Solenoid Driver, KFD2-SLD-Ex1.13100
- 1-channel isolated barrier
- 24 V DC supply (Power Rail)
- Logic input
- Output 100 mA at 13 V DC
- Alternating outputs for the operation of solenoids with 2 coils
- High output power for IIB gas group
- Line fault transparency (LFT)
- Test pulse immunity
- Up to SIL 3 acc. to IEC 61508
This isolated barrier is used for intrinsic safety applications.
The device supplies power to solenoids, LEDs and audible alarms located in a hazardous area.
The device has 2 alternating outputs, in order to be able to operate a valve with 2 coils.
If both inputs are energized, then only output I is energized.
The device is immune to the test pulses of various control systems.
The line fault transparency function can display a line fault in the field by a change in impedance at the switching input of the solenoid driver.
A fault is signalized by LEDs acc. to NAMUR NE44 and a separate collective error message output.
