Part number 1794-IV16 is a unit designed to function as an input module. This input module was created by Allen-Bradley and has FLEX I/O. The input system for the module is discrete and the nominal source input for this unit for the ON-state is 24 volts direct current (DC). Additionally, the voltage range for the ON-state is 10 volts to 31.2 volts, and the voltage range for OFF-state is 0 volts to 5 volts. It is an open-style module with a DIN mount and an IP rating of IP20.
The 1794-IV16 is a module that was manufactured by Allen-Bradley / Rockwell Automation and is designed to be an input module. The module belongs to a 1794 catalog series of FLEX I/O digital sourcing input and sinking output modules. As described by the series name, the input module has Flex I/O, which is defined as a distributed Input/Output, or I/O, system that provides the capability to connect to several different types of networks, which include ControlNet, DeviceNet, and Ethernet/IP. The inputs are discrete, and the number of inputs is 16, which are non-isolated and sourcing. As inputs are discrete, there are two input states, which are the ON-State and the OFF state. The module is made to be an open style module and it has a standard type of DIN mount. This device has an IP rating of IP20.
Additionally, the ON state and the OFF state have voltage and current ratings. For the ON-State, the voltage range for the rating is 10 volts direct current (DC) minimum to 31.2 volts direct current (DC) maximum. Nominally, the voltage
should be 24 volts direct current (DC). The current rating for the ON-state is 2 milliamperes (mA) minimum to 11 milliamperes (mA) maximum and nominally, the current should be 8 milliamperes (mA) at 24 volts direct current (DC). For the OFF-State, the voltage should be a maximum of 5 volts direct current (DC) while the current should be a minimum of 1.5 milliamperes (mA). The maximum input impedance is 4.7 kilo-ohms. Additionally, at 31.2 volts direct current (DC), the maximum power dissipation is 5.7 watts (W).
