Brand: Measurement Technology Ltd. (MTL)
Model: MTL3046B
Type: Repeater Power Supply (Intrinsically Safe)
Part Number: MTL3046B
Technical Specs:
- Function: Provides a fully-floating DC supply for energizing ‘smart’ 2-wire 4/20 mA transmitters in a hazardous area, repeating the current in a separate circuit to drive a safe-area load, with support for superimposed digital communication signals (e.g., HART)
- Number of Channels: 1, fully floating
- Input Signal Range: 4 to 20 mA with superimposed digital signal
- Output Signal Range: 4 to 20 mA
- Voltage Available for Transmitter and Lines: ≥15 V at 20 mA
- Safe-Area Load Resistance: Not specified (typically 0 to 600 Ω for similar models; confirm with datasheet)
- Hazardous-Area Input:
- Maximum Voltage (Uo): 28 V
- Maximum Current (Io): 93 mA
- Maximum Power (Po): 0.65 W
- Permissible Inductance (Lo): 4.2 mH
- Permissible Capacitance (Co): 0.13 µF
- Permissible Inductance/Resistance Ratio (Lc/Rc): 55 µH/Ω
- Supply Voltage: 20 to 35 V DC, 125 mA max
- Power Dissipation: <1.5 W
- Isolation: 250 V AC between input, output, and power supply terminals
- Operating Temperature Range: -20°C to +60°C
- Storage Temperature Range: -40°C to +80°C
- Maximum Ambient Temperature: 60°C
- Enclosure Rating: IP20
- Mounting: 35 mm DIN rail
- Hazardous Area Certifications:
- ATEX: [EEx ia] IIC, Baseefa No. Ex 89C2112
- Other: Suitable for Zone 0, IIC, T4-T6 hazardous areas
- Additional Features:
- Compatible with majority of ‘smart’ transmitters
- Provides explosion protection for equipment and wiring in all zones and explosive atmospheres
- Alternative to shunt-diode safety barriers where isolation is essential or a high-integrity earth is unavailable
