The Allen-Bradley 1756-IV16 is a digital sourcing I/O module. This input module has 16 inputs available, with 8 points in a group. Compatible with the ControlLogix 1756 chassis, it requires a removable terminal block housing, or RTB, which can either be the 1756-TBNH or 1756-TBSH before it can be attached to the chassis. Only an input data format is used by this module. The operating voltage range of the 1756-IV16 module is from 10 to 30 Volts DC and it has a 12/24 Volt DC source voltage category. It also has a nominal input voltage of 24 Volts DC. Its total backplane power is 0.61 Watts and maximum inrush current is 250 milliamps. The 1756-IV16 has a maximum input impedance of 3.2 kΩ at 30 Volts DC, a maximum power dissipation of 5.1 Watts at 60 Degrees Celsius, and a thermal dissipation of 18.47 BTU/hour. It also has a continuous isolation voltage of 250 Volts. During an off-state, this module has a maximum voltage of 5 Volts DC and a maximum current of 1.5 milliamps. When it is in an on-state, the 1756-IV16 has a current range of a minimum of 2 milliamps at 10 Volts DC and a maximum of 10 milliamps at 30 Volts DC. The 1756-IV16 module has a screw to backplane input delay time.
