ML-OP-524, Option board to supply (extra) power to sensors or peripherals

When designing a power efficient and cost effective product like our ML-x17 data logger your have to find a balance between features, costs and power consumption without compromising quality.

Regarding the sensor power switch we have chosen for a 12V power output as it is the most commonly used voltage to power external sensors.

If you want to connect sensors requiring 5V or 24V you could put a simple voltage regulator between the 12V output of the logger and the sensor, but its recommended to use our ML-OP-524 option board instead as it neatly integrates with our ML-x17 data logger, has a power efficient design and can be deployed in a versatile manner (i.e. to add additional sensor power in case the combined draw of your sensors exceeds 200mA@12V).

Specifications

• Output voltage selector
  • 5V@300mA
  • 12V@200mA
  • 24V@100mA
  
  
• Control mode selector
  • Constant
    Providing a constant output voltage (in case you have a low power sensor requiring power continuously).
    
    
  • Internal control
    The power is switched-on in parallel with the sensor power switch of the logger.
    
    
  • External control
    The power is switched on when applying a voltage between 3..24V on the control pin (e.g. the voltage output of the accessory port to power an Iridium EDGE satellite transceiver).
    
    
  • External inverted control
    The power is switched off when applying a voltage between 3..24V on the control pin. (e.g. to switch on the power from the open collector alarm output).
