Product Description

A Digital Input (DI) Module is designed to receive and digitize binary signals from field devices. A binary signal is a simple ON/OFF or TRUE/FALSE state. The module senses the presence or absence of voltage/current from an external device and translates that physical state into a digital value (0 or 1) that the Central Processing Unit (CPU) can read and process.

Typical devices connected to a DI module include:

• Limit Switches and Pushbuttons

• Proximity and Photoelectric Sensors

• Safety Relays and Contactors (Auxiliary Contacts)

• Status Signals from motor starters or process equipment.

Product Parameters

The operational parameters define how the module interacts with the field wiring:

Product Advantages

• High Noise Immunity: Designed with robust filtering and electrical shielding to reliably distinguish true signals from electrical noise (EMI/RFI) in industrial environments.

• Signal Conditioning: Converts varying field signal characteristics into clear, standardized digital data for the PLC CPU.

• High Channel Density: Allows for a large number of inputs to be connected within a compact module footprint, conserving valuable control cabinet space.

• Flexible Configuration: Offers adjustable digital filter times, allowing engineers to optimize the response speed for specific field devices (e.g., fast for proximity sensors, slow for mechanical pushbuttons).

• Integrated Diagnostics: Some modules include advanced diagnostics like monitoring for short circuits, wire breaks, and voltage supply issues, simplifying field troubleshooting.

• Standardized Connection: Uses standardized front connectors or terminal blocks for fast, error-free wiring and quick module replacement.

Important Considerations

• Wiring Type Match: Crucially, ensure that the module’s wiring type (Sinking/Source) matches the type of sensor or field device being connected to avoid damage or incorrect operation.

• Voltage Consistency: Use the correct module variant that matches the field supply voltage (e.g., do not connect a $120,V,AC$ signal to a $24,V,DC$ module).

• Filter Setting: Carefully set the input filter time. A setting that is too fast may cause the module to read spurious noise as a signal; a setting that is too slow may introduce unacceptable delay in the control loop.

• Potential Groups: For modules with grouped isolation, ensure all inputs within a single group share the same ground or common potential to prevent internal cross-talk or damage.

Typical Product Applications

Digital Input Modules are essential across all facets of industrial control:

• Sequential Control: Reading start/stop pushbuttons, emergency stops, and interlock limit switch positions to execute the programmed sequence.

• Monitoring and Status: Sensing the end-of-travel position of actuators, the open/closed status of valves, or the operating status of pumps and motors.

• Safety Systems: Receiving signals from safety light curtains, guard door switches, and other safety devices to execute immediate, safe shutdown procedures.

• Material Handling: Reading sensors to detect the presence, position, and orientation of parts on a conveyor belt or assembly fixture.
