The VME board VME-DPIO32 offers a digital process interface
containing 32 optoisolated inputs or outputs. The board is designed
in 6 U format and covers one slot.
The 32 digital I/O channels are arranged in 8 electrically isolated
groups. Each group of 4 channels has the same reference potential.
The user can allocate input or output operation to each group
separately.
The input voltage range of the channels is between 5 V(DC) and
30 V(DC). Each input channel can generate an interrupt on the VMEbus
on a programmable edge (rising or falling). The inputs are voltageproof between -3 V(DC) and +36 V(DC).
The digital outputs can be operated at voltages between 6 V and
28 V(DC). The continuous outputs current at 24 V supply voltage is
0.3 A. The component LMD18400 is used as output driver.
The driver protective circuit is activated at short-circuit, overtemperature or overvoltage. An error signal of the drivers will be
generated at short-circuit to GND, to VCC, at running without load,
overvoltage or overtemperature of the driver component.
