Description
GE IC693MDL645D 24VDC Digital Input Module
Product Dimensions：
The GE Fanuc IC693MDL645D (now managed under Emerson Automation Solutions) is a 24 V DC Positive/Negative Logic Input Module designed for the Series 90-30 Programmable Logic Controller (PLC) system. It provides 16 discrete input channels to interface between the PLC and external field devices.
Product Detailed Description
The IC693MDL645D is a modular input card that occupies a single slot on a Series 90-30 PLC baseplate. It is a “Grouped” type module, meaning the 16 input channels are split into distinct isolated groups, allowing the module to accept signals from different power sources or configurations. The “Positive/Negative” capability indicates that it can be wired in either a Sinking or Sourcing configuration, providing excellent wiring flexibility.
Technical Parameters
| Feature | Specification |
| Model Number | IC693MDL645D (Revision D) |
| PLC Series | Series 90-30 |
| Number of Inputs | 16 Channels |
| Rated Voltage | 24 V DC |
| Input Voltage Range | 0 to +30 V DC |
| Input Current | 7 mA (typical) at 24 V DC |
| On-State Voltage | 11.5 to 30 V DC |
| Off-State Voltage | 0 to 5 V DC |
| Input Filter Delay | 7 ms (typical) |
| Isolation | 1500 V between field side and logic side |
| Power Consumption | 80 mA from the +5V bus on the backplane |
Product Advantages
- Sinking/Sourcing Flexibility: Supports both positive and negative logic, allowing compatibility with a wide range of field sensors (NPN or PNP).
- Optical Isolation: Features robust optocouplers that isolate the sensitive internal PLC logic circuitry from high-voltage transients on the field side.
- Status Indicators: Includes a top-mounted LED block showing the real-time ON/OFF status of each of the 16 individual points, simplifying troubleshooting.
- Hot-Swappable Terminal Block: The field wiring terminal block can be detached from the module, allowing for quick hardware replacement without disconnecting individual field wires.
Important Considerations & Precautions
- Input Delay: The module has a hardware filter delay of approximately 7 ms. It is not suitable for high-speed counting or capturing ultra-fast pulses; use a High-Speed Counter (HSC) module for those applications.
- Backplane Power Budgets: The module draws 80 mA from the 5V PLC backplane power supply. Ensure the total current draw of all modules does not exceed the power supply rating.
- Proximity to Interference: Route 24V DC input signaling cables away from high-voltage AC motor lines to prevent electromagnetic noise from causing false input triggers.
Product Applications
The IC693MDL645D is a standard digital input card used to monitor binary states in industrial machinery:
- Manufacturing Lines: Monitoring the state of limit switches, proximity sensors, and photoelectric eyes.
- Operator Panels: Reading pushbuttons, selector switches, and emergency stop statuses.
- Material Handling: Detecting the presence or absence of packages on conveyor lines.
- Process Automation: Interfacing with basic auxiliary contacts on motor starters, circuit breakers, and valve limit switches.
