MTL4544S is an analog input isolation barrier. The detailed information is as follows:
Dual channels
- Supports 4-20mA signals, suitable for 2-wire or 3-wire smart transmitters.
- Minimum output voltage at 20mA: 16.5V
The safe side of MTL4544S can provide passive signal output, powered by the DCS card (24V).
Supports HART communication (only for terminals 1 & 2 and 4 & 5)
Better than 15μA
Isolation voltage between the safe area and hazardous area: 250V AC
1.9W
1.58cm × 10.98cm × 12.36cm (length × width × height, standard industrial component dimension format)
- Net weight: Approximately 0.11kg
- Shipping weight: 1.5kg
Stabilizes to within 10% of the final value in 50μs
- For terminals 2 to 1 & 3, and 5 to 4 & 6: The relevant parameters are Uo = 28V, Io = 93mA, Po = 651mW, Um = 253V rms or DC.
- For terminals 1 to 3 and 4 to 6: These are simple devices (1.5V, 0.1A, 25mW), which can be connected to any intrinsic safety circuit with an open-circuit voltage of less than 28V, no further certification required.
- Complies with standards GB 3836.1-2010, GB 3836.4-2010, and GB 3836.20-2010.
- Explosion-proof mark: (Ex ia Ga) IIC
- Maximum operating temperature range: -20℃ to +60℃
- HART Communication: Abbreviation for "Highway Addressable Remote Transducer Protocol", an international standard for bidirectional communication between industrial field devices and control systems, retained as-is to conform to industry technical terminology.
- Ex ia Ga IIC: A standard explosion-proof mark in accordance with GB 3836 standards: "Ex" indicates explosion-proof, "ia" represents intrinsic safety type (suitable for Zone 0 hazardous areas), "Ga" is the equipment protection level (highest level for explosive gas environments), and "IIC" is the gas group (covers highly explosive gases such as hydrogen and acetylene).
- 2-wire/3-wire Smart Transmitter: Common types of industrial analog transmitters (e.g., pressure, temperature transmitters); "2-wire" transmitters share power and signal lines, while "3-wire" transmitters have separate power and signal lines, and the terms are retained to reflect device compatibility.
