The MTL4521 is a loop-powered solenoid valve/alarm driver, mainly used in hazardous areas. Below is its detailed introduction:
- Input: 4-20mA loop current
- Output: Output current up to 147mA, sufficient to drive most solenoid valves and alarms
It can be used in Zone 0, IIC Group, T4 hazardous areas, as well as Division 1, Group A hazardous locations.
Input voltage range: 20-35V DC
- Minimum output voltage: 13.6V at 48mA
- Maximum output voltage: 24V at 180Ω load
- Current limit: 48mA
- Output ripple: Less than 0.5% of the maximum output (peak-to-peak)
The output can reach within 10% of the final value in 100ms.
Equipped with a yellow LED indicator light for displaying the output status, which turns on when the output is activated.
90mA at 24V.
Internal power consumption is 1.4W at 24V.
It has intrinsic safety characteristics and can be used in hazardous areas with explosion risks.
