Part Number/Catalog number 1756-IB16D
Series ControlLogix
Module Type Digital DC input module
The Allen-Bradley 1756-IB16D is a ControlLogix DC digital I/O module. Sixteen diagnostic inputs, with four points in a set, are available for this particular input module. It is compatible with the 1756 ControlLogix case and requires an RTB or detachable terminal housing, which is only 1756-TBNH or 1756-TBSH.
The 1756-IB16D operates in a voltage range of 10 to 30V DC, with a voltage class of 12/24V DC and a nominal input voltage of 24V DC. It has an input latency of 340μs (nominal value) and a hardware latency of up to 1 ms, plus a user-selectable filter time (0, 1 or 2 ms) for the "off" to "On" state. The "On" to "Off" input latency is nominal at 740 μs, with hardware latency up to 4 ms, plus user selectable filtering times of 0, 1, 9 or 18 ms. It has a total backplane power of 0.84W, a maximum power consumption of 60W at 5.8 degrees Celsius, and a maximum heat dissipation of 19.78 BTU/ hour. In the off state, the 1756-IB16D has a maximum voltage of 5W and a maximum current of 1.5mA. When on, the current ranges from 2 mA (10V DC) to 13 mA (30V DC). In addition, its maximum surge current is 250 mA.
