• 24 V DC supply (loop powered)
• Current limit 45 mA at 12 V DC
• Housing width 12.5 mm
• Up to SIL3 acc. to IEC 61508
KCD0-SD-EX1.1245开关量输出安全栅功能
This isolated barrier is used for intrinsic safety applications. It
supplies power to solenoids, LEDs, and audible alarms
located in a hazardous area.
It is loop powered, so the available energy at the output is
received from the input signal. The output signal has a
resistive characteristic. As a result the output voltage and
current are dependent on the load and the input voltage.
At full load, 12 V at 45 mA is available for the hazardous area
application.
