1756-IH16ISOE

The Allen-Bradley 1756-IH16ISOE is a sequence of events module. It has 16 individually isolated inputs available and is compatible with the ControlLogix system. Before it can be connected to the 1756 ControlLogix chassis, it requires either the 1756-TBCH or 1756-TBS6H removable terminal block housing, or RTB. Features of the 1756-IH16ISOE DC sink/source digital input module include per point isolation, FIFO mode operation, and per point timestamping. This module also supports a change of state, although it uses the Enable CST Capture feature. The on-state operating voltage range of the 1756-IH16ISOE is 90 to 140 Volts DC, with a nominal input voltage of 125 Volts DC and this is the same as its sink/source voltage category. Its current draw at 5.1 Volts is 275 milliamps and 2 milliamps at 24 Volts. The module has a total backplane power of 1.3 Watts, thermal dissipation of 17.22 BTU/hour, and a maximum power dissipation of 5.5 Watts at 60 Degrees Celsius. While in off-state, it has a maximum current of 0.3 milliamps and a maximum voltage of 20 Volts. The module's current while in on-state ranges from 1.15 milliamps at 90 Volts DC to 1.85 milliamps at 140 Volts DC. It has an isolation of 250 Volts continuous between inputs. Similar to other modules, the 1756-IH16ISOE has a screw to backplane input delay time.
