Merlin Data Logger SDL1200

Merlin Data Logger SDL1200

Quick Overview

The Merlin data logger is a compact, low power multi channel device capable of handling a range of analogue and serial inputs and logging data at speeds of up to 50Hz. It has 10 analogue inputs with a 0-5V input range. Seven of these inputs can also be configured to read frequency inputs from flow meters. The unit also has a serial RS485 port for connection to Keller digital pressure sensors, and other serial devices. The logger also has a high contrast backlit LCD display for viewing real time readings, with the option of a second display where large format text is required.

  • Integral sensors for x,y,z acceleration and temperature
  • 10 analogue 0-5v, 1 thermocouple and 1 serial input.
  • Up to 7 analogue inputs can be configured for frequency inputs from flow meters
  • Maximum logging rate 1Hz for all channels or 20Hz on up to 3 Keller pressure sensors
  • Multiple logging rate possible within one project
  • User programmable
  • Supports voltage (0-5v) and  frequency inputs
  • 1 serial channel for RS485 MODBUS data or other protocols as required
  • Serial channel can read up to 8 Keller pressure sensors.
  • Optional high contrast LCD display with backlight
  • Backlight can be turned on and off via a light sensor.
  • Internal memory 10M reading
  • SD memory card slot
  • External power supply11-30vDC
  • Power consumption 7mA with display backlight on , 4mA with display off


The logger is supplied with windows software and logging projects are easily configured via the menu driven interface. In addition to taking instantaneous readings the logger can also record, minimum, maximum and average values. Each channel can be set with two logging rates: a slow rate for normal data capture and a fast rate which can be triggered by an analogue threshold for fast logging.

The logger has a large high contrast backlit LCD display, with the option to have a second display fitted. The display is programmable via the software and can be set to show either 12 channels, 3 channels. The dual display option is particularly useful in applications where a number of channels are required to be displayed in large text such as in subsea applications where real time values need to be viewed by an ROV camera.

 The logger display can show up to 12 channels


 A second external display can be fitted as an option
