【英文介绍】

Allen-Bradley's 1756-OB16IS ControLogix output module is an output module located in the slot of the 1756 chassis, which has 16 separate feed/pull current outputs, eight of which are being scheduled. It has a 2A (DC-13SQ) contact rating and 0-30V operating voltage. The signal delay time from OFF to ON is 1ms, the signal delay time from ON to OFF is 2ms, and the signal delay time is 350mA at 5.1V DC and 2.5mA at 24V DC backplane, for a total backplane power consumption of 1.8W. The module has a maximum power consumption of 3.6W at 60 °C and a heat dissipation of 12.28 BTU/hr. The maximum voltage loss in the ON state is 1.2V DC, the current is 2A, and the leakage current per point is 0.5mA. The nominal current at each point is 1A/2A at 30/60 0C, the maximum current on the module is 8A/4A at 30/60 0C, the module has 4A surge current at 10ms, each output point can be repeated every 2 seconds, and the minimum current load at each point is 1mA.

It has eight scheduled outputs synchronized within 16.7 seconds of coordinated System Time (CST) and has a hold last state, on or OFF failure state, with the default state being OFF. It has 250V isolation between output to backplane and output to output, with basic type insulation, and was routinely tested for 2 seconds at 1350V AC. It is designated with T4A (North America) and IEC T4 temperature codes and comes with an open housing. It has a maximum ambient temperature of 60 °C (140 °F) and has been tested to operate within the specified performance standards with an operating vibration of 2G and a shock of 30G.
