Function Description
The KCD0-SD-Ex1.1245 is a loop-powered isolated barrier used for intrinsic safety applications, specifically designed to supply power to solenoids, LEDs, and audible alarms located in hazardous areas.
How it works:
- Loop-powered operation – Derives operating power directly from input signal
- Resistive output characteristic – Voltage and current dependent on load and input voltage
- Output performance – Delivers 12 V at 45 mA to power field devices
- Intrinsic safety – Certified for [Ex ia Ga] IIC for Zone 0, 1, and 2 hazardous areas
- Reinforced isolation – 300 Veff between input and output circuits
Typical Applications
- Solenoid Valves – Pilot-operated valves for pneumatic systems
- Annunciators – Visual indicator panels for process alarms
- Audible Alarms – Horns and sirens for plant-wide alerts
- LED Indicators – Status lights on hazardous area equipment
