This module also measures 118 x 87 x 35 millimeters in dimensions, including its mounting tabs which are 138 mm and weigh approximately 280 grams or 0.61 pounds. The 1769-SDN has a maximum Bus Current Draw and its maximum heat dissipation is 440 mA at 5 Volts DC (2.2 Watts) and 3.8 Watts respectively.

The 1769-SDN should not be installed anywhere that contains volatile or corrosive gas, vapors, or dust in the ambient atmosphere. The 1769-SDN has an operating temperature of 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit and it should not be stored anywhere in a corrosive atmosphere. The maximum cable distance between this module and the connected PowerFlex 4-Class drives is 10 meters. The maximum cable length must be 500 meters at 125K baud and 100 meters at 500K baud. The 1769-SDN cannot be located more than 4 modules away from the power supply, thus, it has a Power Supply Distance Rating of 4. Its DeviceNet power requirements are N.E.C. Class 2 90 mA at 11 Volts DC, 110 mA at 25 Volts DC, and 200 mA for 1.5 milliseconds. The 1769-SDN is able to read inputs and write outputs to and from slave devices, communicate with peer devices, and load programs to a 1764-LRP-based controller across a given DeviceNet network.
