Product Description
Other Models

The 1756-OA8 AC output module has a total backplane power rating of 1.07 Watts. The output delay time (from off to on and on to off) is 9.3 milliseconds at 60 Hertz and 11 milliseconds at 50 Hertz. Eight outputs (4 points each for Group 0 and Group 1) are available on the 1756-OA8 ControlLogix output module. Its States in Fault mode per point and States in Program mode per point can hold the last state (for both the on-state and the off-state). The current rating per point is 2 Amps at 60 degrees Celsius (linear derating) and the surge current rating per point is 20 Amps for 43 milliseconds (repeatable every 2 seconds at 60 degrees Celsius). The maximum power dissipation rating of the 1756-OA8 ControlLogix output module is 5.1 Watts at 60 degrees Celsius while its thermal dissipation is 17.39 BTU per hour. Its slot width is 1 and its minimum load current per point is 10 milliamps. In its off-state, the maximum leakage current of this module is 3 milliamps per point. The 1756-OA8 output module also supports synchronization within 16.7 seconds for scheduled outputs.
