Product Information

PA-4111 is a switch quantity isolator. It receives the switch quantity signal at site and isolates and converts it to relay output. Signal isolation can effectively inhibit different interference and prevent field switching equipment from not operating. This kind of product is suitable for both the 35.5mm guide rail installation and baseboard installation, being compatible with MTL4504. Product features: 1. Power indicator lamp (green) 2. Input, output, and power supply complete isolation;

Technical Parameters:

1. Number of channels: one channel; 2. Power supply: 18-30VDC; 3. Consumption power: ＜1W; 4. Power supply voltage at site sensor side: about 8V (at open circuit); 5. Passive switch input (dry contact signal): Short-circuit current: 8mA; Open-circuit voltage: 8V. 6. Active switch input (current signal): When the site input current >2.1mA, it means "ON"; When the site input current ＜1.2mA, it means "OFF"; 7. Switch hysteresis: 200us; 8. Relay output characteristics: Response time: 20ms; Drive capacity: 250VAC/2A, 30VDC/2A 9. Load type: resistive load; 10. Insulation strength: 1500VAC/min; 11. Operating temperature: -10℃-+60℃; 12. Operating humidity: ＜90%RH (no condensate water); 13. Shell material: PC flame-resistant; 14. Weight: about 100g; 15. Boundary dimensions (thickness x width x height): 15x101x123mm.
