DM6888HR
Add to Info-List

PC/104 64-Channel High Density Isolated Digital I/O

The DM6888HR dataModule combines 48 Opto-isolated digital inputs and 16 Opto-isolated digital outputs on one board. The inputs are factory configured for a +5 V, +12 V, and +24 V input ranges (customized input range available upon request). A schottky reverse voltage protection diode improves system reliability.

The outputs of the DM6888HR have an open collector configuration. A pull-up resistor is factory installed for a +5 V nominal output range. The output stage of the Opto-coupler can drive up to 8 mA with a maximum voltage of 30 V.

The outputs of the DM6888HR are inactive after reset and will maintain their state even if the system is reset. This will prevent uncontrolled output operation in cases of system operation failure.
