Opto-isolated Process I/Os
VME-DPIO32 contains 32 opto-isolated digital process I/O channels.
It includes all necessary components on a VMEbus 6U board and needs one slot.
Wide Voltage Ranges
The 32 digital I/O channels are programmable in 8 groups of 4
channels as inputs or outputs. The 8 groups are electrically isolated from each
other. The input channels accept an input voltage range of 5 VDC to 30 VDC.
Each input channel can generate an interrupt on the VMEbus and that is
programmable to rising or to falling edge. The inputs are overvoltage protected
between -3 VDC and +35 VDC. The digital output channels accept an operating voltage
range of 6 VDC to 24 VDC with a rated current of 0.3 A.
Output Protection and Error Signals
The output drivers are the components LMD18400. The protection
circuit of the driver is activated by short-circuit, over temperature and
overvoltage. The drivers generate an error signal in the following conditions:
no load, short-circuit to GND, to VCC , overvoltage or over temperature of the
driver module.
PWM
In addition to the bit programmable operating mode of the outputs,
it is possible to use the single output channels via the pulse processor
components HD63143 for pulse-width modulation (PWM). A total of 2 x 24
programmable 16-bit registers for switching period and resolution are
available. The minimum pulse width amounts to 10
:s.
You can synchronize the outputs.
Counter Inputs
There are up to 20 digital inputs to use as counter inputs, with four
connected in parallel to CIO8536 and to HD64143. The maximum counter frequency
for these four inputs is 3 MHz (CIO 8536). Depending on the operating mode, the
counters of the HD63143 can process frequencies of up to 100 kHz or up to 1
MHz. For the counter inputs, different operating modes are possible: Event
counter, pulse-width measurement, frequency measurement, free running with
interrupt, incremental encoder inputs etc.
Display and Simulation
The actual I/O status and error status of each I/O channel is
displayed by a two-colored LED on the front panel of the VMEDPIO32. Additionally,
there are test sockets for each channel located on the front panel for
stimulation of the input channels or for disable of the output driver error
signal.
Software Support
Driver software for the VME-DPIO32 is available for all popular
operating systems.
