Differential I/O Transceiver


See DF-X for newest architecture.

The Differential multi-mode Transceiver module provides 11 individual RS422/RS485 I/O channels, which are programmable for either Input or Output and include extensive diagnostics. Each Differential input channel has a selectable internal resistor (120 ohm or >12 k ohm) across its inputs. Interrupt can be selected, for each channel, to indicate transition on rising edge, transition on falling edge, or both. De-bounce circuits for each channel offer a selectable time delay to eliminate false signals resulting from contact bounce commonly experienced with mechanical relays and switches. All inputs are continually scanned and the data is double buffered for immediate availability.
