PCM-UIO96B

PC/104 MODULE FEATURES Supports 96 digital I/O lines Each line is capable of: Bidirectional operation Input, Output or Output with Read back 12mA Sink Current Generates an interrupt on signal change-of-state: Supports 48 event sense lines Software selectable edge polarity for each line Software enabled interrupt for each line Change-of-state latched for each line Write-protection mask register for each 8-bit port Compatible with industry standard I/O racks Fused +5V logic supply for I/O modules 16-bit PC/104 interface +5 volt only operation Extended temperature range: - 40oC to +85oC Replaces two PCM-UIO48A modules The PCM-UIO96B is a highly versatile PC/104 input/ output module. One important feature of this card is its ability to monitor 48 of the 96 lines for both rising and falling digital edge transitions, latch them and then interrupt the host processor notifying that a change-of-input status has occurred. This is an efficient way of signaling the CPU of real-time events without the burden of polling the digital I/O points. This PC/104 module is also compatible with industry standard isolated I/O signal conditioning modules from Opto-22, Gordos and others. PCM-UIO96B Universal 96-Point I/O with Interruptible Event Sense corresponding output port bit must be cleared. Each output channel is latched and has an open collector driver (with a pull-up resistor) capable of sinking 12mA of current. This allows direct control of up to 96 optoisolated signal condit...
