48-channel DIO Module Main Feature
48 digital I/O lines
Channels simulate 8255 PPI mode 0
Buffered circuits for higher driving capacity than the 8255
Bit 0 of port C can generate an interrupt to IRQ 2 to 7
Interrupt triggering rising/falling edge
Output status readback
Pin-compatible with Opto-22 I/O module racks
Transfer rate: 300 Kb/sec typical, 400 Kb/sec Maximum
Digital output: Logic level 0: 0.5V max @ 24mA sink
Digital input: Logic level 0: 0.8V max Logic level 1: 2.0V min
Power requirement: 90mA @ +5V(±5%)
