The CC‑TD0R01 is a discrete output relay module intended for industrial digital control systems. Unlike solid-state digital outputs, this module uses relay switching, making it suitable for driving higher‑power loads, AC devices, or loads requiring true isolation. It is often employed in systems where reliability, isolation, and switching robustness are critical.
It integrates into modular I/O racks or control cabinets, delivering dependable relay outputs under automation control. Its design emphasizes durability, fault isolation, and compatibility with wide industrial environments.

The CC‑TD0R01 module receives digital command signals (e.g. from a controller or I/O bus) and actuates internal relay contacts to switch external devices. Each of its 8 channels provides a physical relay closure, isolating the module electronics from the load side — ideal for AC / DC loads, larger motors, solenoids, or signals requiring full galvanic separation.
The module includes built-in coil suppression, overcurrent protection, and diagnostic detection (such as stuck contacts or coil failure). Its relay design ensures low leakage, strong isolation, and compatibility with diverse load types, making it suitable for industrial control applications where robustness is paramount.
