Mains frequency&voltage monitoring relay
download pdf file The combined voltage and frequency relays are designed for applications where a voltage and/or a frequency needs to be monitored. UFWA are combined over- and under voltage and frequency relays.
PT100 TEMPERATURE TRANSMITTER
download pdf file The measuring transducers type TAMA and TAMB are used for measuring the temperature with a PT100 sensor according to DIN IEC 751.
3 PHASE UNDER VOLTAGE CONTROL RELAY with PHASE SEQUENCE DETECTION
download pdf file The 3 phase 4 wire voltage relays are designed for applications where the three phases need to be individually monitored for under voltage against neutral and correct phase sequence. The PNDA and PNDI offers a true time delay on drop out even at total power failure. The relay works in "fail safe"mode and need no external power supply.
3 Phase under voltage control relay with phase sequence detection
download pdf file The 3 phase 4 wire voltage relays are designed for applications where the three phases need to be individually monitored for under voltage against neutral and correct phase sequence.

LOAD MONITOR Power Factor cos ϕ
download pdf file The load monitor determines the angle cosφ.which is the phase shift between current and voltage of asynchronous motors. The load monitor is directly connected to the motor and no additional sensors are required. Because the phase angle depends on motor loading, it represents a directly measurable variable for the motor loading. The set point cosφ reacts either to an excessive or insufficient freely selectable phase angle. After a set period of time, the relay R switches to failure position and the LED is switched on.
MULTIFUNCTION CURRENT RELAY
download pdf file The current relay is designed with a micro-controller.With programmable range, function and timing it can be programmed to cover all kinds of applications. The monitored current is fed through an internal shunt with a voltage is then amplified in a balanced amplifier, rectified, averaged and compared with a preset reference voltage.AC and DC current between 1 mA and 10A can be measured directly.By means of a current transformer or a shunt resistor the range can be extended without limits.
5mA to 100A MULTIFUNCTION AC CURRENT RELAY WITH INTERNAL CT
download pdf file The current relay is designed to cover all possible AC current monitoring and control applications-including differential current measuring (earth leakage)-in the range from 5mA to 100A. Higher sensitivity can be achieved by pulling the current carrying wire multiple times through the relay. The wide range, 4 decades, are divided into 12 sub ranges for easy adjusting.For an external monitoring of the actual input, there is a 20mA output signal related to the max. of the set range.
4 to 20 mA DC CURRENT RELAY with SENSOR SHORT PROTECTION
download pdf file The current relay is designed to be used as a trip relay in a 4 to 20mA current loop. The ILUA comes with single turn potentiometers for the set point an the different, and the ILUB with multi-turn potentiometers for precise setting. The differential is adjustable from 1 to 20% of the set tripping current. The relay is powered from an external 16 to 32 VDC source, and includes a 35mA current limits, a Red LED will be it and in case of with a common 0 to 2 sec. adjustable timer for pull in and drop out. The timer can as an option be specified up to 30 sec. and disabled for either pull in or drop Out delay.
