Functional Description
The PISO-P32A32 has 32 channels
of optically isolated digital input and 32 channels of optically
isolated digital output, arranged into four isolated banks.
Each input channel use a photo-coupler input which allows
either internal isolated power supply or external power selected
by jumper. Each digital output offers a PNP
transistor and integral suppression diode for inductive load.
Isolated input channels 0-15 are designed into group A and
channels 16-31 are designed into group B. Isolated output
channels are designed into group C and Group D. The power
supply of the input port may use the external power or internal
power. The power supply of the output port should use the
external power.
This interface board is easily installed in any PC. The board
interface to field logic signals, eliminating ground-loop
problems and isolating the host computer from damaging voltages.
The PISO-P32A32 has one 37-pin
D-Sub connector and one 40-pin male header. The 40-pin to
DB-37 flat-cable is used to fix with the case. The user can
connect the digital signal through the second D-Sub connector.
Each D-Sub connector contains 16 input channels and 16 output
channels
