Voltage- and Frequency-Relay UFR1001E Grid- and Plant Protection according to VDE-AR-N 4105:2018-11, vde-ar-n 4110 and grid codes G59/3 + G83/2 with integrated Vector-Step-Relay The UFR1001E from ZIEHL industrie-elektronik monitors voltage and frequency in plants for own generation of electricity. It fulfills the requirements of VDE-AR-N 4105 and bdew for Germany, ÖVE/ÖNORM for Austria, G59/3 and G83/2 for UK and DIB V VDE 0126-1-1 for many countries in Europe with supplements VFR2013/2014 for France. The UFR1001E is a dual-channel device and thus one-fault-proof. Input-circuit, A/D-converter, processor and output-relay are doubly present. The processors control each other. The function of the output-relays and of the connected switches can be monitored with feed-back contacts. At an alarm the devices switches off and the reason is displayed with LEDs and signaled with transistor-outputs. The limits are pre-set according to VDE-AR-N 4105. They can be changed if required and be protected with a code and/or a seal. An alarm-counter stores the last 100 alarms with reason and elapsed time. In addition the time the UFR1001E has interrupted the plant is recorded. All values can be read-out with the integrated display and give the operator valuable information about the availability of the plant. With a test-button the function of the connected switches can be tested and their switching-time can be measured. The simulation displays the complete switching-time of device plus connected switches. When feeding into medium voltage, limit, hysteresis, alarm-delay and switch-back-delay can be individually set for U>>, U>, U, F

Temperature Relay Type TR640IP
Sensors 4 x Pt 100, Pt 1000 or PTC thermisors, 4 limits, analog outputs or interface RS485, IP interface, operation with browser via TCP/IP.

Temperature Relays TR640IP monitor up to 4 sensors for up to 4 limits. Different sensors can be connected at the same time, e.g. Pt 100 (RTD) and PTC thermistors. Typical applications are monitoring of motors, generators or transformers. An other application is the use as a two or more step controller with additional monitoring of over- or undertemperature or monitoring of differences in temperatures of 2 sensors.

Preset programs allow easy setting e.g. monitoring of transformers with/without monitoring of temperature of core or with/without controlling a ventilator.
Operation can be made at the device or with a standard browser via Ethernet.
