Product Details
 | Fully configurable true RMS protection relay for protection of any size electric motor, transformers or distribution points. RS485 Modbus RTU, Profibus, USB, IRDA. |
 | M500 Motor protection relay for any size electric motor with configurable outputs, event logging, RS485 MODBUS RTU communication and infra red remote control. |
 | The units are suitable for a wide range of applications, like mining, agriculture, food, chemical and shipping industries and more. |
 | The M440 and M400 Motor manager was designed to control and protect pumps and related units such as motors. Through effective managements systems, the units save lives and electricity. The motor will only operate when necessary thus also on wear and tear. |
 | It is a fully configurable relay and offers true RMS voltage measurement up to 2500Vac phase to phase and true RMS current measurements up to 6500. |
 | The Ex IA Pilot relay offers intrinsic safe pilot wire protection. |
 | Battery monitor and controller for 128VDC battery operated vehicles. |
 | Accurate carbon monoxide monitor for fixed installations. The CO levels are displayed on the highly visible alpha numeric display. 4-20mA and RS485 Modbus RTU is standard. |
 | Robust intrinsic safe (Exia I) smoke detector for industrial applications. The S16 offer low power consumption, microprocessor controlled 3 sensor smoke analysis, up to 3three 4-20mA outputs or RS485 Modbus RTU communication. |
 | Voltage Converter 380V
Voltage Converter 525V
Voltage converter 1000V |
 | Intrinsic safe Exia I dual channel barrier. |
 | Infra red remote control handheld device for programming for most of our products. |
 | The EL1 Earth Leakage protection relay is the most advanced Earth Leakage protection on the market to date. The EL1 measures true RMS (harmonic immune) sensitive earth leakage accurately from 25mA to 10.0A. |
