function

KFD2-STC5-EX1.2O analog input safety barrierUsed for internal security applications. This device provides 2-wire and 3-wire smart transmitters for hazardous areas, and can also be used in conjunction with a 2-wire smart current source. It transmits the analog input signal in the form of 2 to the isolated current value in the safe area. The input signal can be overlaid with digital signals in dangerous or safe areas and transferred bidirectionally. If the HART communication resistance in the loop is too low, the internal resistance between terminals can be 250 Ω 8, 911 12 can be used. The test socket connected to the HART communicator is integrated into the terminal of the device.

application

The device supports the following smart protocols:

• HART
• BRAIN
• Foxboro
