General description
The PCE-1601 board is used to conditioning TTL/HC signals of the TEDIA DAQ
PC card digital ports to external equipments with technological signal levels and
contains eight input and eight output channels.
As standard, the input channels are designed for DC signals up to 32 V both
polarities, but as an option filter capacitors can be added in order to add
compatibility with AC signals with a frequency of 50 Hz.
The output channels are solved by individually isolated switching relays.
All channels work as non-inverting; the presence of the input voltage is represented
by the "H" level and the "H" level at the PC card output activates the signal switch.
General instructions for use
The PCE-1601 may be used only according to the manufacturer's recommendations
given in this manual or other general standards and only such a way, that its failure
caused by any reason will not be dangerous to any person or property.
Installation
The PCE-1601 is designed to be placed into a free slot for expansion cards, the
length of the ribbon cables requires a position adjacent to the control PC card.
The board can be used in an environment with operating temperature -10~60 °C and
relative humidity up to 90%, noncondensing and normal levels of pollution.
