Product Description

Product Description

MTL4541 

The MTL4541 is primarily designed as a repeater power supply for 4 - 20 mA current loops. Its main function is to provide a fully - floating DC supply for energizing conventional 2 - or 3 - wire 4/20 mA transmitters located in hazardous areas. Once the transmitter in the hazardous area is powered, the MTL4541 repeats the current in another floating circuit to drive a safe - area load. This process effectively separates the electrical circuits of the hazardous and safe areas, preventing electrical sparks or excessive energy transfer that could potentially cause an explosion in the hazardous area.

For HART (Highway Addressable Remote Transducer) 2 - wire transmitters, the MTL4541 offers an additional advantage. It allows bi - directional communications signals to be superimposed on the 4/20 mA loop current. This means that not only can the analog 4 - 20 mA signal be transmitted and processed, but also digital information related to the transmitter's status, calibration, and other parameters can be communicated in both directions. This is extremely useful in modern industrial setups where intelligent transmitters are widely used, as it enables remote configuration, monitoring, and troubleshooting of the transmitters.

1. Technical Specifications

1.1 Signal Ranges
Hazardous Area Input: The signal range for the input in the hazardous area is 0 to 24 mA, which includes over - range conditions. This wide range allows the module to handle various types of input signals from different sensors or transmitters, even in cases where there might be temporary signal fluctuations or abnormal readings.
Safe Area Output: In the safe area, the output signal range is 4 to 20 mA, which is the standard industrial analog signal range for representing process variables. Additionally, for under - range or over - range conditions, the output can extend to 0 to 24 mA. This ensures that the receiving equipment in the safe area can accurately interpret the status of the process variable being measured in the hazardous area, even if it is outside the normal operating range.
1.2 Voltage - Related Parameters
Transmitter Voltage: When the current is 20 mA, the voltage provided to the transmitter is 16.5 V. This voltage is sufficient to power most 2 - or 3 - wire 4/20 mA transmitters in hazardous areas while maintaining the safety requirements.
Maximum Voltage Source: The maximum voltage source that the MTL4541 can handle is 24 V DC. This limits the input power supply to a level that is safe for use in industrial applications, especially in environments where electrical safety is critical.
1.3 Load Resistance and Current Sink
Safe - Area Load Resistance (MTLx541): When the current is 24 mA, the load resistance in the safe area can range from 0 to 360 Ω. At 20 mA, this range extends to 0 to 450 Ω. These load resistance values are important as they determine the compatibility of the MTL4541 with different types of loads in the safe area, such as controllers, recorders, or other monitoring devices.
Safe - Area Load (MTLx541S): The MTLx541S variant acts as a current sink for safe - area connections. It can handle a maximum current sink of 600 Ω. This functionality is useful in certain applications where the load requires a different type of electrical connection or where the electrical characteristics of the load demand a current - sinking capability.

 2. Safety Features and Certifications

2.1 Intrinsic Safety
The MTL4541 is intrinsically safe, which means that it is designed to prevent the ignition of flammable gases, vapors, or dusts in hazardous areas. It limits the electrical energy that can be released into the hazardous area to a level that is insufficient to cause an explosion. This is achieved through a combination of circuit design, component selection, and electrical isolation techniques.
2.2 Safety Descriptions
Terminal Isolation: Between terminals 2 to 1 and 3, the parameters are specified as Uo = 28 V, Io = 93 mA, Po = 651 mW, and Um = 253 V rms or DC. These values represent the maximum allowable voltage, current, and power that can be present at the terminals while still maintaining the safety of the system. For example, the maximum open - circuit voltage (Uo) of 28 V ensures that in the event of a circuit malfunction, the voltage available to potentially ignite a flammable substance in the hazardous area is below the ignition threshold.
Connection to IS Loops: The MTL4541 can be connected to any Intrinsic Safety (IS) loop with an open - circuit voltage of less than 28 V without further certification. This makes it highly versatile and easy to integrate into existing industrial safety - critical systems. It also simplifies the installation process, as there is no need for additional complex safety certifications or modifications when connecting to compliant IS loops.
2.3 SIL Certification
The MTL4541 has been evaluated and can be used in IEC 61508 functional safety applications. Safety Integrity Level (SIL) certification is a measure of the reliability and safety of a system or component in performing a safety - related function. The fact that the MTL4541 has SIL certification indicates that it meets strict international standards for safety - critical applications. In industries such as oil and gas, where a malfunction in the control system could have catastrophic consequences, the SIL - certified MTL4541 provides an added layer of confidence in the overall safety of the system.
