The MTL5032 is a pulse isolation barrier that provides isolation protection for switches, proximity switches, current pulses, and voltage pulses in hazardous areas, suitable for Zone 0 and Class IIC hazardous areas. Below are its specific details:
1 channel
- Proximity Switch Input: Excitation voltage 7.0 to 9.0V DC, 1kΩ nominal; switch hysteresis 0.2mA (650Ω) nominal, compliant with NAMUR and BS EN 60947-5-6:2001 standards.
- Current Pulse Input: Supplies power to the transmitter at 16.5V DC (at 20mA); line current 24mA; output ON when I > 9.0mA, OFF when I < 7.0mA, with switch hysteresis of 0.5mA.
- Voltage Pulse Input: Input impedance > 10kΩ; switching point voltage (V₋) 3.6V or 12V nominal.
- Safe-Area Pulse Output: Maximum delay 10μs; maximum off-state voltage 35V; maximum off-state leakage current 10μA; maximum on-state resistance 25Ω; maximum on-state current 50mA.
- Safe-Area Current Output: Input capture delay of 2 signal cycles (minimum 5ms); signal range 4 to 20mA; maximum/minimum range 0 to 22mA; load resistance 0 to 450Ω @ 20mA; output resistance > 1MΩ; ripple < 50μA (peak-to-peak); accuracy better than 20μA (at 20℃); temperature drift < 1μA/℃; rise time (10%-90% after step change) 60ms.
- Alarm Output: Relay energizes when alarming; output rating: maximum 0.5A @ 35V DC.
- Pulse Width: Minimum 10μs (high level), minimum 10μs (low level).
- Frequency Range: 0-50kHz (pulse output mode); 0-10kHz (for analog output).
- Green: Power indicator.
- Yellow: Lights up when the output circuit is on.
- Red: Lights up when a line fault or error occurs.
- 65mA at 24V; 70mA at 20V; 55mA at 35V.
- Maximum 1.35W at 24V; maximum 1.75W at 35V.
Terminal-related parameters comply with specific standards (e.g., Terminals 2-1 and 6-1: Uo=10.5V, Io=14mA, Po=37mW). Non-energy-storing devices can be connected to any intrinsically safe circuit without further certification under specific conditions (≤1.5V, ≤0.1A, ≤25mW; open-circuit voltage < 28V).
Mainly used in industrial control fields. Leveraging intrinsic safety technology, it allows the use of conventional instruments and cables, reducing costs, and is suitable for intrinsic safety protection of low-voltage instruments.
