The Block I/O family, including the 1791-16A0 has built-in functionalities such as and I/O rack, an adapter, power supply, input and output device. Block I/Os are installed in daisy-chain configuration to a scanner in the network, particularly a controller. Input and outputs are asynchronously scanned and transferred to and from the block I/O and the controller.
The 1769-16A0 supports integration of proximity switches, limit switches, selector switches, float switches, pushbutton switches, auxilliary contacts and other discrete operating devices.
The 1769-16A0 is compatible for use with 1771 series output modules provided that the off-state leakage current of the module is less than the minimum OFF-state current of the Block I/O. Additionally, the minimum ON-state voltage of the bock I/O must be higher that the supply voltage, less the on-state voltage drop across the 1771 output module. A number of modules that meet the compatibility requirement includes the 1771-OAN, 1771-OD16, 1771-ODD, 1771-ODZ and some other modules.
