PA 2000 Digital Output Board

Quick Overview

The PA2000 is a digital output board with 32 digital outputs. Each output channel has a voltage range of 10 to 36V with an output current of 500mA. 3 16 bit timers and 1 programmable watchdog and 2 output channels for generating square wave output signals. All output channels can be triggered independently with DIP switch addressing. The board is optically isolated up to 1000V and protected against overvoltage. The PA2000 is suitable for applications such as industrial digital output control, monitoring of motors & lights, machine interfacing, signal switching, etc. A CD-ROM with software drivers and programming examples is supplied with the board.

Features

32 digital outputs, 24 V, isolated
Output current: 500 mA
Voltage range: 10 to 36 V
Diagnostic reports, readable through status register in case of short-circuit, overtemperature, voltage drop or watchdog
3 x 16-bit timer (82C54): Timer as programmable watchdog for the reset of the outputs to “0”; Function release through software; Control of 2 output channels for generating square-wave signals
