New version of the APCIe-1500 with 32 digital I/O
Rheinmuenster, 18th june 2015 – The new digital I/O board APCIe-1500-FC for PCI-Express has 3 fast counter inputs, that allow a maximum input frequency of 140 kHz, in addition to the 16 filtered inputs and outputs of the standard version APCIe-1500. 14 inputs are interruptible.
The board is developed for I/O control in the industrial field and thus comes with numerous protective circuits such as optical isolation of 1000 V, filters, reverse voltage protection etc. For testing and setting up the board functions, a monitoring program is included. The following drivers are available: 64- and 32-bit drivers for Windows 8/7/XP as well as Linux drivers. For real-time applications with Windows, RTX and RTX64 extensions are available.
In compliance with the industrial standard, “logic 1” corresponds to an input voltage of > 19 V, “logic 0” corresponds to an input voltage of < 14 V.
An initialisation of the inputs is not necessary as the digital information can be read directly at “power on”. The outputs work with the positive logic, this means the output is set through software to “logic 1”. The output current is 500 mA per channel. To guarantee a safe starting of the equipment, the outputs are set to “0” after reset. In case of voltage drop the outputs are deactivated. The readable status register allows to detect short circuits, over-temperature, voltage drop or watchdog. The board has an interrupt line, defined through the BIOS. Several interrupt sources such as interruptible inputs, timer, watchdog, counter overflow etc. can be read. The information about the source is available in the interrupt routine. For the 3 timers, a time base independent from the PC cycle can be defined, for example to synchronise operations. Timer 0 can be programmed as watchdog for resetting the outputs to “0”. The time units µs, ms and s time can be set for the watchdog.
