8-Channel 24V DC Sourcing Transistor Output – Fast Response:Uses solid-state transistor outputs with switching time < 100 μs, ideal for high-speed applications like pulse output, fast logic control, and counter feedback.
High Reliability – No Mechanical Wear, Long Service Life:Contactless design eliminates mechanical wear and arcing, offering significantly longer lifespan than relay outputs, perfect for frequent switching.
Standard 24V DC Output – Industry-Compliant:Provides 24V DC output signal, compatible with standard industrial devices such as PLC inputs, optocouplers, small relays, and indicator lamps.
Galvanic Isolation for Strong Noise Immunity:Features 500V AC isolation between field outputs and backplane bus, protecting the CPU from electrical disturbances and ensuring stable operation.
LED Indicators for Real-Time Output Status:Each channel has a green LED that lights up when the output is active, enabling visual diagnostics and on-site troubleshooting.
