1769 Compact I/O Modules Specifications
External resistors are required if they are not internal to the encoder. The pull-up resistor (R) value depends on the power
supply value. To calculate the maximum resistor value, the following formula:
where:
• R = maximum pull-up resistor value
• VDC = power supply voltage
• Vmin = 2.6V DC
• min = 6.8 mA
The minimum resistor (R) value depends on the current sinking capability of the encoder.
