Description

Converters E1854EL are designed to measure current and voltage in AC single-phase circuits. Converters can be used for control of currents and voltages of electrical systems, installations and automation of various objects of power engineering and industry. The converters provide the following features: software selection of current or voltage input signal, measuring range; software selection of analogue output signal range; formation of discrete output signal when the set threshold value is reached; display of input signal on the indicator as a percentage of the nominal value; data transmission via RS485 interface (Modbus RTU protocol). E1854EL are included in the State Register of measuring instruments of the Russian Federation No. 59809-15. Interverification interval - 8 years.
