Thank You For Buying the
Optically Isolated
Input Output Interface!
We proudly present a range of optically isolated digital
input output cards.
OPTO DIO48 provides 24 high voltage, high current
outputs lines and 24 input lines all with +/-2500 Volts optical
isolation.
OPTO DIO16 provides 8 high voltage, high current outputs
lines and 8 input lines all with +/-2500 Volts optical isolation.
OPTO OUT48 gives the user with 48 high voltage, high
current outputs lines with +/-2500 Volts optical isolation.
OPTO OUT24 gives the user with 24 high voltage, high
current outputs lines with +/-2500 Volts optical isolation.
OPTO IN24 gives the user with 24 input lines with +/-2500
Volts optical isolation.
The optically isolated outputs are high voltage, high current
outputs lines, with +/-2500 Volts optical isolation. Fast TTL
buffers, opto isolators and drivers allow a maximum throughput
of 150kHz. The cards may be fitted with source drivers or with
sink drivers. The on chip current limiting resistors and output
transient suppression diodes have been augmented by on board
higher duty suppression diodes and pull down resistors so
ensuring long term use in an industrial environment.
Cards with these outputs require an external, user supplied,
power input to supply the opto isolators and the i/o drivers. On
board regulation allows the use of unregulated supplies in the
range 17.5-35 Volts. A minimum of 8VA current capability per
8 line source output package is needed. ie OUT24, DIO48
