Description

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, +12V and +24V 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 +5V nominal output range. The output stage of the Opto-coupler can drive up to 8mA with a maximum voltage of 30V. 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.
