCard⢠products which
employ the standard 20-pin flat cable connectors or DB37 connectors
(only PCLD-880)
ï§ Signal conditioning circuits can be implemented as illustrated in the following
examples:
a) Straight-through connection (factory setting)
RAn = 0⦠jumper
d) 4 ~ 20 mA to 1 ~ 5 VDC signal converter
RAn = 0 ⦠(short)
RBn = 250 ⦠(0.1% precision resistor)
Cn = none
Pin Assignments
RBn = none
Cn = none
b) 1.6 kHz (3dB) low pass filter
RAn = 10 Kâ¦
RBn = none
Cn = 0.01μF
f3dB =
c) 10 : 1 voltage attenuator
RAn = 9 Kâ¦
RBn = 1 Kâ¦
Cn = none
Attenuation =
(Assume source impedance << 10 Kâ¦)
