The MTL5041 is a 4/20mA current isolator for 2-wire transmitters, primarily used for intrinsic safety isolation of signals in hazardous locations. Here is its detailed description:
Signal range: The input signal range in hazardous areas is 0-24mA (including over-voltage range), with the transmitter voltage being 16.5V at 20mA; the output signal range in safe areas is 4-20mA.
Load impedance: The load impedance in safe areas is 0-1kΩ, and the output impedance is greater than 2MΩ.
Power supply requirements: The operating power supply is 20-35VDC.
Response time: It can stabilize to within 10% of the final value within 250μs.
Current consumption: At a 20mA signal, the current consumption is 70mA at 24VDC, 85mA at 20VDC, and 55mA at 35VDC.
Insulation performance: The insulation voltage between the input, output, and power supply terminals is 250Vrms.
Transfer accuracy: At 20℃, the transfer accuracy is 20μA (with a typical value of 5μA).
Operating temperature: The operating temperature range is -20℃ to +60℃, and the storage temperature range is -40℃ to +80℃.
Installation method: It uses 35mm top-hat rail mounting, complying with EN 50022-35x7.5, BS 5584, and 35x27x7.3 DIN 46277 standards.
Weight: Approximately 110g.
Explosion-proof certifications: It holds various explosion-proof certifications such as FM (USA) and CSA (Canada), and can be used in Class I, II, and III hazardous locations.
