OVERVIEW
The LPM/MCM-OPTO48 is a highly versatile 48 channel, optically isolated and debounced STD Bus digital input card for industrial applications. Each input line is isolated from the others and from the bus interface circuits to provide a barrier between the control system and harsh industrial environments.
One important feature of this card is its ability to debounce then monitor both rising and falling edge transitions of a signal, latch it and then interrupt the processor to signal that a change of status has occurred on any input line.
