The GE Fanuc IC693MDL632 is a 125-volt DC Positive/Negative Logic Input module designed for use with the Series 90-30 PLC. This module features eight input points organized into two isolated groups, each with its own dedicated common. The commons are electrically isolated within the module, allowing for flexible configuration. To operate field devices, power must be supplied to the input devices, which can include various types such as electronic proximity switches, pushbuttons, and limit switches. The IC693MDL632 supports both positive and negative logic operation, enabling it to sink current to the user common for positive logic or source current from the input devices to the user common for negative logic. The module is equipped with an LED block featuring two horizontal rows of indicators, with the top row utilized to display the on/off status of each input point. Additionally, a hinged door provides access to a removable insert that contains circuit wiring information on its interior and allows for circuit identification details to be recorded on its exterior. The outer-left edge of the insert is color-coded red, indicating that this is a high-voltage module. The technical specifications include a rated voltage of 125 volts DC, eight inputs with an input current of 4.5 mA, and 1500 volts of isolation between the field side and logic side. DC power is required for operation.
