Overview

KFD2-STC5-1.2O multiplier isolator, with one input and two outputs, one input signal 4-20mA and two output signals 4-20mA.

Product Details

KFD2-STC5-1.2O Beckhoff isolatorPower the HART smart transmitter and transmit the measurement signal to the safe or hazardous area. The active current signal is transmitted to the safe area. Its characteristics are as follows:

1. Single channel;

2. 2-channel isolated output;

3. Electromagnetic compatibility meets NAMUR NE21;

4. According to IEC61508, the safety level can reach SIL2.

KFD2-STC5-1.2O Beckhoff isolatorIts main function is to distribute power for 2-wire intelligent transmitters, andKFD2-STC5-1.2O Beckhoff isolatorTransmitting analog signals. The HART communication overlaid on a 4-20mA current allows for bidirectional transmission.
