Allen-Bradley 1756-IN16 AC digital input module

The Allen-Bradley 1756-IN16 is an AC digital input module with 16 inputs, having 8 points per group. It can be used with the 1756 ControlLogix chassis but it needs a removable terminal housing, or RTB, before it can be connected to the chassis. The 20-pin RTB compatible with the 1756-IN16 module are the 1756-TBSH and the 1756-TBNH. You can configure a change of state and input filter times with this particular module. The module has an operating voltage range of 10 to 30 Volts AC and 47 to 63 Hertz and a voltage category and nominal input voltage of 24 Volts AC 50/60 Hertz. It has a total backplane power of 0.56 Watts and a maximum inrush current of 250 milliamps. The module's current draw at 5.1 Volts is 100 milliamps and at 24 Volts, it is 2 milliamps. The power dissipation of the 1756-IN16 module is a maximum of 5.1 Watts at 60 Degrees Celsius and its thermal dissipation is 17.39 BTU/hour. When in an off-state, the module's maximum voltage is 5 Volts, while the maximum current is 2.75 milliamps. The current ranges from 5 milliamps at 10 Volts AC, 60 Hertz to 1.2 milliamps at 30 Volts AC, 60 Hertz during its on-state.
