Part Number/Catalog number 1756 -IB16ISOE year
Series ControlLogix
Module Type Digital DC isolated input event sequence
Allen-Bradley 1756-IB16ISOE is a ControlLogix digital I/O module.
The digital input module has 16 available inputs, all of which are individually isolated. The module requires a removable terminal housing or RTB of 1756-TBCH or 1756-TBS6H.
1756-IB16ISOE is known as the Event Sequence module, where event times are reported in UTC (Coordinated Universal Time) or CST (Coordinated System Time) format. The event sequence module adds a timestamp to the message within a millisecond. This feature records the time associated with changes to the input data. All of this happens on a point by point basis. It also provides basic on/off detection, which is common to other ControlLogix modules.
The module has an operating voltage range of 10 to 55V DC, a nominal input voltage of 24V DC, and a voltage class of 24/48V DC input/pull current. It has a current consumption of 320 mA at 5.1V and 2mA at 24V, with a total backplane power of 1.7W. The module has a heat dissipation of 17.22 BTU/ hour, while the power consumption is 60 W at 5.5 degrees Celsius. The conduction current of the module varies from 2.0 mA for 9V DC to 5.1 mA for 48-55V DC, but the nominal current is 4.5 mA (4V to 31V DC). The maximum turn-off current is 1.5mA and the maximum voltage is 5V.
