The IC693MDL742 is a digital input module from GE Automation's Series 90-30 PLC system. It is used to interface with digital input devices and provide input status information to the PLC system.

Here are some key features of the IC693MDL742 digital input module:

- The module supports a total of 32 discrete input points, allowing for connection to various digital input devices.

- It can accept different input voltage levels, such as 5V DC, 12V DC, or 24V DC, depending on the module variant.

- The IC693MDL742 module offers both sinking (current-sourcing) and sourcing (current-sinking) input types, allowing flexibility in interfacing with different signal configurations.

- It provides short circuit and overvoltage protection for reliable operation.

- The module can be easily integrated into the GE Series 90-30 PLC system using programming software like Proficy Machine Edition.

The IC693MDL742 digital input module is commonly used in industrial automation applications where discrete input signals need to be monitored by the PLC system. It allows the system to receive input status information from devices such as pushbuttons, limit switches, sensors, and other digital input devices.
