The GE-Emerson IC692MDR541 Series 90-20 DC Input/Relay Output Power Supply provides input circuits designed to have positive or negative logic characteristics. To connect the inputs as positive logic circuits, the input switching device is connected between the positive power bus and the module input. The negative bus is connected to the input circuit common. To connect the inputs as negative logic circuits, the input switching device is connected between the negative power bus and the module input. The positive bus is connected to the input circuit common. Current into an input point results in a logic 1 in the input status table (%I).
Input characteristics are compatible with a wide range of input devices, such as: pushbuttons, limit switches, and electronic proximity switches.
The 2 Amp relay output circuits provide 11 normally-open relay circuits for controlling output loads provided by the user. The output switching capacity of each of these circuits is 2 Amps. The output points are arranged in three groups; one with three outputs and two with four outputs. Each group has a common power output terminal. The relay outputs can control a wide range of user-supplied load devices, such as: motor starters, solenoids, and indicators. Power for the internal relay circuits is provided by the +5VDC internal supply. The user must supply the AC or DC power to operate field devices. Each common has a 10 Amp replaceable fuse.
