Meet the ALLNET ALL3003 Schaltausgang — a compact, optocoupler-based switch output designed for reliable, isolated control in automation and electronics projects. This single-channel device offers a potential-free contact, making it easy to interface different voltage domains without shared references.

Key Features & Design

• Channel: 1 optocoupler-based switch output
• Isolation: potential-free (galvanic isolation between control and load)
• Design: compact, easy-to-integrate module
• Interface: straightforward input drive for control circuits
• Applications: automation, PLC interfacing, microcontroller projects

Performance & Benefits

The optocoupler provides electrical separation, helping protect sensitive control electronics from voltage spikes and noise on the load side. The potential-free output enables safe interfacing with external devices and higher voltages without common-ground constraints, reducing wiring conflicts and ground-loop risk.

With a single-channel, easy-to-wire solution, the ALL3003 simplifies integration into existing control systems while delivering reliable switching performance. It’s a practical choice for engineers and makers seeking safe, isolated switching in a compact form factor.
