PCD-8104, PCD-8105, PCD-8106

The PCD-8104/05/06 card is an additional type of multifunctional DAQ PCI card series offering isolated digital inputs and bidirectional digital ports.

The card provides 24 isolated digital inputs and three 8-bit bidirectional digital ports, software configurable as input or output. Moreover, the power-up configuration of DIO ports can be easily modified by the software utility and stored into onboard EEPROM memory.

The card also includes IRQ logic with interrupt sources derived not only from the internal timer, but from rising or falling edge of each digital port signal (i.e. 96 individually programmable interrupt sources).

The PCD-810x card is based on a FPGA unified core providing implementation of PCI Express bus and all peripheral circuitry, e.g. solution that gives maximum control and supervision over full functionality. High concentration of control algorithms within FPGA allows to add or modify functions without redesign the board.

All DAQ PCI Express cards are equipped CardID - two segment DIP switch that allows to recognise up to 4 cards (especially when installing multiple cards of the same type).

PCD-8104, PCD-8105 and PCD-8106 diferences

PCD-8104 - digital inputs intended for TTL/HC signals
PCD-8105 - digital inputs intended for driving by "PNP" outputs with 24V signal level
PCD-8106 - digital inputs intended for driving by "NPN" outputs with 24V signal level

All other features including isolation of digital input block are identical.

Standard and low-profile version

The cards are supplied in two versions - standard as PCD-810x and as PCD-810x/LP. Except for the different I/O connectors (see the following paragraphs), all other features of both versions are identical.

In the case of a standard version, isolated digital inputs are accessible via the D-Sub 25 connector, first digital port via the D-Sub 9 connector then (PCE-8019 cable); both of them are located on the card mounting bracket. Next two digital ports are accessible via the PCE-16xx series adaptor (not included), using the card mounting bracket with two D-Sub 25 or D-Sub 9 connectors.

In the case of a low-profile version, isolated digital inputs are accessible via the D-Sub 25 connector located on the card mounting bracket. All three digital ports are accessible via the PCE-8025/LP adaptor (not included), using the card mounting bracket with one D-Sub 25.

Delivery details

The product packet includes the card and InfoCD with drivers and user manual.
