- Status Display: Each channel has a green LED status display, indicating its operational status.
- Interrupts and Diagnostics: The module does not support interrupts or diagnostic functions.
- Encoder Selection Data: The module does not support encoder selection data.
- Input Voltage: The input voltage for the module is 24 V DC, with a reference potential of L+ (positive).
- Input Current: The input current for a "1" signal is typically 7 mA, and the input delay for both "0" to "1" and "1" to "0" transitions is 1.2 ms to 4.8 ms.
- Connection: The module connects using a 20-pin front connector and supports wiring of signal transmitters.
- Dimensions and Weight: The module measures 40 mm x 125 mm x 117 mm and weighs approximately 260 grams.
- Module-Specific Data: The module supports isochronous mode and has a maximum cable length of 600 meters for unshielded and 1000 meters for shielded cables.
- Special Features: The module is designed for fast operation and supports redundant load control, making it suitable for applications that require high-speed processing and reliable load management.
