Features & Benefits At A Glance
RGB Tech Spec

Rugged - Use in the harshest of environments

Compatible with virtually any SCADA

Ultra Low Power

Secure platform to protect your assets and data

Rugged design

The Kingfisher LP-3 is packaged in a two-part, rugged plastic enclosure which measures just 185mm (H) x 130mm (W) x 50mm (D) and houses the electronics and communication interfaces, ensuring it can withstand even the harshest environments.

Compatible & Easy Configuration

The Kingfisher LP-3 is compatible with virtually any SCADA, providing customers and partners with the flexibility you require.

The LP-3 supports ISaGRAF and all IEC 61131-3 Languages, saving you time on site with easy configuration and a library of pre-engineered function blocks.

Ultra-Low Power consumption

Intelligent management of power consumption allows the Kingfisher LP-3 to be battery or solar powered.

When operating it draws as little as 24mW and in sleep-mode has a current draw of less than 1mA, minimising the size and cost of the required power supply.
