PC/104 I/O card ADDI DATA

Addi-Data presents the new 32-bit digital input/output board PC104-PLUS1500 which has 32 I/O. The PC104-PLUS1500 is equipped with both PCI and ISA connectors on the circuit board. The direct connection to SPS controls is guaranteed because the I/O channels correspond to the industrial standard +24 V for “logic 1”. The input voltage is designed precisely so that the PC104-PLUS1500 switches reliably to „0“ or „1“, even in the case of disturbances. With 0-14 V as “low” and 19-30 V as “high” the ranges are set very high. In order to ensure that the board is interference-free and thus the flawless use in applications, the 32 digital inputs/outputs are isolated up to 1000 V and protected against fast transients, electrostatic discharge and high-frequency EMI.
Two digital inputs are interruptible and thus the main programs are relieved of the standard monitoring and evaluation tasks. In order to avoid undefined states the outputs stay on “status 0” when the PC is started.
The High-Side switch outputs that are available on the PC104-PLUS1500 are designed for inductive loads and PTC resistors, in contrast to the open collector outputs. They work with a nominal voltage of 24 V and an output current of 150 mA and are protected against short-circuit, overtemperature and undervoltage. Additionally, 3 timers or counters are available, whereas Timer1 can work as programmable watchdog for resetting the outputs. A status register that can be read out allows to detect short-circuit or overtemperature.
