This module is rack mountable and occupies a slots in the 1771 Input Output chassis. The 1771-OBNK operates within a voltage range of 10 to 30 Volts direct current and has a maximum power and thermal dissipation of 13.7 Watts and 46.7BTU per hour respectively. The minimum power and thermal dissipation rating of the 1771-OBNK is 1.7 Watts and 5.7 BTU per hour respectively.

The 1771-OBNK DC high-Tru conformally coated output module operates optimally at a temperature ranging between 0 and 60 degrees Celsius, and a non-condensing relative humidity of between 5 and 95 percent. The 1771OBNK has a storage temperature rating of between -40 and +85 degrees Celsius. The conformal coating helps the module withstand harsh environmental conditions in an industrial setting. For wiring, the module uses a 14 gauge maximum stranded wire that has a maximum insulation of 3/64 inch.

When switched off, the 1771-OBNK module leaks a current of 1 milliampere at a temperature of 55 degrees Celsius. Also, the module has a backplane current rating of 330 mA at 5 Volts DC. The 1771-OBNK module has a 2 A, 5 A, and 20 A per output, output group, and module maximum surge current repeated each 2 seconds for 10 milliseconds. The maximum output signal delay for the 1771-OBNK stands at 2 milliseconds for the on-off operation while the off-on has a 0.1 milliseconds delay. When installing the 1771-OBNK module into the I/O chassis, switch off the power supply to the I/O chassis to avoid injury to personnel and the 1771-OBNK module.
