Intrinsic Safety Barriers KFD2-STC5-Ex1.2O SMART Transmitter Power Supply 24V

Overview

KFD2-STC5-Ex1.2O is a power isolation safety barrier that provides intrinsically safe power for 2-wire/3-wire SMART transmitters and 2-wire SMART current sources in hazardous areas. It isolates and converts the 4-20mA analog input signal in the hazardous area into two independent 4-20mA output signals for transmission to the safe area.

Specification

FAQ:

1.Does KFD2-STC5-Ex1.2O support HART communication?

KFD2-STC5-Ex1.2O supports HART communication and provides complete HART transparent transmission function:

1. Protocol compatibility: supports HART, BRAIN and Foxboro SMART protocols simultaneously
2. Integrated test point: A dedicated test socket for HART communicator is integrated on the terminal, allowing HART devices to be connected for debugging and diagnosis without breaking the loop.
3. Signal transmission: HART digital signal can be superimposed on the 4-20mA analog signal for bidirectional transmission between hazardous areas and safe areas
4. Resistor configuration: If the HART communication resistance in the control loop is too low, you can use the 250Ω resistor provided by the device to ensure normal communication.
5. Application scenarios: Designed for connecting 2-wire and 3-wire HART-compatible smart transmitters in hazardous areas to safe area control systems

2.What is the SIL safety level of KFD2-STC5-Ex1.2O?

The KFD2-STC5-Ex1.2O has a SIL safety level of SIL 2 (SC 3) in accordance with IEC/EN 61508.

3.Which hazardous areas is KFD2-STC5-Ex1.2O suitable for?

KFD2-STC5-Ex1.2O is Ex ia intrinsically safe:

1. Gas environment: Zone 0, Zone 1, Zone 2, Class IIC
2. Dust environment: Zone 20, Zone 21, Zone 22, Class IIIC
3. Mine Environment: Supports Class I M1 Methane Hazardous Environment
4. Protection level: Ga / Da / Ma (highest level)
