The 1756-OA16 also supports 2 removable terminal blocks, the 1756-TBSH and the 1756-TBNH. The 1756-OA16 module can be set to different operating or non-operating states, including the on-state, off-state, and last state (a reset function that resets a module that was suddenly powered down to the last operating state that it was in). The maximum voltage drop in the on-state is 1.5 Volts at 0.5 Amps and 5.7 Volts at a load current of less than 50 mA. On the other hand, the maximum leakage current in the off-state is 3 mA per point. The 1756-OA16 also features an output delay time for the off to on state which is 9.3 milliseconds at 60 Hertz, and one for the on to off state is 11 milliseconds at 50 Hertz. To alert the users if the point or group fuse is blown, the 1756-OA16 module will indicate this with the fault word tag name FuseBlown. Another fault word tag name is FieldPwrLoss which indicates a loss of field power to the modules output points. The 1756-OA16 can operate in a temperature range of 32 to140 degrees Fahrenheit and it can be stored or transported at a temperature range of -40 to 185 degrees Fahrenheit. It can operate and be stored in an environment with a relative humidity range of 5 to 95%, non-condensing.
