1. Universal Signal Compatibility – Supports both NPN (LowLevel) and PNP (Level) input signals, making it compatible with microcontrollers, I/O boards, PLCs, and other control systems. Each channel features an independent LED indicator for clear trigger signal visibility. 2. Performance Isolation – Optocoupler isolation ensures reliable signal conversion and protects sensitive equipment from voltage spikes and electrical noise. Suitable for control signals ranging from 1.8 V to 24 V. 3. Flexible Output Current – Converts input signals into NPN output with a wide voltage range (3.3 V 24 V) and a robust 200 mA sink current per channel, ideal for driving relays, solenoid coils, and other industrial loads. 4. DURABLE EASY INSTALLATION – Features a flameretardant plastic housing and 35 mm DIN rail mounting design for secure and spacesaving installation in control cabinets. Compact dimensions (80 × 49 × 30 mm) suit various industrial applications.
