The 10K-M is a robust, durable leak detection controller with a small footprint and a unique enclosure that allows it to be mounted on a DIN rail.  The 10K-M does not have a web interface.

The 10K-M Features:

  • Distance-read leak detection.
  • Monitors up to 10,000 feet (3,048 meters) of RLE’s chemical sensing cable.
  • Compatible with SeaHawk chemical sensing cable.
  • Includes the leader cable and EOL that are compatible with chemical sensing cable.
  • Audible and visible alarm notification.
  • Panel and DIN rail mountable enclosure.
  • Can be networked with other RLE web-accessible controllers or any other Modbus RTU-equipped monitoring system.

Make Sure You Have An Isolated Power Supply!

RLE leak detection controllers, including the 10K-M, require an isolated power supply. A power supply is not included with the 10K-M. Purchase an RLE power supply – PSWA-DC-24-ST or WA-AC-24-ST.
