Digital output card PA 2000

32 digital outputsISAsafety

The PA-2000 32 digital output ISA card has 32 digital outputs, 24 V, 3 timers and 1 watchdog. The card has galvanic isolation and is protected against fast transient effects (burst), electrostatic discharge and high frequency interference. It is used as an interface to machines or electromagnetic relays, for status monitoring (on/off) of motors, lamps etc. in a severe industrial environment and has numerous safety devices to do so. A CD-ROM containing drivers for Windows and programming examples is included. Features 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 Interrupt triggered through error on the outputs or through timer2 Addressing through DIP switches 16-bit or 8-bit data bus After power-on the outputs are reset to “0” Safety features Optical isolation 1000 V Creeping distance IEC 61010-1 (VDE411-1) Protection against fast transients (burst), overvoltage, electrostatic discharge and high-frequency EMI Maximum output current for 32 output channels: 6 A typ. (2 x 3 A) Self resetting fuse (electronic fuse) Short-circuit current per output 1.5 A typ Output capacitors minimise electromagnetic emissions Fast demagnetization in case of inductive loads External 24 V supply screened through a Protective circuitry
