Technical information

Opto Hardware Reference
requires 25VA power supply, OUT48 requires 50VA power
supply.
The optically isolated inputs are current limited and reverse
polarity protected and provide +/-2500 Volts optical isolation.
Fast TTL buffers, opto isolators and drivers allow a maximum
throughput of 150kHz.
Most of the opto card range have an on board Watchdog
Timer that can be used as a fail safe way to ensure the users
program is running correctly and the PC has not crashed. (Not
available on the DIO16)
The Opto DIO cards are the ideal for high output current
control applications such as driving relays, solenoids, stepper
motors, LED’s or lamps requiring separate logic and load
grounds.
A separate manual "The Interfacing Guide" with a disk full
of worked examples in BASIC, PASCAL, C, Assembler and
FORTRAN ensure that you are up and running with the card
straight away!
