Product Description

Product Description

Pepperl Fuchs KCD2 - STC - Ex1 

In industrial settings, especially those involving hazardous areas, ensuring the safety of electrical equipment is of utmost importance. The Pepperl Fuchs KCD2 - STC - Ex1 Transmitter Power Supplies Safety Barrier emerges as a crucial component in maintaining this safety while enabling seamless communication and power supply for various industrial devices. This safety barrier is designed to meet the stringent requirements of industries such as oil and gas, petrochemicals, mining, and any other sector where the presence of flammable gases, vapors, or dust poses a risk of explosion.

Measurement and Signal Processing

1.Input for 2 - Wire Smart Transmitters and Current Sources:
One of the key features of the KCD2 - STC - Ex1 is its ability to interface with 2 - wire smart transmitters and current sources. In hazardous areas, these transmitters are used to measure various process variables such as temperature, pressure, flow, and level. The safety barrier provides a stable power supply to these 2 - wire devices, ensuring their proper operation. 
2. Output Options:
The safety barrier offers versatile output options. The output can be configured as either a current source, sink mode, or a voltage output via DIP switches. This configurability allows the KCD2 - STC - Ex1 to be integrated seamlessly into different control systems. For example, in a control system that requires a current - based input for further processing, the safety barrier can be set to output a current signal in the range of 4 mA to 20 mA. 
3. Signal Isolation and Transmission:
The isolation feature of the KCD2 - STC - Ex1 plays a crucial role in signal transmission. It ensures that the analog input signal from the hazardous area is transferred to the non - hazardous area as an isolated current value. 

Communication Capabilities

1.Support for Smart Protocols:
The KCD2 - STC - Ex1 is designed to support a variety of smart protocols. This enables it to communicate effectively with different types of smart transmitters and other devices in the industrial network. For example, it can work with transmitters that use the HART protocol. HART is a widely used protocol in industrial automation, allowing for two - way digital communication over a 4 - 20 mA analog current loop. With the KCD2 - STC - Ex1, technicians can remotely access and configure the connected smart transmitters, retrieve diagnostic information, and perform calibration tasks. This not only simplifies the maintenance process but also improves the overall efficiency of the industrial process control system.
2.HART Communication :
When used in a HART - compatible setup, the KCD2 - STC - Ex1 offers additional features. If the HART communication resistance in the loop is too low, the internal resistance of 250 Ω between terminals 6 and 8 can be used. This internal resistance can be utilized to optimize the HART communication signal, ensuring reliable data transfer. Additionally, test sockets for the connection of HART communicators are integrated into the terminals of the device. 

Safety Features and Compliance

1.Intrinsic Safety for Hazardous Areas:
The primary function of the KCD2 - STC - Ex1 is to provide intrinsic safety in hazardous areas. Intrinsic safety is a concept that ensures that any electrical equipment used in a hazardous area cannot generate enough electrical energy or heat to ignite the surrounding flammable substances. The KCD2 - STC - Ex1 achieves this by limiting the electrical energy that can reach the hazardous area. It is designed to operate within the safety limits defined by relevant standards such as IEC/EN 60079 - 11. This standard specifies the requirements for electrical apparatus for use in explosive gas atmospheres, and the KCD2 - STC - Ex1 complies with these requirements, making it a reliable choice for use in hazardous areas.
2. Safety Integrity Level :
The KCD2 - STC - Ex1 is rated up to SIL 2 according to IEC 61508. SIL is a measure of the safety integrity of a safety - related system. A SIL 2 rating indicates that the safety barrier has a relatively high level of safety integrity. It means that the probability of a dangerous failure of the safety barrier is low. In industrial processes where safety is critical, such as in oil refineries or chemical plants, the use of a safety barrier with a high SIL rating like the KCD2 - STC - Ex1 is essential to ensure the overall safety of the operation.
