Part Number 1794-OB32P designed by Allen-Bradley belongs to the input / output modules product line. This I/O module is a flex input / output digital module having 2 groups of 16 outputs, hence, a total of 32 output channels. Each of these has its separate voltage supply while each of these has an output voltage of 24 volts DC. That is why they are used for electronic and electrical devices requiring a 24 volts DC supply for their proper operation such as electrical loads, indicating devices, and sounding devices. Part numbers 1794-TB32S and 1794-TB32 are the only terminal base units with which this flex I/O module is compatible. The point channels have a total output current of 14 amperes, out of which 6 amperes are given by the 0-15 channels and 8 amperes are given by channels 16-31. The maximum and minimum output amperage per channel is 500 milliamperes and 1 milliampere, respectively. These point sources are electronically protected in case of temperature overload and their condition is indicated by 32 yellow status indicators. Moreover, these channels are not individually isolated.

Part Number 1794-OB32P flex I/O module comes without a conformal coating and has an operational temperature rating of 0 ºC – 55 ºC and is unable to withstand high temperatures. This module features a maximum output leakage current of 0.5 milliamperes, a maximum output surges current of 2 amperes for 50 milliseconds, a maximum output delay time from off to on of 0.5 milliseconds, a maximum output delay time from on to off of 1 millisecond, maximum power and thermal dissipation of 5.5 watts and 18.1 British Thermal Units per Hour (BTU/hr), respectively, and operating at max 31.2 volts DC supply. This module operates at an external DC voltage supply range of 10 to 31.2 volts DC with a 5% AC ripple and an external DC supply of 103 to 273 milliamperes. 1794-OB32P is DIN mounted.
