*Actual output is equal to power supply input minus 0.7V DC
Digital Inputs #0-2
The digital input lines are CMOS/TTL compatible and can handle voltages from
Digital Outputs #0-2
The digital output lines are CMOS/TTL compatible. A digital output that is set to a “0” (LOW) will output a voltage from 0 to 0.6V DC. A digital output that is set to a “1” (HIGH) will output a voltage from 4.3V DC to 5.0V DC. Refer to Chapter 1, Specifications, for more information. Unused digital output lines should be left open.
