Allen Bradley 1756-IB16ISOE ControlLogix Digital I/O Module.

The Allen Bradley 1756-IB16ISOE is a ControlLogix Digital I/O Module. This digital input module has 16 inputs available which are all individually isolated. This module requires a removable terminal block housing, or RTB, of either 1756-TBCH or 1756-TBS6H.

The 1756-IB16ISOE is known as a Sequence of Events module, where event times are reported in either UTC (universal time coordinated) or CST (coordinated system time) format. The sequence of events modules timestamps information in under a millisecond. This feature will register a time in relation to a change in the input data. All of this occurs on a per-point basis. It also provides basic ON/OFF detection, a feature common to other ControlLogix modules.

The operating voltage range of this module is from 10 to 55V DC with a nominal input voltage of 24V DC and a voltage category of 24/48V DC sink/source. It has a current draw of 320 mA at 5.1V and 2mA at 24V, with a total backplane power of 1.7W. The thermal dissipation of this module is 17.22 BTU/hour while power dissipation is 5.5 W at 60 Degrees Celsius. The on-state current for this module varies from 2.0 mA at 9V DC to 5.1 mA at 48 to 55V DC, although the nominal current is 4.5 mA at 4 to 31V DC. The maximum off-state current is 1.5 mA and the maximum voltage is 5V.
