About 1794-OB16P

The Allen-Bradley 1794-OB16P is a FLEX 24 Volts DC Series A digital I/O module. It has 16 source outputs that are non-isolated and protected and has been conformally coated, with 0.5 Amps for each output. It can handle overloads, high temperatures, and shorts because it features self-protection. Once the problem is solved, the faulted output will return automatically; however, feedback to the processor will not. This module can communicate on ControlNet, DeviceNet, PROFIBUS, and EtherNet/IP networks and comes with an RS-232 communication port. The 1794-OB16P module uses screw clamp terminations and it can only be mounted on a DIN rail and only use the following terminal base units: the 1794-TB3, 1794-TB3K, 1794-TB2, 1794-TBN, 1794-TBNK, 1794-TB3S, and the 1794-TB3SK.

It has an external DC supply voltage range of 10 to 31.2 Volts DC, with the 5% AC ripple included, and an external DC supply current range of 25 to 75 mA. The 1794-OB16P’s on-state voltage range is also 10 to 31.2 Volts DC. Its on-state output voltage drop is 0.5 Volts DC. The minimum current on-state output is 1 mA per channel and the maximum is 500 mA per channel or 8 Amps per module. This module also has a leakage current of 0.5 mA for off-state output and a maximum output surge current of 1.5 Amps for 50 milliseconds that is repeatable every 2 seconds. Note that this module does not have any isolation between the individual channels.

The 1794-OB16P’s output delay is 0.5 milliseconds in the OFF to ON state and 1 milliseconds in the ON to OFF state. The maximum power dissipation is 5 W at 31.2 Volts DC, the thermal dissipation is 17 BTU/hour at 31.2 Volts DC, and the maximum Flexbus current is 60 mA. The 1794-OB16P module has an operating temperature of 0 to 55 degrees Celsius and a storage temperature of -40 to 85 degrees Celsius and comes with a non-condensing relative humidity of 5 to 95%. It also has an operating vibration of 30g and a non-operating vibration of 50g. Its vibration is 5 g at 10 to 500 Hertz.
