Functions of the board

PA 1500

9.2

General description

The board

PA 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 are available:

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).

The base address is set with a 10-pin block of DIP switches and jumper J2.
Decoding occurs on the 64 KB I/O address range of the PC.
The board requires 8 I/O addresses within the I/O address range of the PC.

Available interrupt lines:
IRQ3, IRQ5 on XT
IRQ10, IRQ11, IRQ12, IRQ14, IRQ15 on AT

The 16-bit data bus can be switched over to 8-bit data bus.

EMC: design in accordance with CE regulations.

WARNING!
Do not operate

the board simultaneously in several modes. Otherwise you

may damage the board, PC and/or the peripheral.

Make sure

to set only the jumpers required for the respective functions.
