Technical description
8.1.2

Description

The board APCI-/CPCI-1500 is intended for parallel input/output for digital
signals in 24 V industrial environment.
The peripheral and the system have a simultaneous optical isolation.
The board offers:
- 16 digital inputs: 14 are interruptible.
- 3 counters (or timers): programmable by software
- 1 timer: can be used as a watchdog for the outputs.
- 16 digital outputs:
The base address and the interrupt lines are automatically set through the BIOS.
EMC: design in accordance with CE regulations.

Digital input s

WARNING!
Do not operate the board simultaneously in several modes.
Otherwise you may damage the board, PC and/or the peripheral.
The board APCI-/CPCI-1500 supplies 16 optically isolated inputs.
The inputs comply with the 24 V industry standard (IEC1131-2):
CPCI-1500:
- logic "1" corresponds to an input voltage > 17 V
- logic "0" corresponds to an input voltage < 15 V.
APCI-1500:
- logic "1" corresponds to an input voltage > 19 V
- logic "0" corresponds to an input voltage < 17 V.
All the inputs have a common current ground:
0V Ext. (inputs), pin 10 of the 37-pin SUB-D male connector.
The current input is at 6 mA with a nominal voltage of 24 V.

- short-circuit current,
- protection against overtemperature,
- small ON-resistor,
- wide supply voltage range,
- the outputs are switched off if the voltage drops below the limit value (5 V).
